Questions people ask
How is age calculated?
Count the whole years since the date of birth, then the whole months since the last birthday, then the days left over. Someone born on 15 May 1990 is 36 years, 4 months and 11 days old on 26 September 2026.
What about birthdays on 29 February?
In years without a 29 February, this calculator counts the birthday on 28 February, which is also how many legal systems count coming of age.
