Working Days Calculator
Business days between two dates, excluding weekends and Pakistan's fixed-date public holidays
Frequently Asked Questions
Calculating business days between two dates — excluding weekends and Pakistan's fixed-date public holidays — requires more than simply subtracting calendar days and estimating a weekend deduction, since holidays add an additional exclusion layer beyond weekends alone, and getting an accurate count matters directly for business deadlines and delivery estimates.
Why weekends alone don't capture the full working-day exclusion
A rough estimate of working days might account for weekends by assuming roughly 5 out of every 7 days are working days, but that approximation misses public holidays entirely — Pakistan's fixed-date public holidays (holidays that fall on the same calendar date every year, as opposed to holidays whose date shifts, like those tied to the Islamic lunar calendar) need to be explicitly excluded in addition to weekends for an accurate working-days count. Skipping the holiday exclusion overstates the actual number of working days in any date range that happens to include one or more public holidays, and the size of that overstatement compounds the more holidays fall within the specific range being calculated.
A worked example
A date range that happens to include a public holiday will have fewer actual working days than a same-length date range without a holiday in it — a working-days calculation that accounts only for weekends (ignoring the holiday) would report the same working-day count for both ranges, when in reality one range has one fewer actual business day available.
How this connects to your other date and time calculations
This calculator's underlying weekday-counting logic is shared with the Date Difference Calculator's weekday/weekend breakdown feature — the working-days calculator extends that same weekday-identification logic with the additional public-holiday exclusion layer specifically relevant for business and payroll date calculations.
Common mistakes
Estimating working days using only a weekend-proportion approximation (roughly 5/7 of total calendar days), without separately checking for and excluding public holidays that fall within the specific date range, overstates the true working-day count whenever the range includes one or more holidays — for any calculation where an accurate working-days figure genuinely matters (a delivery deadline, a project timeline), explicitly excluding holidays rather than relying on a weekend-only approximation avoids that overstatement.
