Age Calculator
Work out an exact age in years, months and days, and how long until the next birthday.
This tool runs in your browser. Nothing you enter is sent anywhere.
Enter a date of birth and, if you like, a different "age at" date, such as the day of an application or an event. The age is counted in whole years and months, then days.
A birthday on 29 February is treated as 28 February in years that are not leap years.
