What are the exact dates for each zodiac sign?

Imagine you are at a birthday dinner and someone across the table asks, 'So what's your sign?' You hesitate. Maybe your birthday sits right on the edge between two signs, or maybe you once read your horoscope and thought, that is not me at all. You just want a clear answer.

The short answer: Your zodiac sign is the sign the Sun was in on the day you were born. Find your birthday in the dates below. If you were born within a day or two of a change, a free natal chart calculator will settle it for good.

The twelve signs split the year into roughly equal parts, each with its own traits, element and planetary ruler.

Aries (about March 21 to April 19) starts at the spring equinox, the astrological new year. Cardinal fire, ruled by Mars: courage, initiative, competitive energy.

Taurus (April 20 to May 20). Fixed earth, ruled by Venus: stability, sensuality, determination.

Gemini (May 21 to June 20). Mutable air, ruled by Mercury: communication, curiosity, adaptability.

Cancer (June 21 to July 22) begins at the summer solstice. Cardinal water, ruled by the Moon: emotional depth, nurturing, protective instincts.

Leo (July 23 to August 22). Fixed fire, ruled by the Sun: creativity, confidence, natural leadership.

Virgo (August 23 to September 22). Mutable earth, ruled by Mercury: analytical thinking, service, attention to detail.

Libra (September 23 to October 22) begins at the autumn equinox. Cardinal air, ruled by Venus: harmony, justice, partnership.

Scorpio (October 23 to November 21). Fixed water, ruled by Pluto and Mars: intensity, transformation, emotional depth.

Sagittarius (November 22 to December 21). Mutable fire, ruled by Jupiter: adventure, philosophy, optimism.

Capricorn (December 22 to January 19) begins at the winter solstice. Cardinal earth, ruled by Saturn: ambition, discipline, strategic planning.

Aquarius (January 20 to February 18). Fixed air, ruled by Uranus: innovation, humanitarianism, independence.

Pisces (February 19 to March 20). Mutable water, ruled by Neptune: intuition, creativity, spiritual sensitivity.

These dates are approximate, because the exact moment the Sun enters each sign moves by one to two days each year. Earth's orbit takes about 365.25 days while the calendar has 365, and leap years correct the extra quarter-day.

If you were born near a boundary, an ephemeris for your birth year, or a natal chart calculator that uses the exact solar ingress time, gives you a definite answer.

Once you know your sign, the next words to learn are its element and modality. Fire, Earth, Air & Water: The Four Elements in Astrology covers the first, and Cardinal, Fixed & Mutable Signs: The Three Modalities Explained covers the second.

Why does the zodiac year start with Aries instead of January?

The astrological year starts with Aries because it lines up with the spring equinox (around March 21), when the Sun crosses the celestial equator heading north. That moment marks the start of the tropical zodiac, the system Western astrology uses.

Ancient astrologers chose it because it stands for new beginnings in nature: seeds sprouting, days lengthening, life coming back after winter. January as the start of the year is a Roman convention with no link to astronomical or astrological cycles.

Which zodiac sign covers my birthday in each month of the year?

Every month holds two signs, with the switch in the third week:

January: Capricorn through the 19th, Aquarius from the 20th. February: Aquarius through the 18th, Pisces from the 19th. March: Pisces through the 20th, Aries from the 21st. April: Aries through the 19th, Taurus from the 20th. May: Taurus through the 20th, Gemini from the 21st. June: Gemini through the 20th, Cancer from the 21st. July: Cancer through the 22nd, Leo from the 23rd. August: Leo through the 22nd, Virgo from the 23rd. September: Virgo through the 22nd, Libra from the 23rd. October: Libra through the 22nd, Scorpio from the 23rd. November: Scorpio through the 21st, Sagittarius from the 22nd. December: Sagittarius through the 21st, Capricorn from the 22nd.

Do the zodiac constellations still match the zodiac signs?

No. Because of precession (the slow wobble of Earth's axis over a 26,000-year cycle), the constellations have shifted about 23 degrees from the signs since the system was set down. So the Sun now sits in the constellation Pisces during what Western astrology calls Aries season.

Western tropical astrology deliberately follows the seasons, not the constellations, so this shift does not change how it works. Vedic astrology uses the sidereal system, which does account for precession.

What is the significance of being born at the very beginning or end of a sign?

