How the age calculator works
Your age is counted in full years, then the remaining full months, then the remaining days, the same way you would count on a calendar. Change the second date to see how old you were, or will be, on any day: a wedding, a graduation or a retirement date.
Fun ways to use it
- Find the day you turn 10,000 days old and celebrate it.
- Check exactly how old someone was on a historic date.
- See which weekday you were born on.
FAQ
How is age calculated?
Full years first, then full months, then days. If the day of the month has not come yet, the month is not counted.
What if I was born on February 29?
In years without a leap day, your birthday is counted as March 1.
