Workday Calculator: Count Working Days Without Weekends
Use a workday calculator to count Monday-Friday days between dates, subtract holidays, and avoid the off-by-one mistake when both dates should count.
What a workday calculator counts
A workday calculator counts weekdays between two dates: Monday, Tuesday, Wednesday, Thursday, and Friday. It skips Saturday and Sunday. If a holiday falls on a weekday, subtract it separately unless your policy treats that holiday as a working day. The Business Days Calculator has a holiday field for exactly that.
The inclusive-date choice
Most everyday workday counts include both ends. Monday to Friday is 5 workdays, not 4. Monday to the following Monday is 6 workdays. If a rule says counting starts "after" a date, then the first date may be excluded. Keep that assumption out in the open because one missed date changes payroll, PTO, and deadline totals.
Subtract holidays only when they are weekdays
Do not subtract every holiday automatically. If a holiday lands on a Saturday or Sunday, it is already outside the weekday count. Only subtract holidays that fall on Monday through Friday and are actually excluded by your workplace or deadline rule.
When this is the wrong tool
Use a workday calculator for date spans, not shifts. If you need 8:15 AM to 5:00 PM minus lunch, use the Hours Calculator. If you need a full weekly timesheet, use the Time Card Calculator. Date math and clock math answer different questions.
Frequently asked questions
Count Monday through Friday dates in the range, usually including both the start and end date. Skip Saturdays and Sundays, then subtract weekday holidays if the rule excludes them.
If both dates count, Friday to Monday is 2 workdays: Friday and Monday. Saturday and Sunday are skipped.
Usually no for federal offices, but private employers and contracts can define holidays differently. Subtract only holidays that apply to the rule you are using.
No. It counts dates. Use a time card or hours calculator for clock-in and clock-out time.
