How it is calculated
- We count full years first, then the remaining months, then the remaining days
- If the day count runs short, we borrow days from the previous month (for example 31 or 28)
- Total days, weeks and hours come from counting the days between the two dates
- For people born on 29 Feb, the birthday is counted as 1 March in non-leap years
Tips
- For government forms, enter the form's cut-off date in "Calculate age on"
- Date of birth cannot be in the future or after the "age on" date
Privacy
Your date of birth is used only in your browser. Nothing is saved or sent anywhere.