Born at the start of a sign (zero to five degrees), the Sun had just arrived, and the energy is said to be at its purest and most initiating.

Born at the end (25 to 29 degrees, called the anaretic degree zone), the Sun is finishing its pass through the sign. Astrologers read that energy as carrying gathered wisdom, plus an urgency to master the sign's lessons. Neither is better or worse. Each simply has a different flavor from births in the middle degrees.

What does your sun sign actually reveal about your personality?

If you have ever read your sign and felt seen, or felt nothing at all, this is what is going on underneath. Your sun sign stands for your core identity: your ego, your conscious sense of self, your creative expression and your life purpose. When astrologers say 'you are an Aries' or 'you are a Pisces', they mean the archetype your conscious self is built around.

Think of it as the operating system of your personality. Your other planets and placements are the apps, but the sun sign is the platform they all run on.

In astrology the Sun stands for vitality, willpower and the drive to become your most authentic self. Your sun sign describes the qualities you are growing into over your lifetime, the challenges you are meant to face and the gifts you are meant to offer. It is your life's central theme, not a full description of you in every moment.

Fire sun signs (Aries, Leo, Sagittarius) are developing courage, creative self-expression and the ability to inspire through passionate action. Their theme: learning to lead, create and spread warmth.

Earth sun signs (Taurus, Virgo, Capricorn) are developing practical mastery, care of material things and the ability to build what lasts. Their theme: learning to build, refine and sustain.

Air sun signs (Gemini, Libra, Aquarius) are developing clear thinking, social intelligence and the ability to connect people through ideas. Their theme: learning to communicate, harmonize and innovate.

Water sun signs (Cancer, Scorpio, Pisces) are developing emotional wisdom, intuitive depth and the ability to transform through feeling. Their theme: learning to nurture, transform and transcend.

The sun sign gets the most attention because it is the easiest to find. All you need is a birth date. But professional astrologers stress that it accounts for only about one-third of your astrological personality.

The Moon sign (emotional needs and instinctive reactions) and the Rising sign (the face you show the world, and the lens every planet works through) matter just as much. If your sun sign horoscope never seems to fit, your Moon or Rising horoscope may fit far better.

Once you know which sign holds your Sun, the individual sign guides go deeper into strengths, shadow patterns and relationship style, starting with Aries Personality Traits: The Complete Guide to the Ram.

Why do some people not relate to their sun sign?

A few things can make your sun sign feel foreign. A heavily filled Moon or Rising sign can dominate your personality, so those descriptions feel more like you. Planets closely conjunct the Sun can change how it shows up. The Sun's house placement decides which part of life it shines through most. And hard aspects to the Sun from outer planets can mute or redirect its energy.

If your sun sign does not feel like you, look at your Moon sign, Rising sign and the sign holding the most planets in your chart.

What is the difference between a sun sign, a star sign, and a birth sign?

Sun sign, star sign, birth sign, zodiac sign and horoscope sign all mean the same thing: the sign the Sun was in on the day you were born. Star sign is the common British term. Sun sign is what astrologers prefer, because it names the body being measured. Birth sign is casual usage.

None of them means your Moon sign or Rising sign. If an app asks for your sign without asking for a birth time, it wants your sun sign.

How does the sun sign interact with the moon sign?

Your sun sign is your conscious identity and how you express yourself on purpose. Your moon sign is your emotional nature and your instinctive reactions.

When the two get along (same or complementary elements), what you want and what you feel tend to agree. When they clash (square or opposite elements), you may feel a tug-of-war between your rational goals and your emotional needs. Both setups create valuable, just different, personality dynamics. Which one sounds more like the inside of your head?

What is a rising sign and why does it matter?

Your rising sign (Ascendant) is the sign rising on the eastern horizon at the exact moment you were born. It changes about every two hours, which is why you need a birth time to calculate it.

It works like a filter for how all your planetary energy reaches the world. It governs first impressions, physical appearance tendencies and how you approach new situations. Many people are first seen as their rising sign rather than their sun sign, which is why strangers sometimes guess your sign wrong.

How do you find your zodiac sign if you do not know your birth time?

If you have no idea what time you were born, you are not stuck. For almost every birthday you can find your sign without it, because the Sun stays in one sign for around 30 days. Only the day or two around a sign change is truly unclear.

