Whether the end date counts changes the answer by one, and different conventions disagree — notice periods and rental terms usually include it, a simple gap between events usually does not. Public holidays vary by country and often by region, so add your own.

About the Day Counter

Count the days between two dates, either every calendar day or only working days with weekends and holidays excluded. The same span is also expressed in weeks, months, years and hours, and each weekday is counted individually.

Business-day counting is the part that needs care, because whether the end date is included changes the answer by one and different conventions disagree. The calculator states which it is using and lets you switch, so a figure can be matched to a contract or a payroll period rather than guessed at. Custom non-working days can be added, since public holidays differ by country and often by region within one.

Key features of the Day Counter

Business days properly

Weekends excluded, with custom holiday dates you can add for your own country or region.

End date convention stated

Including or excluding the end date changes the answer by one, so both are shown and labelled.

Weekday breakdown

How many Mondays, Tuesdays and so on fall in the span — useful for scheduling.

Every unit at once

Days, weeks, months, years and hours from the same calculation.

Works in both directions

Past or future, and the order of the two dates does not matter.
