Count working days between two dates — weekends removed, and US federal holidays or UK bank holidays taken out too if you choose.
Holiday dates are calculated from the standard published rules (including US observed days and UK substitute days). Governments occasionally declare extra one-off holidays — treat results as careful estimates for planning, not legal advice.
The calculator walks through every day in your range. Saturdays and Sundays are skipped, and — depending on the mode you choose — public holidays are skipped as well. For the US mode it builds the 11 federal holidays for each year in the range, including observed days (when a holiday lands on a weekend, the nearest weekday becomes the day off). For the UK mode it builds the England & Wales bank holidays, including Easter Monday (worked out from the Easter computus) and substitute days for fixed-date holidays that fall on a weekend.
A business day (working day) is normally a Monday–Friday that is not a public holiday. Weekends and public holidays are excluded.
Yes — choose "US federal holidays" and all 11 are removed, including observed days (for example, when 4 July falls on a Saturday, the Friday before counts as the holiday).
Yes — choose "UK bank holidays (England & Wales)". The standard rules are applied, including substitute days when Christmas Day or Boxing Day falls on a weekend.
By default every day after the start date up to and including the end date is counted — the usual method for deadlines. Tick "Include the start date" if that day should also count.
When a fixed-date holiday falls on a Saturday or Sunday, it moves to the next available weekday — normally the following Monday, or Tuesday if the Monday is already taken. This calculator follows those rules.
They are calculated from the standard published rules. Governments occasionally add one-off holidays, so treat results as careful estimates and check official sources for legal deadlines.
Choose "Weekends only" to count Monday–Friday days with no holidays — that works anywhere in the world.
