Business days

Business days count Monday to Friday only. Public holidays differ by country, so they are not removed automatically — subtract them yourself if needed.

Including the end date

By default the end date is not counted (1 Jan to 2 Jan = 1 day). Tick Include end date to count both days, as is common for leave and rental periods.
