Business Days Calculator

Count how many Mondays through Fridays sit on the calendar from the earlier date through the later date, both ends included. Saturday and Sunday are dropped. Public holidays are not — a Wednesday bank holiday still counts here.

How to use

  1. Pick a start date and an end date. Order does not matter; the earlier date is used as the start of the range.
  2. Read weekdays (Mon–Fri) as the business-day count, plus how many weekend days fell in the same inclusive span.
  3. If a holiday sits on a weekday, subtract it yourself. This page has no holiday calendar.
  4. For elapsed calendar days including weekends, use Days Between Dates instead — that tool is a duration, not an inclusive weekday tally.

How it works

A “business day” on this page means a Monday, Tuesday, Wednesday, Thursday or Friday that appears in the inclusive range. Monday 1 January 2024 through Friday 5 January 2024 is five weekdays and zero weekend days. Friday 5 January through Monday 8 January is two weekdays (Friday and Monday) and two weekend days (Saturday and Sunday). A range that is a single Monday is 1; a range that is a single Saturday is 0.

Inclusivity is the usual source of disagreement with Days Between Dates. That tool reports elapsed midnights: Friday to Monday is 3 calendar days. This tool lists the dates that exist from Friday through Monday and keeps only weekdays, so the answer is 2. Neither figure is “wrong”; they answer different questions. Contract language that says “within five business days” usually wants this inclusive weekday count — and then still needs a human to remove holidays.

Holidays are the hard limit. New Year’s Day, Christmas, regional saints’ days, company shutdowns and substitute Monday holidays are invisible. If 1 January is a Monday, it still increments the business-day total. There is no country picker and no observed-holiday table. Treat the result as “weekdays on a blank calendar,” then subtract the closures you actually observe.

Sweden’s Lag (1989:253) om allmänna helgdagar names the public holidays. Sundays are already outside this count, and in that statute midsommardagen and alla helgons dag fall on a Saturday. The days that can still inflate a weekday total are the ones that land on Monday–Friday: New Year’s Day, Epiphany (6 January), Good Friday, Easter Monday, 1 May, Ascension Day, National Day (6 June), Christmas Day and Boxing Day. Finland keeps its own list. On Åland, Autonomy Day (9 June) is a local closure this page does not know. Subtract those weekday closures yourself.

Date order is normalized. Swapping the two fields does not change the count. The page also reports weekend days and the inclusive calendar length so you can see how much of the span was Saturday or Sunday. It does not know half-days, shift patterns, or jurisdictions that treat Friday–Saturday as the weekend.

This is not a payroll engine and not legal advice. Some statutes define business days with holiday lists and notice-by-close-of-business rules. Those extras are outside the calculator. For full weeks of seven calendar days, use Weeks Between Dates. For a date N weekdays away, this page still will not skip holidays on the walk.

Formula

Business days = count of Mon–Fri dates from start through end (inclusive)

Worked examples

  • A working week

    2024-01-01 (Mon) to 2024-01-05 (Fri) → 5 weekdays, 0 weekend days

  • Friday to the following Monday

    2024-01-05 to 2024-01-08 → 2 weekdays, 2 weekend days

Useful notes

  • Public holidays are not excluded — only Saturday and Sunday. Swedish weekday helgdagar, Finnish public holidays and Åland’s Autonomy Day (9 June) still count until you subtract them.
  • Both endpoints count when they fall on a weekday. That is not the same as elapsed days.
  • Reversing the two dates does not change the result.

FAQ

Are public holidays excluded?

No. Only Saturday and Sunday are skipped. A Wednesday holiday still counts as a business day here.

Does the range include both dates?

Yes. The start and end dates are both counted when they fall on a weekday.

What if I reverse the dates?

The same span is counted. The tool always uses the earlier date as the start of the range.

Does a Friday-to-Monday span count as one business day or two?

Two, if both Friday and Monday are in the inclusive range. Saturday and Sunday are weekend days. Days Between Dates would call the same pair 3 elapsed calendar days.

Can I exclude my country’s holidays?

Not automatically. Subtract weekday holidays yourself. In Sweden, Sundays are already excluded, and midsommar and All Saints fall on Saturday, so the ones to check are the named days that land on Monday–Friday. Finland and Åland are separate lists, including Åland’s Autonomy Day on 9 June.
