💼 Business Days Calculator
Count Monday-Friday business days between two dates, or work out what date you land on after adding a number of business days — both with an optional holiday list to exclude.
Holidays to exclude (optional, applies to both calculators below)
Blank lines are ignored. Lines that aren't valid YYYY-MM-DD dates are skipped and listed below.
1. Count business days between two dates
| Business days | — |
|---|---|
| Calendar days (inclusive) | — |
| Weekend days | — |
| Holidays excluded | — |
Counts both the start and end date if they themselves are business days (i.e. the range is treated inclusively).
2. Add business days to a date
Negative numbers count backwards (business days before the start date).
| Resulting date | — |
|---|---|
| Day of week | — |
The start date itself is not counted as one of the days added — this answers "10 business days after this date".
