What was the date, years ago?

How the years ago calculator works

Going back a number of years keeps the month and day the same and changes the year. The calculator applies the Gregorian calendar rules, so a start date of February 29 lands on February 28 when the target year isn't a leap year. Everything runs in your browser, nothing is sent to a server.

You can also count in months, weeks, days, hours, minutes, seconds, decades or centuries, measure the gap between two dates, find your exact age, or check whether a year is a leap year.
