Days between dates: common questions
Are public holidays excluded from working days?
No, only Saturdays and Sundays are removed. Subtract any public holidays in the range yourself.
How do I count down to a date?
Leave the start date as today and enter the day you are waiting for as the end date. The result is the number of days left.
What if I enter the dates the wrong way round?
It does not matter; the earlier date is treated as the start.