Enter your birth date, year and city into a free natal chart calculator and set the time to 12:00 noon, the standard convention for an unknown time. The Sun moves roughly one degree a day, so a twelve-hour error shifts it by about half a degree. That only matters if your birthday falls within about 24 hours of the moment the Sun changed signs that year.

If the noon chart puts your Sun at 29 degrees of one sign or zero degrees of the next, your birth time decides it. For every other birthday, a noon chart settles your sun sign for good. It also gives reliable positions for Mercury, Venus, Mars and the outer planets, none of which move fast enough for a half-day error to matter, except right on a sign boundary.

What a noon chart cannot give you is your Rising sign, your house placements, and sometimes your Moon sign.

The Moon is the one placement a noon chart handles badly. It covers twelve to fifteen degrees a day, roughly half a sign, so a birth time off by twelve hours can shift it six or seven degrees.

A noon-chart Moon in the middle degrees of a sign is right whatever your birth time. But one within about seven degrees of a boundary could belong to the next sign, and those two options describe very different emotional needs.

Where can I find my exact birth time?

The long-form birth certificate is the most reliable source. It is different from the short abstract certificate most people carry, which often leaves the time out. Ask the vital records office where you were born for the long-form copy.

Other places to check: hospital birth records, a baby book or birth announcement a parent kept, and the memory of whoever was in the room. Even a remembered time like 'just after the evening news' narrows the window.

Which parts of my birth chart are unreliable without a birth time?

Three parts: the Rising sign, the twelve house cusps, and sometimes the Moon sign. The Ascendant moves through all twelve signs in a single 24-hour period, so without a time it is unknown, not just approximate.

Every house cusp is anchored to the Ascendant, so the whole house framework goes too, and nobody can say which area of life a planet sits in. The Sun, Mercury, Venus, Mars and outer planets stay accurate, so aspects between planets are still readable.

What is a cusp birthday and does being born on the cusp give you traits of two signs?

If you were born near a sign change and have always felt like two signs at once, you are not imagining it, though the reason may surprise you. A cusp birthday means you were born within about two to three days of the Sun moving from one sign to the next. That moment varies by year, so people born on cusp dates may be either the ending or the beginning sign.

Being 'on the cusp' is one of the most debated topics in popular astrology. In strict astrological terms, you are one sign or the other. The Sun cannot be in two signs at once.

But the feeling of being influenced by both has some astrological basis beyond the Sun. Near a sign boundary, your Mercury and Venus, which always travel close to the Sun, are likely to be in the neighboring sign. Someone born on April 19 might be an Aries Sun with Mercury in Taurus and Venus in Pisces, or a Taurus Sun with Mercury and Venus in Aries. Those inner planets create blends that feel like cusp energy, even though the Sun itself is firmly in one sign.

Each of the twelve cusps has its own character. The Aries-Taurus cusp (April 16-22) blends pioneering energy with practical determination. The Taurus-Gemini cusp (May 17-23) mixes sensual stability with curiosity. Many people find their cusp blend matches their experience, even though the real mechanism is planet placement, not a Sun caught between signs.

Cusps show how popular astrology and technical practice can drift apart. Pop astrology describes cusps as blended solar energy. Professional astrologers explain the cusp feeling through how close your personal planets (Mercury, Venus, Mars) sit to sign boundaries.

A full natal chart reading clears up most cusp confusion. It shows exactly which planets are in which signs, and why you might feel a neighboring sign without your Sun actually being there.

How can I determine my exact sign if I was born on a cusp?

You need three things: your birth date, your birth year and, ideally, your birth time. Free natal chart calculators like those at astro.com or cafeastrology.com work out the Sun's exact position at your birth and place it firmly in one sign.

If you do not know your birth time, the calculator can still settle most cusp dates with just the date and year, since the Sun usually changes signs during a specific hour that year.

What are the date ranges for all twelve zodiac cusps?

Popular astrology names twelve cusps, each covering roughly a week around a sign change:

Pisces-Aries: March 17-23 Aries-Taurus: April 16-22 Taurus-Gemini: May 17-23 Gemini-Cancer: June 17-23 Cancer-Leo: July 19-25 Leo-Virgo: August 19-25 Virgo-Libra: September 19-25 Libra-Scorpio: October 19-25 Scorpio-Sagittarius: November 18-24 Sagittarius-Capricorn: December 18-24 Capricorn-Aquarius: January 16-22 Aquarius-Pisces: February 15-21

These windows are wider than the one or two days of real solar uncertainty, because they cover the range where Mercury and Venus often sit in the neighboring sign.

