Frequently Asked Questions
How do I find my zodiac sign by birthday?
Match your birth month and day to the sign date ranges: Aries Mar 21 – Apr 19, Taurus Apr 20 – May 20, Gemini May 21 – Jun 20, Cancer Jun 21 – Jul 22, Leo Jul 23 – Aug 22, Virgo Aug 23 – Sep 22, Libra Sep 23 – Oct 22, Scorpio Oct 23 – Nov 21, Sagittarius Nov 22 – Dec 21, Capricorn Dec 22 – Jan 19, Aquarius Jan 20 – Feb 18, Pisces Feb 19 – Mar 20. Or just type your birthdate into the checker above.
What are cusp dates, and does my birthday fall on one?
A cusp is a birthday within a day or so of a sign boundary, like Mar 20–21 (Pisces/Aries) or Dec 21–22 (Sagittarius/Capricorn). The Sun’s position shifts slightly every year, so the boundary date moves by roughly a day depending on your birth year. If the checker flags a cusp, an exact ephemeris for your birth year gives the definitive sign.
Why do some sources list slightly different zodiac dates?
There are a few reasons: the Sun crosses each boundary at a slightly different time every year, some astrologers use sidereal (constellation-based) zodiac dates shifted about 24 days later, and older tables round differently. The ranges used here are the conventional tropical dates used by most Western horoscope columns.
What do element and modality mean in astrology?
Each sign pairs an element (Fire, Earth, Air, Water) with a modality (Cardinal, Fixed, Mutable). Element describes temperament — Fire is energetic, Earth practical, Air mental, Water emotional. Modality describes style — Cardinal signs initiate, Fixed signs sustain, Mutable signs adapt. Every element contains one sign of each modality.
Is my zodiac sign the same as my star sign?
Yes — “zodiac sign,” “star sign,” and “Sun sign” all refer to the sign the Sun occupied at your birth in the tropical zodiac. It is only one piece of a full natal chart, which also tracks the Moon and planets, but it is the sign most horoscopes are based on.
