Questions

Is the end date included?

Not by default: from Monday to Friday is 4 days, as most people count a period of time. Tick “Include the end date” to count both days, which gives 5. That’s how you count days of a holiday or a hotel stay with the checkout day included.

How are months counted?

By calendar months from the start date, with the leftover days after the last whole month. Adding a month to 31 January gives 28 or 29 February, the last day of the shorter month, as most calendar apps do.

Are public holidays excluded from weekdays?

No. Weekdays are Monday to Friday, without holidays, which differ by country and region. For working days without your holidays, use the Business Days Calculator.

Does daylight saving time affect the result?

No. The calculator works with whole calendar days, so clock changes never shift a result by an hour or a day.

Is it free? Do I need an account?

It is free to use and there is nothing to sign up for. There are no watermarks and no daily limits.
