About working days (weekdays minus holidays)

Payroll, SLA clocks, and school make-up days usually skip Saturday and Sunday. They may also skip public holidays that land on a weekday. This calculator counts every Monday–Friday in the inclusive range, then removes dates you list. It does not know your country’s holiday calendar — you paste those dates. A holiday on Saturday is already a weekend, so excluding it does not change the count; a Friday holiday does.

The range is inclusive on both ends. A Monday-to-Friday week with no holidays is 5 working days. Reverse the dates and the count is the same. We do not skip “half days,” religious observances you did not list, or company shutdowns. Time zones do not apply: the date is a civil date, not a timestamp.

For raw calendar days including weekends, use Days Between Dates. For adding a duration that includes weekends, use Date Calculator. For age, use Age Calculator. Holiday lists never leave the browser.

Working Days Calculator FAQ

Monday through Friday in the inclusive range, on this device’s calendar. Saturday and Sunday never count. Holidays you paste (YYYY-MM-DD, one per line or comma-separated) are removed if they fall on a weekday. A Saturday holiday does not change the total because it was already excluded. A Monday-to-Friday week with no holidays is 5 working days. Reversing start and end does not change the count.

No. Calendars differ by country, region, and company. Paste the extra dates yourself. We do not skip half-days, religious observances you did not list, or shutdowns. The date is a civil date, not a timestamp, so time zones do not apply.
