Working Days Calculator
Business days between dates, or a deadline counted in working days.
Count the working days between two dates, skipping the weekend days you choose and any holidays you list. Or flip to the second mode and add a number of working days to a start date, which is how project deadlines and notice periods are usually counted. Public holidays are not built in: every country and employer differs, so you type yours in, one date per line.
Honest limits. Weekend presets describe the usual government working week, not every employer: private companies in the Gulf often work a Saturday to Sunday week even where the government does not, and Sharjah government staff work Monday to Thursday. Public holidays are yours to list because they change every year and differ by country, region and employer; a count without your holidays is a working-week count, not a leave calculation. The add mode counts forward from the day after the start date, so adding 1 working day to a Friday lands on the next working day, not on the Friday itself.
What counts as a working day
A working day is a calendar day that is neither a weekend day nor a holiday you observe. That sounds obvious until you try to count across a month boundary by hand, or across a country boundary: the same two dates give a different answer in Riyadh and in London, because Saudi Arabia's weekend is Friday and Saturday while Britain's is Saturday and Sunday, and because the two countries close for different holidays. The count also depends on a convention people rarely state: whether the end date itself counts. "Days between 1 November and 10 November" usually means 9 days, but a leave form that asks for days "from 1 to 10 November inclusive" means 10. This tool asks you to pick, so the answer matches the form you are filling in.
The add mode answers the other common question: given a start date and a deadline measured in working days, what calendar date is that? Adding 10 working days to a Monday lands on the Friday of the following week, not 10 calendar days later, and a holiday in between pushes it one day further. Notice periods, delivery promises and project plans all use this count, and getting it wrong by a weekend is the most common scheduling mistake there is.
Weekends are not universal
Saudi Arabia moved from a Thursday and Friday weekend to Friday and Saturday in June 2013, with a Sunday to Thursday working week. The UAE federal government moved the other way in January 2022, to a Saturday and Sunday weekend with a four-and-a-half-day week, while Sharjah government staff work Monday to Thursday and take Friday, Saturday and Sunday off. Pick the preset that matches the organisation you are counting for, and check its own calendar when the answer matters.
Why holidays are typed in, not built in
A built-in holiday list would go stale every year and would still be wrong for half its users: Islamic holidays move about 11 days earlier each Gregorian year, national days differ by country, and some employers observe days others do not. Typing your own list takes a minute and is the only way the count can be right for your case.
