Frequently asked questions
Is the end date included?
No. The result counts the days from the start date up to, but not including, the end date. Add 1 to include it.
Are leap years handled?
Yes. Dates are compared on the calendar, so 29 February is counted when it falls in the range.
What if the end date is before the start?
The dates are swapped and the difference is shown as a positive number.
