How it works
Free date calculator for the exact days between two dates. See the calendar span, elapsed time, weeks, and business days with weekends and your own holiday list excluded. Runs in the browser.
- 01
Enter the start and end
Use calendar dates. Add times when you need hours and minutes, otherwise both start at midnight.
- 02
Choose whether the end date counts
Leave it off for the gap between the dates. Turn it on for an inclusive stay or a business-day count.
- 03
Add holidays if you need business days
One YYYY-MM-DD per line. The business-day total skips weekends and those weekdays.