Do cusp babies really have traits of both signs?

Many people born near a boundary say they feel both signs, and there is an astrological explanation that does not need the Sun to be in two places.

At the very end of a sign, the Sun's energy is said to carry the gathered wisdom and fatigue of that sign. At the very beginning, it carries fresh, raw, initiating energy. On top of that, Mercury and Venus often sit in the neighboring sign, adding real influence from both. The experience is real. The mechanism is just more nuanced than simple solar blending.

Which cusps are considered the most powerful?

The four cusps that fall on seasonal turning points carry special weight: Pisces-Aries (spring equinox), Gemini-Cancer (summer solstice), Virgo-Libra (autumn equinox) and Sagittarius-Capricorn (winter solstice).

Astrologers see these as cosmic pivot points where the basic direction of solar energy shifts. People born on them often report a strong sense of transition and transformation, and an ability to bridge different ways of being, which reflects the significance astrologers give their birth timing.

Why is your Vedic astrology sign different from your Western zodiac sign?

If you have ever had an Indian astrologer tell you that you are a different sign, and felt a little thrown, here is why. Your Vedic sign is usually one sign earlier than your Western sign, because the two systems measure from different starting points.

Western astrology uses the tropical zodiac, which pins zero degrees Aries to the March equinox, keeping the signs locked to the seasons. Vedic astrology, called Jyotish, uses the sidereal zodiac, which pins the signs to the background stars. As Earth's axis precesses, it drifts against the calendar.

The gap between them is the ayanamsa, currently around 24 degrees. Subtracting it moves most people's Sun back one sign, so only births in roughly the last six days of a Western sign keep the same sign in both.

The sidereal sun signs, called rashis, change around the middle of each month rather than the third week. Sidereal Aries runs from about April 14 to May 14, sidereal Taurus from about May 15 to June 14. A Taurus born on May 2 is a Vedic Aries. A Taurus born on May 18 stays a Taurus in both.

Vedic astrology also treats the Moon sign, not the Sun sign, as the main marker of identity. That is why an Indian astrologer asking for your sign usually wants your janma rashi, the sign the Moon held when you were born.

Neither system corrects the other. Each is consistent inside its own frame, like two maps of the same city drawn from different starting points.

Which is my real zodiac sign, the Western one or the Vedic one?

Both are real within their own systems. Your Western tropical sign describes your link to the seasonal cycle, so a Libra born at the autumn equinox is correctly a Libra there. Your Vedic sidereal sign describes your position against the fixed stars, so the same person is correctly a Virgo in Jyotish.

Read your tropical sign in Western sources and your sidereal sign in Vedic sources, rather than deciding one overrides the other.

What is a nakshatra and how is it different from a zodiac sign?

A nakshatra is one of 27 lunar mansions in Vedic astrology. Each spans 13 degrees 20 minutes of the sidereal zodiac, compared with a zodiac sign's 30 degrees.

Those finer slices give a more specific reading than the rashi alone. Ashwini at the start of Aries is read as swift and healing, Rohini in Taurus as fertile and magnetic, and Ashlesha at the end of Cancer as penetrating and serpentine. Your nakshatra comes from the Moon's position, so working it out needs a birth time and place.

How does your zodiac sign connect to the bigger picture of your birth chart?

Your sun sign is the first chapter of your story, not the whole book. It is one piece of a larger map called the natal chart or birth chart, which records where every celestial body was at the moment you were born. Seeing how your sun sign fits into it turns astrology from a personality quiz into a real tool for understanding yourself.

The chart includes ten primary bodies (Sun, Moon, Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto), each in one of the twelve signs and one of twelve houses. Nobody born at a different time and place shares your exact combination.

Sun: your core identity. Moon: your emotional nature, what you need to feel safe and how you react under stress. Mercury: how you think and communicate. Venus: how you love and what you find beautiful. Mars: how you assert yourself and what drives your ambition. Jupiter: where you find luck and growth. Saturn: your challenges, and where discipline builds mastery. Rising sign (Ascendant): the lens all these energies pass through on the way to the outside world.

