Business Days Calculator with Public Holidays

Yes. Pick a country or region and the calculator removes its public holidays in addition to weekends. It supports the United States (federal), the United Kingdom (England & Wales, Scotland, and Northern Ireland separately), Canada, Australia, New Zealand, and Ireland. You can also turn holiday exclusion off, or add your own company closure days.

Every holiday is computed from its calendar rule — fixed dates, "nth weekday of the month" rules, and Easter (via the Anonymous Gregorian computus) — including the observed day when a holiday lands on a weekend (for example a US holiday on a Saturday is observed the Friday before, and UK bank holidays get a substitute weekday). One-off holidays set by law, such as the 2022 Platinum Jubilee and the 2023 Coronation, are included too. Nothing is fetched from an external service, so results are instant and work offline.

By default the start date itself is not counted and the end date is included, which matches how most "within N business days" deadlines are read. Use the "Include start date" toggle if your rule counts the first day as day one. Getting this off-by-one right is the most common deadline mistake.

Yes. The working-week selector lets you choose exactly which weekdays count — useful for six-day weeks, Sunday-only weekends, or schedules that treat Saturday as a working day. The calculation and the holiday exclusion both respect your choice.

Yes. When you add or subtract business days, the result includes a one-click download to an .ics file and an "Add to Google Calendar" link, so a deadline goes straight into your calendar. This is something most business-day calculators do not offer.

It matches the standard weekday-and-public-holiday math. Individual couriers, banks, or agencies may also apply their own closure days or cut-off times, and sub-national holidays (individual US states, Australian states, or Canadian provinces) can differ from the national set shown here. Use this for the base calculation, then confirm any organisation-specific rule separately.
