Business days calculator
Count the working days between two dates. The calculator treats Monday to Friday as business days, skips weekends, and lets you paste your own list of public holidays to exclude as well — useful for delivery windows, notice periods and payment terms.
How it works
The tool walks from the earlier date to the later date, inclusive of both ends. For each day it checks the weekday: Saturdays and Sundays count as weekend days, weekday holidays you listed are skipped, and everything else counts as a business day. It tallies business days, weekend days and the total calendar days. If you enter the dates in reverse order, it swaps them automatically.
Example
From Monday 1 June 2026 to Friday 12 June 2026, excluding one weekday holiday:
- Calendar days = 12 (inclusive)
- Weekend days = 4 (two Saturdays, two Sundays)
- Holidays on a weekday = 1
- Business days = 12 − 4 − 1 = 7
| Range | Calendar days | Weekend | Business days |
|---|---|---|---|
| Mon → Fri (same week) | 5 | 0 | 5 |
| 1–12 Jun (1 holiday) | 12 | 4 | 7 |