When someone says 'I am a Leo' but acts more like a Virgo, they likely have strong Virgo placements in their Moon, Rising or inner planets. When someone fits their sun sign perfectly, their other placements usually back it up rather than pull against it. The full chart tells the whole story; the sun sign is chapter one.

Modern astrology leans more and more on the full chart, which is why a professional reading feels so different from a newspaper horoscope. A skilled astrologer reading your whole chart can spot patterns, tensions and potential that sun sign analysis alone cannot show.

If you have found sun sign astrology interesting but a bit vague, a full natal chart reading is the natural next step, and it usually gives far more accurate and nuanced insight.

Which is more important: sun sign, moon sign, or rising sign?

All three matter, but they do different jobs. The sun sign is who you are becoming and your conscious life purpose. The moon sign is who you are emotionally and what you need to feel secure. The rising sign is how you come across and how you instinctively meet new situations.

In practice, the rising sign tends to lead first impressions, the moon sign leads your private life and close relationships, and the sun sign grows stronger as you mature into your authentic self.

How do I get my complete birth chart?

Free natal charts are available at astro.com, cafeastrology.com and many astrology apps. You need your birth date, birth time and birth place.

Birth time is critical, because it sets your rising sign, your house placements and the Moon's exact position. If you do not know it, check your birth certificate or contact the hospital where you were born. An approximate time is better than none, though an exact one gives the most accurate chart.

Can your zodiac sign change over your lifetime?

Your natal chart, sun sign included, is fixed at birth and never changes. What changes is how you experience it, as you mature, meet transiting planets and hit milestones like your Saturn return (around age 29 and 58).

Many people feel more like their sun sign as they get older, because growth helps them live it more fully. Progressed charts, which move your natal chart forward symbolically through time, can also shift your progressed Sun into a new sign every 30 years, adding new layers to your personality.

What are the most common myths about zodiac signs?

If you have ever been told your sign means you are doomed to be jealous or bad at love, let that go. Plenty of myths get in the way of using astrology well.

Myth: your sign decides your fate. This is the most damaging one. Astrology describes tendencies, potential and archetypal patterns, not fixed destinies. A Scorpio is not doomed to be jealous, and a Gemini is not destined to be unfaithful. Growth, environment, choices and self-awareness all shape how your tendencies play out.

Myth: some signs should never date. Sun sign compatibility is a rough guide, not a rule. The happiest couple you know might be a 'terrible' match on paper, while textbook pairs can be miserable. Full chart comparison (synastry) shows compatibility details that sun signs completely miss.

Myth: astrology is proven, or totally baseless. Both are oversimplifications. Controlled studies have not confirmed a causal mechanism by which planetary positions affect personality. Yet astrology's long cross-cultural history, and the resonance millions of people feel with their chart descriptions, suggest it captures something meaningful about human psychological patterns, whether through cosmic mechanism, archetypal psychology or a mix of factors we do not yet understand.

Myth: there are only twelve types of people. This may be the most common misconception. With ten planets, twelve signs, twelve houses and dozens of aspects between planets, the number of possible charts is essentially infinite. No two people share an identical natal chart unless born at the same moment in the same place.

Media treatment of astrology as entertainment, rather than a complex symbolic system, has fed many of these myths. Newspaper horoscopes have to apply one forecast to one-twelfth of the global population, so they are bound to be vague and often wrong.

That is a failure of the format, not of astrology. Judging astrology by newspaper horoscopes is like judging medicine by fortune cookies. Real natal chart interpretation looks very little like the simplified sun sign astrology most people meet in the media.

Ranking articles such as Most Loyal Zodiac Signs Ranked: Who You Can Really Trust describe one trait across twelve archetypes. They are not verdicts on any individual, including you.

Is there any scientific evidence for astrology?

The evidence is limited and contested. Michel Gauquelin's studies in the mid-twentieth century found statistically significant correlations between planetary positions at birth and professional eminence in specific fields, though his methods and findings are still debated.

No widely accepted study has shown a causal mechanism by which distant celestial bodies shape individual personality. Some argue that the lack of a proven mechanism does not necessarily disprove the phenomenon, and may only mean current scientific models cannot yet explain what astrology observes.

Does my zodiac sign change if I was born in the Southern Hemisphere?

