Zodiac Sign Calculator

Your Western zodiac (sun) sign depends on your birthday: 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 and Pisces Feb 19–Mar 20.

A cusp birthday falls within a day or so of the change between two signs. The Sun's move into the next sign happens at a slightly different time each year, so people born on these dates should check a birth chart with their birth time and place to know their exact sign.

The Chinese zodiac follows the lunar calendar, and the year changes at Lunar New Year (between January 21 and February 20), not January 1. If you were born in January or early February, you may belong to the previous year's animal — this calculator checks the exact date for you.

Fire (Aries, Leo, Sagittarius), Earth (Taurus, Virgo, Capricorn), Air (Gemini, Libra, Aquarius) and Water (Cancer, Scorpio, Pisces). Signs of the same element, and Fire with Air or Earth with Water, are traditionally seen as most compatible.

Modern birthstones by month are: January garnet, February amethyst, March aquamarine, April diamond, May emerald, June pearl or moonstone, July ruby, August peridot, September sapphire, October opal, November topaz or citrine and December turquoise or tanzanite.

No scientific study has shown that zodiac signs predict personality or compatibility. Many people still enjoy astrology as a fun way to reflect on themselves and start conversations.
