How to use the Date Calculator

Choose two dates to measure the interval, or enter a number of days to calculate a new date.

How it works

The date calculator measures whole calendar days between two dates and can add or subtract a chosen number of days from a base date.

Example: Dates 30 days apart are displayed as 4 weeks and 2 days. Entering −14 in the offset field returns the date two weeks before the base date.

What to keep in mind

The interval is calculated between the selected calendar dates. It does not currently exclude weekends or public holidays.

Frequently asked questions

Is the end date counted inclusively?

No. The result is the elapsed interval between the two dates. Add one if you need an inclusive count.

Can I subtract days?

Yes. Enter a negative number in the days field.
