The 12 signs and their dates

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 it works: the Western zodiac divides the year into 12 signs in a fixed order, each tied to a span of calendar dates. Your sign is simply the span your birth month and day fall into — the year does not matter. The four elements repeat in a cycle: Fire (Aries, Leo, Sagittarius), Earth (Taurus, Virgo, Capricorn), Air (Gemini, Libra, Aquarius), and Water (Cancer, Scorpio, Pisces).

Cusp dates: if you were born on the first or last day of a sign's range, different popular tables occasionally shift the boundary by a day, because the underlying astronomy (the moment the sun enters a sign) varies slightly by year and time of day. This calculator uses the standard date ranges shown above, which are the ones most commonly published.

Frequently asked questions

Does my birth year change my sign? No. In the Western system the sign depends only on month and day. (The Chinese zodiac, by contrast, works by year — there is a separate calculator for it on this site.)

What if I was born on a cusp? Use the ranges on this page as the standard answer. A birth chart drawn for your exact birth time and place can place the sun's sign change on a specific hour, which is why cusp birthdays are the one case where sources sometimes disagree by a day.

What are the elements? A traditional grouping of the signs into Fire, Earth, Air, and Water, three signs each, shown in the result above.
