Business Days Calculator

Subtract weekday holidays from the Monday-to-Friday count.

Your inputs

Business days

Weekdays minus the holiday count you typed.

The result does not go below zero. The working-days page does not remove holidays.

Assumptions

  • Holidays you enter already fall on a weekday.
  • The page does not look up a holiday calendar.

Worked example

January 1, 2026 through January 31, 2026, after 1 weekday holiday, leaves 21 days.

Input definitions

Weekday holidays
How many Monday-to-Friday dates to remove.

Limitations

A holiday that falls on a weekend should not be included in the count.

Questions

What if I enter more holidays than weekdays?

The result is zero.

Does this know New Year's Day?

No. You type the number of weekday holidays.
