How to find your zodiac sign
Your Western zodiac sign (also called your sun sign) depends only on the month and day you were born. Match the date to the ranges below.
| Sign | Dates |
|---|---|
| Aries | March 21 to April 19 |
| Taurus | April 20 to May 20 |
| Gemini | May 21 to June 20 |
| Cancer | June 21 to July 22 |
| Leo | July 23 to August 22 |
| Virgo | August 23 to September 22 |
| Libra | September 23 to October 22 |
| Scorpio | October 23 to November 21 |
| Sagittarius | November 22 to December 21 |
| Capricorn | December 22 to January 19 |
| Aquarius | January 20 to February 18 |
| Pisces | February 19 to March 20 |
Worked example. A birthday on April 20 is Taurus (April 20 to May 20), and it is the first day of that range, so it is flagged as a cusp. A birthday on December 25 is Capricorn (December 22 to January 19).
About the dates. Published ranges differ by a day between sources: Wikipedia's table, which it labels approximate, starts several signs a day later than Astrology.com. This tool uses the Astrology.com ranges. Astrology is a cultural tradition and entertainment, not a science.
Frequently asked questions
What is my zodiac sign by birthday?
Find your birth month and day in the table. Capricorn runs from December 22 to January 19 and Pisces from February 19 to March 20, for example.
Does my birth year change my zodiac sign?
No. The Western sun sign depends only on month and day. Your Chinese zodiac animal depends on the year, so use the Chinese zodiac calculator for that.
What if I was born on the edge between two signs?
Sources disagree by a day on some boundaries, and this tool uses one published set of dates. The first and last day of each range is flagged so you know to check the source you trust.
Is this a scientific tool?
No. It looks up a date range. Treat the result as fun, not as a prediction.
