How it works
This counts calendar days from the start date through the end date, inclusive of both, and classifies each one as a weekday (Monday-Friday) or a weekend day (Saturday-Sunday). The business-day count is purely calendar math — no public holidays are subtracted, since which days are holidays depends on country, region, and industry, and this site never hardcodes that kind of fact (it would only ever go stale).
Internally, the range is split into whole 7-day weeks (each contributing exactly 5 weekdays) plus a short remainder of fewer than 7 days, and only that remainder needs its individual weekdays checked — an equivalent but faster route to the same count as checking every single day.
FAQ
Does this subtract public holidays?
No. Holiday calendars vary by country, region, and even employer, and change from year to year, so this calculator sticks to pure Monday-Friday weekday counting. If your date range includes holidays, subtract those manually from the result.
Are the start and end dates both counted?
Yes — this counts an inclusive range. If the start date is a Monday and the end date is that same week's Friday, that's 5 business days, not 4.
