How Oman working days are counted

From 28 June 2013, Oman moved its public-sector weekend from Thursday-Friday to Friday-Saturday by Sultani Decree, aligning with global capital markets. This calculator counts every Sunday through Thursday as a working day and excludes Friday and Saturday. Public holidays you specify are deducted on top.

Oman typically observes 12-14 paid public holidays a year. Several are tied to the Hijri calendar (Eid Al Fitr, Eid Al Adha, Hijri New Year, Prophet's Birthday) and confirmed close to the date by moon sighting - so a static holiday list is unreliable. Enter the count for your specific window.

Worked example

From 1 to 30 April 2026 there are 30 calendar days. The window contains 8 weekend days (4 Fridays + 4 Saturdays) and, for example, 2 public holidays (Eid Al Fitr). Working days = 30 − 8 − 2 = 20 days.

Quick formulas

Calendar days = inclusive count from start to end.
Weekend days = count of Fridays and Saturdays in the range.
Working days = calendar − weekend − public holidays.

Frequently asked questions

What is Oman weekend?
Friday-Saturday for most of the federal sector since 28 June 2013. Some private firms still use Sat-Sun or Fri-Sat.
How many Oman public holidays per year?
Roughly 8-10 including Eid Al Fitr (3-4d), Eid Al Adha (3-4d), Oman National Day 23 Sep, and Founding Day 22 Feb. Oman does not officially observe Hijri New Year, Prophet's Birthday, or Western New Year.
Why enter holidays manually?
Several Oman holidays are confirmed by moon sighting just before the date, so any static list goes stale.
Are half-day Fridays counted?
Friday is treated as non-working here. Adjust the holiday count if your firm works half-day Fridays.
Does this match Microsoft Excel's NETWORKDAYS?
Yes - with the weekend set to Fri-Sat. Excel's default Sat-Sun gives different results.
