Determine the number of working business days between any two calendar dates. Automatically separates Saturdays and Sundays and accounts for optional public holidays for accurate project planning.
Runs entirely in your browser
Project timelines, notice periods and service-level agreements are usually measured in working days, not calendar days — and the difference adds up quickly once weekends and holidays are involved. This calculator counts the business days between two dates, automatically excluding Saturdays and Sundays, with the option to also exclude public holidays you specify.
That makes it far more accurate than counting calendar days for anything scheduled around a working week. A two-week window that spans a public holiday and two weekends is noticeably shorter in working days, and knowing the real figure prevents deadlines that quietly slip.
It runs in your browser, so you can plan schedules without sending your dates anywhere. Use it to estimate delivery dates, work out a genuine deadline from a “within N business days” promise, or count the working days in a project phase.
