Working Days Calculator

From-date and to-date in, weekday count out — plus the calendar-day totals.

The widget below counts Monday-through-Friday dates between (and including) any two endpoints. It does not subtract national or religious holidays — those vary by country and region too widely to ship a single correct list. The tool is the right answer for contract durations, deadline countdowns, and the rough length of a working leave; for an exact holiday-adjusted count, look up your country’s official calendar.

Both endpoints are counted. Public holidays are not subtracted — for a holiday-aware count, look up your country’s official calendar and deduct manually.

How to use

  1. Pick the start date

    Both endpoints are counted. Setting both fields to the same Monday returns 1 weekday.

  2. Pick the end date

    Order doesn't matter — flipping the dates flips the sign. Useful for backward-looking accruals.

  3. Read all three counts

    Working days is the headline. Total calendar days and weekend days are surfaced so you can sanity-check that the math adds up.

Frequently asked questions

Are public holidays subtracted?
No. Holidays differ by country, region, religion, and year — there is no single correct set. For the cases that need them, look up your jurisdiction's official calendar (UK: GOV.UK; US: OPM; Turkey: T.C. Resmî Gazete) and deduct manually.
How are partial weekends handled?
A range that starts on Saturday and ends on Sunday returns 0 weekdays. A range starting Friday and ending Monday returns 2 (Friday + Monday).
Does it work for very long ranges?
Yes — the calculator iterates day by day. A 100-year range completes in milliseconds.
Is the count inclusive of both endpoints?
Yes. From Mon May 11 to Fri May 15 returns 5 weekdays. If you need 'business days from now', use a start date of tomorrow and an end of the deadline.
What if the range is backward?
The count becomes negative — useful when you want to know 'how many working days ago was this'. The absolute value is shown in the headline; the sign appears as 'reverse range'.
Are leap days counted?
Yes. Feb 29 in a leap year is counted normally if it falls between the two dates.

About

Why an extra 'inclusive' decision matters

Different tools count differently. Excel's NETWORKDAYS() is inclusive of both endpoints (matches this tool). Date-fns's differenceInBusinessDays() is exclusive of the start date. For contractual durations always read the exact wording — 'from May 1 to May 5' can mean 4 or 5 days depending on the contract.

Practical patterns

Maternity leave duration, project schedule estimates, paid-time-off accrual, lead-time guarantees, and the implicit '5 business days' on customer-facing emails. Pair this with a holiday list for jurisdictionally-accurate answers.
