Working days between dates calculator
Two dates and a holiday count. Weekends drop out on their own. You type how many of the remaining weekdays are holidays, because this page does not keep a national calendar.
Working days
—
Choose both dates.
Next: Days from today calculatorA date a set number of days away.
Both dates count when they are weekdays. You subtract holidays that fall on a weekday. This page has no national holiday list.
How this is calculated
- Step 1
The span
Both the start and the end are included when they are weekdays.
- Step 2
Weekends out
Saturday and Sunday are removed.
- Step 3
Holidays
You subtract weekday holidays. A Saturday holiday is already out.
Inclusive weekdays minus weekday holidays
working days = weekdays in the inclusive span − holidays
| weekdays | Mondays through Fridays from the earlier date through the later date, both included. |
|---|---|
| holidays | How many of those weekdays are holidays. Do not count a holiday that falls on Saturday or Sunday. |
There is no built-in list of public holidays. A holiday in one country is a working day in another, and the same date moves.
If the holiday count is larger than the weekdays in the span, the working-day result is zero. The page does not invent a negative count.
The plain calendar difference, without weekends removed, is on days between dates.

Are the start and end dates included?
Yes, when they fall on Monday to Friday. A Friday-to-Friday span includes both Fridays. The days-between page’s headline is different: that one is end minus start and leaves the start out.
What should I type for holidays?
The number of public holidays in the span that fall on a weekday. A holiday on Saturday is already excluded with the weekend, so do not count it again.
Why isn’t there a country holiday list?
Lists go stale, and they differ by region. A number you can check against your own calendar stays correct when the official day moves.
Does the order of the dates matter?
No. The earlier date and the later date are sorted. The result says which one came first.
