Frequently asked questions

How are the days between two dates counted?

The tool subtracts the start date from the end date, so 1 October to 31 October is 30 days. Working days are different: they count both the first and the last date.

What is the weekend in Saudi Arabia?

Friday and Saturday for government and most private companies. You can switch to Saturday and Sunday.

Are public holidays removed from working days?

No. Only the weekend you choose is removed. Subtract public holidays yourself.

How do I go back in time?

In “Add or subtract days”, enter a negative number such as -30.

Are notice periods counted in working days?

Many labour periods are counted in calendar days, not working days. Check your contract and the Labour Law before relying on a count.

Does it show the Hijri date too?

Yes. When you add or subtract days, the result shows the Gregorian date, the day of the week and the Hijri date.
