Total calendar days
Count business days between two dates, excluding weekends and holidays.
The business days calculator counts only the working days between two dates, automatically skipping Saturdays and Sundays, and optionally skipping any specific holiday dates you list as well. This is the figure you actually need for anything measured in working time: shipping estimates, notice periods, SLA deadlines, or payroll processing windows, none of which typically count against weekends or public holidays.
A calendar month typically contains eight to nine weekend days that most workplaces don't count toward deadlines. Ignoring that difference means a '10 business day' turnaround can easily stretch to 14 calendar days once two weekends are factored in. This tool walks through every single day in your range, checks whether it falls on a weekend or matches one of your listed holidays, and only counts the days that are left over as business days.
Enter each holiday date in YYYY-MM-DD format, separated by commas, in the same box — for example 2026-01-01, 2026-07-04, 2026-12-25. Any date in that list that falls within your start and end range will be subtracted from the business day total and shown separately in the results, so you can see exactly how many holidays were excluded versus how many were weekend days.
Contract and procurement teams use business day counts to track supplier response windows, HR departments use them for notice periods and probation timelines, logistics teams use them for delivery estimates, and finance teams use them for settlement and clearing periods. Because every industry defines its own holiday calendar, the tool lets you plug in whichever holidays are relevant to your organization or country rather than assuming a fixed list.
Suppose a contract requires a response within '5 business days' of a notice sent on a Thursday. Counting plain calendar days would put the deadline the following Tuesday, but the correct business-day count skips the weekend in between, landing the real deadline a few days later than a naive count would suggest — exactly the kind of mismatch this tool is built to catch before it causes a missed deadline.
Saturday and Sunday are always treated as non-business days. If your organization observes a different weekend (for example Friday-Saturday), list those specific dates in the holiday field instead so they're excluded correctly.
No, the holiday field is optional. If you leave it blank, the calculator will simply exclude weekends and count every other day as a business day.
It's still excluded from the weekend count rather than double-counted, so the business day total stays accurate — the holiday tally only reflects holidays that fell on what would otherwise have been a working weekday.
Yes, there's no limit on the range length; the calculator will walk through every day between your two dates regardless of how many months or years it spans.
No, the tool works with whole calendar days only. Partial-day closures aren't factored into the count.
