Days Between Dates Calculator
Calculate the number of days, weeks, months and years between any two dates. Also shows working days and weekends separately.
How many days until Christmas? How many working days between now and a deadline? How many days have passed since a specific event? Enter any two dates to find out.
How to Calculate Days Between Two Dates
The simplest method is to subtract the earlier date from the later date. Most programming languages handle this natively. Mentally, you can count forward month by month, adding the days in each month (accounting for leap years in February).
Working days exclude Saturdays and Sundays. Public holidays are not excluded in this calculator as they vary by country and region.
Frequently Asked Questions
Does this calculator include the start and end dates?
This calculator counts the number of days between the start and end date, not including the start date itself. For example, from January 1 to January 3 is 2 days (the 2nd and 3rd). If you need to include both endpoints, add 1 to the result.
How do I calculate working days only?
Working days (also called business days) exclude Saturdays and Sundays. This calculator automatically provides a working days count. Note that public holidays vary by country and are not excluded — you would need to manually subtract any holidays that fall within the date range.
