About this calculator

Counts weekdays (Mon-Fri) excluding US federal holidays between two dates, inclusive of both endpoints. US federal holidays for 2024-2030 are hardcoded (movable holidays computed correctly). For different country holidays, set the toggle to "no".

Frequently asked

Is the count inclusive?+
Yes — both start and end day count if they are business days.
Which holidays are excluded?+
11 US federal holidays: New Year's, MLK, Presidents, Memorial, Juneteenth, Independence, Labor, Columbus, Veterans, Thanksgiving, Christmas.
What about state-specific holidays?+
Not included. Add them manually if your state observes them differently.
Half-days?+
Not modeled — every weekday counts as 1, holidays as 0.
How does this differ from days-between-dates?+
days-between-dates counts every calendar day. This counts only Mon-Fri non-holiday workdays.
