Calculating the number of days between two dates
To find the gap between two dates, just pick a start date and an end date. The calculator shows the number of days, weeks and months, and the number of working days (Monday to Friday). Tick “Count the end day too” to include both ends.
Countdowns, notice periods, deadlines
This tool helps work out a notice period, a cooling-off period, the time left before an exam, a trip or a birth, or the length of a contract. Public holidays are not deducted from working days: remove them by hand if your deadline excludes them.
Add or subtract days from a date
The second part of the page gives the date you get by adding or subtracting a number of days: useful for a 30, 60 or 90-day deadline, or to find a start date.
