Working days calculator

Count working days between dates with your working week and a custom list of holidays.

Enter your values and calculate. Changing an input clears the previous result.

How this calculation works

Counts the selected weekdays and removes only holidays you enter. The start date is included; the end date is optional. Duplicate holidays count once; holidays outside the range or on non-working days do not reduce the total twice. No national holiday calendar is assumed. Limit: 100 years and 366 unique holiday dates.

Worked example

5–9 January 2026, inclusive, contains 5 Monday–Friday working days. Excluding 6 January leaves 4.
