Questions

How many business days are there in a year?

A year has 260 to 262 weekdays, Monday to Friday. Take out public holidays: in the US, the 11 federal holidays leave about 250; in England and Wales, the 8 bank holidays leave about 252.

Is the start date counted?

By default, no: from Monday to Friday of the same week is 4 business days, as for most deadlines (“within 5 business days”). Tick “Count the start date” to count both dates, as when working out days at work.

Which holidays are included?

US federal holidays, as observed: a holiday on a Saturday moves to the Friday before and one on a Sunday to the Monday after. Or bank holidays in England and Wales, with substitute days when one falls on a weekend. You can add your own dates too, such as company closures or holidays in another country.

How do I add business days to a date?

Choose “Add business days”, pick the start date and type the number of days. The start date is not counted, so 1 business day after a Friday is the next Monday. Type a negative number to count back.

Does it work for a six-day week?

Yes. Tick “Saturday is a working day” to count only Sundays as the weekend.

Are Scotland and Northern Ireland included?

Not as a choice. Their bank holidays differ from England and Wales (for example 2 January and St Andrew’s Day in Scotland, St Patrick’s Day in Northern Ireland). Add them as your own dates.
