About the Zodiac Sign Calculator
Your sun sign is the western zodiac sign that matches the date you were born. This zodiac sign calculator takes a date of birth and shows the sign and its symbol, the dates the sign covers, its element (fire, earth, air or water), its modality (cardinal, fixed or mutable), and the classical ruling planet. It also tells you the traditional birthstone for your birth month, the weekday you were born on and how many days remain until your next birthday. Zodiac signs have no scientific basis, so treat the results as entertainment and a fun conversation starter.

Frequently asked questions
How do I find my zodiac sign?
Match your birth date to the sign ranges. Aries runs from 21 March to 19 April, Taurus from 20 April to 20 May, and so on around the year, ending with Pisces from 19 February to 20 March. The calculator does the matching for you.
Why do some sources give different dates?
The sun enters each sign at slightly different moments from year to year, so signs begin on the 19th, 20th, 21st or 22nd depending on the year and your time and place of birth. Dates in this tool are the commonly published ones. If you were born close to a boundary, check an ephemeris for your exact birth time.
What are elements and modalities?
The twelve signs are split into four elements: fire (Aries, Leo, Sagittarius), earth (Taurus, Virgo, Capricorn), air (Gemini, Libra, Aquarius) and water (Cancer, Scorpio, Pisces). They are also grouped into three modalities: cardinal, fixed and mutable, which relate to the start, middle and end of each season.
Is astrology scientific?
No. Studies have found no reliable link between the position of the sun and planets at birth and personality or life events. People enjoy astrology as a tradition, a game and a way to talk about themselves, and that is the spirit of this tool.
What is a birthstone?
A traditional gemstone assigned to each month of the year, such as garnet for January, amethyst for February and opal or tourmaline for October. Lists vary by country and jeweller, and some months have more than one stone. This tool shows a commonly used one.
Does this include the Chinese zodiac?
No. The Chinese zodiac depends on the lunar new year, which changes date each year, so it needs a different calculation. This tool covers the western sun sign only.
