Exact age, not just the year
The age calculator compares a date of birth with today (or any date you pick) and shows the age in completed years, months and days. It also shows the total number of months, weeks, days and hours lived, the day of the week of birth, and how many days remain until the next birthday.
Sports clubs often need an athlete’s age on a specific date – for example on the cut-off day of an age category. Simply change the "Age on this date" field.
How the age is calculated
A year is counted once the birthday has been reached; a month is counted once the same day of the month has been reached. People born on February 29 have their birthday on February 28 in common years in this calculator.
Frequently asked questions
Is my date of birth stored?
Only in your own browser, so it is filled in next time. It is never sent to our server.
How do I find someone’s age on a past or future date?
Change the "Age on this date" field to the date you need.
