How we calculate
- Counts whole calendar days, midnight to midnight, in your local timezone.
- Counting is exclusive: today is day 0 and is not counted.
- Business days are Monday–Friday by default (other working weeks are selectable where offered). The holiday-aware result skips public holidays only for the holiday calendar you choose in the calculator: United States, United Kingdom (England & Wales), United Kingdom (Scotland), United Kingdom (Northern Ireland), Ireland, France, Canada, Australia, and Uganda, or your own custom list. There is no default calendar; each result names the one used and lists the excluded days.
- No login and no server: every result is computed in your browser, so you can verify it yourself.
