Find the gap between any two dates in seconds. Enter a start and end date to see the number of days, weeks, months and years between them.
The calculator converts both dates to a day count and subtracts them, then expresses the gap in days, weeks, months and years. It handles leap years automatically, so the day count is always exact. Order doesn't matter - the result is always positive.
Count down to a deadline, work out a project duration, or find how long ago something happened. If instead you want your age from your birth date to today, our age calculator does exactly that.
