What is it?
The Zodiac Sign Calculator determines your Western (tropical) sun sign based on your birth month and day. The 12 signs each span roughly 30 days of the year: 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).
How to use
Select your birth month and enter your birth day. The calculator returns a numeric code (1–12) mapping to your zodiac sign. Use the label to read off your sign name.
Example scenario
Born June 15: Month = June (6), Day = 15. Since 15 < 21, the sign code is 3 = Gemini. Born July 25: Month = July (7), Day = 25. Since 25 is 23 or above, the sign code is 5 = Leo.
Pro tip
The four zodiac elements group signs by personality archetype: Fire (Aries, Leo, Sagittarius) — bold and energetic; Earth (Taurus, Virgo, Capricorn) — practical and grounded; Air (Gemini, Libra, Aquarius) — intellectual and communicative; Water (Cancer, Scorpio, Pisces) — emotional and intuitive. This calculator is for entertainment purposes only — there is no scientific evidence linking birth date to personality or destiny.
