About this tool
Count business days between two dates, excluding weekends and any custom holidays you add.
Working Days Calculator counts the business days between any two dates, skipping weekends and any holidays you add. You choose which days of the week count as your weekend — Saturday and Sunday, Sunday only, or a Friday-Saturday week — so it works for six-day offices and non-standard rosters too. Alongside the business-day count it reports weekend days, holidays removed, working days per weekday and the total working hours at your chosen hours-per-day.

Set hours per working day and the tool converts the business-day count into total working hours for billing or capacity planning.
The start date is always included if it is a working day. The end date is included by default, and you can switch it off if your range is meant to be exclusive.
It is counted once, as a weekend day. It does not reduce the working-day total a second time, and it is left out of the 'holidays removed' list.
Only India's three fixed-date national holidays — Republic Day on 26 January, Independence Day on 15 August and Gandhi Jayanti on 2 October. Festival dates move each year and state holiday lists differ, so add those manually from your official calendar.
Yes. Deselect Saturday in the weekend picker so only Sunday is treated as non-working, and the count updates immediately.
