How to use it
- Pick the start and end date. Both are counted unless you untick Count the end date too.
- Add the days off that apply to you: type them in the list (2026-12-24 or 24.12.2026), or pick a date and press Add day off.
- Read the working days, and below them the calendar days, weekend days and the days off that fell on weekdays.
How it counts
Working days are the Mondays to Fridays in the range. Every full week gives 5; the remaining days are checked one by one. Then each day off from your list is subtracted if it falls inside the range on a weekday. A day that is listed twice is counted once, and days off on a Saturday or Sunday or outside the range do not change the result.
There are no built-in public holidays. Holiday calendars depend on the country, often on the state or region, and change every year, so you list the ones you need. Weekends are always Saturday and Sunday.
Worked example
November 2026, from 1 to 30 November with both dates counted:
- 30 calendar days;
- weekends: Sundays 1, 8, 15, 22 and 29 and Saturdays 7, 14, 21 and 28, which is 9 days;
- 30 − 9 = 21 working days.
Add 2026-11-26 (Thanksgiving in the US, the fourth Thursday of November) as a day off: 20 working days.
Tips
- Deadlines in business days. Check whether the day the period starts is itself counted; if it is not, set the start date to the next day.
- Part-time schedules are not covered: the count assumes a Monday-to-Friday week.
- For calendar days, weeks and months between dates, use the days between dates calculator.
