DETAILS
Date difference method
The tool calculates the exact calendar-day gap between two dates and also presents the interval in weeks, months, and years for easier comparison.
Example use
Compare a departure and return date or a contract start and end date to see the total interval at a glance.
Good to know
If both the start and end dates must be counted, an inclusive period may be one day longer than the displayed date difference.
Frequently asked questions
What happens when both dates are the same?
The difference is zero days. Count it as one day only when you need an inclusive period.
Why do month totals not map to a fixed number of days?
Calendar months vary from 28 to 31 days, so months are not a fixed-duration unit.
