Zodiac Sign Calculator (Western + Chinese)

About this calculator

This calculator takes a birth date and returns two different traditions at once: the Western (tropical) zodiac sign, read from the calendar date ranges the twelve signs occupy — the tropical zodiac divides the year into twelve equal segments, which no longer line up with the constellations they are named after, and the Chinese zodiac animal, based on a 12-year lunar calendar cycle that assigns each year an animal like Dragon, Tiger or Rabbit.

It is used casually by anyone curious about horoscopes, compatibility readings or personality traits associated with their sign, and around Lunar New Year by people checking which animal a given year carries. Note that the animal here is taken from the Gregorian year, while the Chinese year actually turns in late January or February — so for a birth date before that turn, the traditional animal is the previous year's.
