Working Days Calculator

Business days between dates, custom weekends.

Count the working days between two dates with the weekend you actually have — Saturday and Sunday, Friday and Saturday, Sunday only or any custom mix — and subtract your own list of public holidays.

How to use

  1. Pick the start and end dates.
  2. Select your weekend days.
  3. Paste any holidays as dates (YYYY-MM-DD).
  4. Choose whether the end date counts.

Example

From Monday 5 October to Friday 30 October 2026 with a Saturday–Sunday weekend there are 20 working days, including both ends.

Good to know

  • Public holidays differ by country and change each year, and some depend on moon sighting — enter the dates that apply to you.
  • A holiday that falls on a weekend isn't subtracted twice.

Frequently asked questions

Are the start and end dates included?

Both are included by default. Untick “Include the end date” to count up to, but not including, the end date.

Can I use a six-day working week?

Yes. Select only Sunday (or only Friday) as the weekend.

Does it know public holidays?

Not automatically, because they vary by country, region and year. Add them yourself for an accurate count.
