Business days calculator: Oman
Add working days to a date or count working days between dates in Oman, using the real public-holiday calendar (15 holidays in 2026) and the correct weekend (Friday and Saturday).
Note the weekend: in Oman the weekend is Friday and Saturday. Deadline code that assumes a Saturday and Sunday weekend lands one or two days wrong here.
A few dozen free calculations a day. Need this in code? The API answers the same questions in one GET request, and the playground covers the fancier ones: due dates, paydays, bridge days.