No. Someone born in Sydney on August 1 is a Leo, exactly like someone born in London on August 1. The tropical zodiac is defined by the Sun's position along the ecliptic, which is the same from everywhere on Earth.

What changes is the seasonal imagery. Aries opens spring in the north but autumn in the south, and Capricorn starts the northern winter while the south is at midsummer. A minority of southern astrologers argue for reversing the signs to keep that seasonal logic, but standard practice keeps the northern convention.

Why do zodiac descriptions seem to fit almost everyone?

The Barnum effect (or Forer effect) is our tendency to accept vague personality descriptions as uniquely accurate. General zodiac descriptions lean on it.

Detailed natal chart readings that include every planet, house and aspect are much more specific. They either land strongly or miss completely, which practitioners take as a sign they are reaching beyond generic statements. The gap in accuracy between sun sign descriptions and full chart readings is dramatic.

Should I make important life decisions based on my zodiac sign?

Astrology works best as a tool for self-reflection and spotting patterns, not as an oracle for decisions. Use your chart to understand your tendencies, strengths and growth areas, then decide based on a practical look at your real situation.

The mature approach is neither blind faith nor dismissal. It is thoughtful engagement: one lens among many for understanding yourself and the people you love.

Questions people ask

How do I find my zodiac sign?

Your zodiac sign is set by where the Sun was on your birth date. The Sun moves through each of the twelve zodiac constellations over the year, spending roughly 30 days in each sign. Just find your birthday here: Aries (March 21-April 19), Taurus (April 20-May 20), Gemini (May 21-June 20), Cancer (June 21-July 22), Leo (July 23-August 22), Virgo (August 23-September 22), Libra (September 23-October 22), Scorpio (October 23-November 21), Sagittarius (November 22-December 21), Capricorn (December 22-January 19), Aquarius (January 20-February 18), Pisces (February 19-March 20).

What if I was born on a cusp between two signs?

If you were born within two to three days of a sign change (the cusp), the Sun may have been in either sign, depending on the exact moment it moved that year. You are technically one sign or the other, not a blend. To know for sure, you need your birth year and ideally your birth time, then check an ephemeris or a free natal chart calculator online. Many cusp-born people feel both signs because other planets in their chart may sit in the neighboring sign.

Is my zodiac sign the same as my horoscope sign?

Yes. Your zodiac sign, also called your sun sign or star sign, is what daily horoscopes are based on. But your full astrological profile holds much more: your Moon sign (emotions), Rising sign or Ascendant (how others see you), Mercury sign (communication style), Venus sign (love style) and Mars sign (drive and anger), plus the positions of Jupiter through Pluto. Your sun sign is the foundation, but it accounts for only about one-third of your astrological personality.

Why do zodiac sign dates shift slightly each year?

Sign dates can move by a day or two between years because the astronomical year does not line up perfectly with the calendar. The Sun enters each sign at a slightly different moment each year, because of the 365.25-day orbital period against the 365-day calendar. That is why most date ranges are approximate. If you were born near a sign change, checking the exact solar ingress time for your birth year gives you a definite answer.

Do zodiac signs actually affect personality?

The scientific community has not validated a causal mechanism by which planetary positions affect personality. Still, astrology has been practiced for thousands of years in almost every culture, and millions of people find zodiac descriptions meaningfully match their experience. Whether it works through cosmic influence, psychological archetypes or self-fulfilling prophecy, its value as a tool for self-reflection and understanding others is well established by its lasting global popularity.

What is the difference between Western and Chinese zodiac signs?

Western zodiac signs depend on your birth month and are based on the Sun's position against twelve constellations. Chinese zodiac signs depend on your birth year and cycle through twelve animals (Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Goat, Monkey, Rooster, Dog, Pig) on a twelve-year rotation. The two systems are unrelated, but you can use them together for a richer personality picture. Vedic (Indian) astrology uses a third system, based on sidereal rather than tropical zodiac calculations.

Is there a 13th zodiac sign called Ophiuchus?

Ophiuchus is a constellation the Sun passes through astronomically, but it is not part of the Western tropical zodiac most astrologers use. The tropical zodiac divides the ecliptic into twelve equal 30-degree segments based on the seasons, not the constellations, so the number and size of the background constellations do not matter. Claims about a 13th sign go viral every so often, but they mix up astronomical constellations with astrological signs.
