About this tool
Calculate the number of days between two dates with an inclusive or exclusive count, or add and subtract days, weeks, months and years from any date.
How to use it
- Choose “difference between dates” or “add / subtract from a date”.
- Pick the dates or enter the shift, then read the result with the weekday.
- Switch the inclusive toggle when you need to count both start and end days.
Frequently asked questions
Is the end date included?
By default no — the result counts full days elapsed. The inclusive count, which adds one day, is always shown next to it so there is no ambiguity.
