Free Venus sign and Mars sign calculator
Venus and Mars sign calculator
Your Venus sign shows how you love and what attracts you. Your Mars sign shows how you desire, chase and get turned on.
Pop in your birthday and this free calculator finds both from where the planets really were the day you were born. A birth time is optional.
How the Venus and Mars calculator works
Your birthday. We place Venus and Mars where they really were on that day, using the astronomy-engine library on the tropical zodiac Western astrology uses.
A check for sign changes. We look across your whole birth day. If either planet changed sign that day, we say so and show the moment it moved.
Your birth time, if you have it. Add it to settle a sign change day. It is read in the time zone of your device.
Venus spends three to five weeks in a sign and Mars about six or seven, so most birthdays give one clear answer.
Venus and Mars signs: questions people ask
- What is my Venus sign?
- Your Venus sign is the zodiac sign Venus was in on the day you were born. It describes how you love, what you find attractive and how you like to be treated in a relationship. Venus spends about three to five weeks in each sign, so it is often different from your sun sign.
- What is my Mars sign?
- Your Mars sign is the zodiac sign Mars was in when you were born. It describes how you go after what you want: your drive, how you flirt and chase, your sexual energy and how you handle conflict. Mars usually stays in a sign for about six to seven weeks, and longer when it turns retrograde.
- Do I need my birth time to find my Venus and Mars signs?
- Usually not. Venus and Mars move slowly, so your birthday alone gives the right sign on most days of the year. The exception is a day when one of them changed sign. On those days this calculator tells you it may be in either sign, shows the moment it moved, and asks for your birth time.
- What is the difference between Venus and Mars in astrology?
- Venus is how you love and Mars is how you desire. Venus shows what attracts you, how you show affection and what makes you feel loved. Mars shows how you pursue, what turns you on and how you act when you want something. Together they make your love signature.
- How accurate is this Venus sign calculator?
- It works out where Venus and Mars really were, using the astronomy-engine library, which is accurate to about a minute of arc. Positions are tropical, measured on the ecliptic of the date, which is what Western astrology uses. Astrology itself is a tool for reflection, not a scientific prediction.
- Can I use my Venus and Mars signs to check compatibility?
- Yes. Astrologers compare one person's Mars with the other's Venus to read attraction and sexual chemistry. Our free sexual chemistry calculator does that from two birthdays and reads all four Venus and Mars contacts between you.
