Questions and answers
How is age calculated?
Age is the number of full years since the date of birth, then the full months since the last birthday, then the remaining days.
When is the birthday of someone born on 29 February?
In years without a 29 February, the calculator uses 28 February, which is the most common convention.
Is the date of birth sent anywhere?
No. The calculation happens in your browser and nothing you type is stored or sent.
