What is My Zodiac Sign?
How the Sign Is Found
Your sign is the part of the year the Sun was in on your birthday. Western astrology uses the tropical zodiac — twelve equal 30° arcs of the Sun’s yearly path, counted from the March equinox. The calculator picks the row of the fixed table below that holds the day and month; the year does not change the row. The actual moment the Sun changes sign depends on the year and the time and is not calculated here.
| Sign | Starts | Ends |
|---|---|---|
| ♈ 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 |
Limits
- Boundary days: on the first and last day of a sign the answer can depend on the year and the time of birth — the Sun changes sign at a particular hour.
- Only the Sun sign: the Moon sign and the ascendant need the time and place of birth.
- Vedic (sidereal) astrology counts from the stars and usually gives the previous sign — see the FAQ.

FAQ
How is a zodiac sign worked out from a date?
Western astrology uses the tropical zodiac: the yearly path of the Sun is cut into twelve equal arcs of 30°, measured from the March equinox, and your sign is the arc the Sun stood in on that date. Nothing but the date is needed, which is why this calculator asks for nothing else.
What if I was born on the first or the last day of a sign?
The Sun crosses a sign boundary at a particular hour, and that hour drifts by up to about a day between years, because the year is 365.2422 days long and leap days keep pulling it back. This page uses the conventional fixed date ranges, so a birth on a boundary day is worth checking against an ephemeris for that exact year and time of birth.
Why does a Vedic or Indian horoscope give me a different sign?
Vedic astrology uses the sidereal zodiac, anchored to the stars, while the Western one is anchored to the March equinox. Precession has pulled the two about 24° apart — roughly 24 days — so a sidereal chart usually places a person in the sign before the one shown here.
Is Ophiuchus a thirteenth sign?
Astronomically the Sun really does pass in front of the constellation Ophiuchus, from about 30 November to 17 December. But the tropical zodiac is not a map of constellations: it is twelve equal 30° divisions of the solar year, so it has twelve signs by construction. The constellations themselves are wildly unequal — the Sun spends about seven days in Scorpius against about 45 in Virgo.
