What Counts as a Business Day?
A business day (or working day) is normally Monday through Friday, excluding weekends. For most real deadlines it also excludes public holidays, because offices, banks, courts and couriers are closed. This calculator handles both, and lets you set your own working week and closure days when your schedule is different.
As a quick reference, 1 business day is usually the next working day, 5 business days is about one work week, 10 business days is roughly two weeks, and a full year holds around 250 working days once weekends and public holidays are removed.
Why the Holiday Rules Matter
Observed days are handled
When a holiday falls on a weekend, the day off usually moves — a US holiday on Saturday is observed the Friday before, and UK bank holidays get a substitute weekday. Those observed dates are what actually close offices, so they are what the count uses.
Every holiday is shown
Rather than just giving a number, the result lists each public holiday that fell inside your range, with its date. You can see exactly why the working-day count is what it is.
Does the start date count?
"Within 5 business days" can mean day one is today or tomorrow. The include-start toggle lets you match the exact wording of your rule instead of guessing.

Frequently Asked Questions
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.
