How the Age Is Calculated

Can I use this for someone else?
Yes, just enter their birthday and you'll get their age as of today. This is great for looking up public figures, historical figures, or friends.
How accurate is it?
Very accurate! It calculates age down to the day using JavaScript’s Date engine.
What if I was born on Feb 29?
The calculator will adjust correctly. In non-leap years, Feb 29 is treated as March 1 for age progression.
