Questions
How is age worked out for someone born on 29 February?
They turn a year older on 28 February in years without a 29 February, as most countries count it, and on 29 February in leap years.
Can I work out an age on a past or future date?
Yes. Change Age on to that date, such as the closing date of a form that asks for your age on a given day.
Is Age calculator free?
Yes, and as often as you like. It works in your browser, so there is nothing to sign up for.
Is what I type sent anywhere?
No. Everything is worked out in your browser, with its own time zone data, so nothing you type leaves your device.
Do I need to install anything?
No. It works in the browser on any computer, tablet or phone.
Can I use Age calculator from my own code?
You won't need to: every programming language can convert timestamps, time zones and dates with what it has built in. This page is for quick checks by hand.
