Frequently asked questions
Everything you need to know about the Age Calculator.
How is the exact age calculated?
It counts complete years since your birth date, then complete months since your last birthday, then the remaining days — the same way ages are calculated on official forms.
What if I was born on February 29?
In non-leap years your birthday is counted on February 28, so you turn a year older on Feb 28 and the countdown points there.
Can I calculate age on a past or future date?
Yes. Change the “age at” date to find out how old someone was, or will be, on any day — useful for exam, job or visa age limits.
