Complete guide: Zodiac Sign
Updated:
This calculator assigns one of twelve Western tropical zodiac signs using fixed ranges. Aries begins on March 21; Capricorn spans December 22–January 19 across the year boundary. Both endpoints of each range are included.
It does not calculate the Sun's astronomical position. Actual transitions vary with year, time and time zone; near a boundary this conventional result may differ from an ephemeris. It does not determine ascendant, Moon sign or a natal chart.
The displayed element comes from astrological tradition: fire, earth, air or water. It is not a person's physical property. Sidereal zodiac and astronomical constellations are different systems and are not calculated here.
Entertainment and symbolic reflection: there is no scientific evidence that these numbers or signs predict personality, the future or relationship success.

Frequently asked questions
What if I was born at a sign boundary?
