Find The Correct Chinese Lunar Year.
The first step is identifying which Chinese lunisolar year contains your birth date. Chinese New Year usually falls between January 21 and February 20 on the Gregorian calendar, although its exact date changes annually.
For example, Chinese New Year began on February 17 in 2026. Someone born on February 16, 2026, therefore belongs to the preceding lunar year, associated with the Wood Snake. Someone born on February 17 belongs to the new Fire Horse year.
This distinction is why a complete birth date gives a more useful answer than a simple Gregorian birth-year lookup. The calculator uses calendar data rather than assuming January 1 marks the zodiac transition.
