FAQ
Does the day count include the end date?
By default the end date is excluded (Jan 1 → Jan 2 counts as 1 day). Tick “include end day” to count both boundary days — useful for event, rental or leave durations.
How are business days calculated?
Business days count Monday–Friday only and skip weekends. Public holidays differ by country, so they are not subtracted.
Are leap years handled correctly?
Yes — the calculator works on real calendar dates, so February 29 and varying month lengths are counted exactly.
