1 Muharram – Islamic New Year
12 Rabi'-ul-Awwal – Prophet Muhammad's Birthday
27 Rajab – Prophet's Ascension
1-3 Shawwal – End of Ramadan (3 days)
10-13 Dhu al-Hijjah – Feast of the Sacrifice (4 days)

However there are some celebrations with fixed dates in solar calendar for Oman’s population is more open-minded than rest of Islamic world:

January 1 – New Year's Day
July 23 – Renaissance Day
November 18 – National Day
