Age Calculator
Calculate your exact age, total days lived, and time until your next birthday.
How this age calculator works
Choose a date of birth to calculate completed years, months, and days. Total days use calendar dates, so daylight-saving changes do not alter the answer.
Example
Choose January 1, 2000 to see completed years, months, days, total days, and the next birthday countdown.
Privacy
