How it works

Exact calendar age, Korean age conventions, total days lived and next birthday countdown.

Full age: completed years since birth. Year age: reference year minus birth year. Counting age: year age plus one. Animal zodiac uses the Gregorian birth year, not lunar New Year or the start of spring.
