How age is calculated
The calculator counts complete years first, then complete months, then the remaining days between your date of birth and the chosen date — the same way age is stated on official documents.
You can change the “Age on” date to find out how old someone will be on a future date (for exam or job eligibility cut-offs, for example) or was on a past date.
FAQ
What if I was born on 29 February? In non-leap years your birthday is counted as 28 February for the next-birthday countdown.
