About this date difference calculator
Counting days across month boundaries by hand is error prone. This tool gives the exact gap between two dates, plus a working-days count that skips weekends.
It also runs in reverse: add or subtract a number of days from a starting date to find the resulting date.
How to use it
- Enter a start date and an end date.
- Read the difference in days, weeks, months and years.
- Switch to the Add/Subtract tab to shift a date by a number of days.
Date Difference Calculator — FAQ
Does the count include the end date?
The main figure is exclusive of the end date; an inclusive count is shown alongside it.
Are public holidays excluded from business days?
No — only Saturdays and Sundays. Holidays vary too much by country to assume.
