How to count days between dates
Find the difference between two dates in calendar days, weeks, and weekdays.
How to use it
- Choose the start date and end date.
- Enable Include end date when the last day should count as part of the range.
- Review total days, weeks, and weekdays.
Weekdays
Weekdays count Monday through Friday. Public holidays are not removed because holiday calendars vary by country and region.
Inclusive ranges
Some workflows count both the first and last day. Use the include-end-date option when you need that inclusive range.
Local calculation
Date differences are calculated on your device with no upload or remote API.
Date difference FAQ
- What does Include end date do?
- It adds one day to the range, useful when both the start and final day should be counted.
- Does it account for holidays?
- No. It counts weekdays only by day of week, not by regional holiday calendars.
- Can the end date be before the start date?
- Yes. The tool still counts the absolute distance and labels the direction as backward.
