Birth Chart Calculator
Enter your birth date, time and place to find your Sun sign, Moon sign and Rising sign, with a short reading for each.
What are the "big three"?
Astrologers often start with three placements. Your Sun sign is your core identity and the one you know from horoscopes. Your Moon sign describes your emotional nature, what you need to feel secure. Your Rising sign (or Ascendant) is the sign that was rising on the eastern horizon at the moment you were born, and it shapes how others first see you.
The Sun and Moon signs only need your date of birth, although the Moon changes sign every couple of days, so a birth time helps. The Rising sign changes about every two hours, so it needs your exact birth time and place. Your birth certificate or hospital records are the best source.
The 12 Sun signs
Aries
Bold, direct and energetic. Aries Suns lead from the front, act first and think later, and are at their best when there is something new to start or a challenge to win.

Cancer
Caring, protective and intuitive. Cancer Suns feel everything deeply, put family and home first, and lead by nurturing the people they trust.

Frequently asked questions
What is a birth chart?
A birth chart, or natal chart, is a map of where the Sun, Moon and planets were in the zodiac at the moment and place you were born. This calculator shows the three most talked-about placements: your Sun sign, Moon sign and Rising sign.
Why do I need my birth time?
The Sun stays in a sign for about a month and the Moon for about two and a half days, but the Rising sign changes roughly every two hours. Without a birth time you can still find your Sun sign and usually your Moon sign, but not your Rising sign.
Why is my Sun sign different from what I expected?
If you were born within a day or so of a sign change, the exact moment of birth and your time zone decide which sign the Sun was in. The dates printed in magazines are approximate and shift by a day from year to year.
Does this use tropical or sidereal astrology?
It uses the tropical zodiac, which is the system used by most Western astrology and by the horoscopes on this site. Vedic (Indian) astrology uses the sidereal zodiac, which gives different signs.
How accurate is the calculator?
Sun, Moon and Rising positions are calculated from standard astronomical formulas and are accurate to a fraction of a degree. The result is only as accurate as the birth time and place you enter, and near the edge of a sign you should double-check with a professional chart. Astrology is for reflection and entertainment, not advice.
What does your Rising sign mean?
