How this is worked out
Your age goes up by one on each birthday, so knowing only your birth year leaves two possible answers: the current year minus 1991, or one less if your birthday hasn't come yet. Pick your birth month and day above to get your exact age in years, months and days, or use the full age calculator.
The Chinese zodiac follows the lunar new year, which falls between January 21 and February 20, so people born early in 1991 may belong to the previous animal. Generation names follow the ranges commonly used by Pew Research Center.
