Questions & answers

Why is October 1 to October 2 one day?

The elapsed difference is one day. The counting range includes October 1 and excludes October 2 by default; including the end date counts both dates.

Can I change weekends?

Choose Monday–Friday, Sunday–Thursday or every day as your working schedule.

Are public holidays automatic?

No. Enter your holiday dates manually so the tool does not assume a country or region.

Do duplicate holidays count twice?

No. Each distinct holiday date is excluded once, and only if it falls on a selected working weekday.

Does daylight saving change the count?

No. These are calendar dates, not elapsed timezone-aware hours.

Can I save the result?

Yes. Download the text result or JSON report, or copy the result. Editing inputs invalidates the previous result until you calculate again.

Is my input uploaded for processing?

Processing runs in a local browser worker with no input upload and no account. Website advertising and analytics are described in the privacy information.
