US Working Days Calculator — How It Works

Counts the number of working days (Monday to Friday) between two dates.

How it works

  1. Enter a start date and an end date.
  2. The tool counts every day from the start to the end date (inclusive) and tallies how many of those fall on a weekday (Monday through Friday) versus the total number of days.

Formula

Working days = count of Mon–Fri days between start and end date (inclusive)
Total days = end date − start date + 1

Example

From June 1, 2026 to June 30, 2026 (30 total days), there are 22 working days — the rest fall on weekends.

Notes

This calculator counts Saturdays and Sundays as non-working days but does not account for public holidays, which vary by country and region. Subtract any known holidays from the result manually if needed.

FAQ

Yes — the US Working Days Calculator runs entirely in your browser, no sign-up required.

Is this accurate?

The calculator performs the math precisely, but for dates that depend on local rules (holidays, time zone changes, medical estimates), treat the result as a planning guide rather than an official figure.
