Age Calculator

Our age calculator works by taking your date of birth and an "as of" date, then computing the exact difference between them. It calculates the precise number of years, months, days, hours, minutes, and seconds you have been alive. The calculator accounts for leap years, different month lengths, and time zones to ensure 100% accuracy.
