The Hijiri new year will be on Saturday according to a circular issued by the Prime Minister.
All ministries, departments and official institutions in the Kingdom will remain closed on Saturday corresponding to Muharram 1.
The day will be compensated by Sunday, as the holiday day falls on a weekly off day.
The occasion marks the arrival of Prophet Muhammad and his followers from Makkah to Madinah more than 14 centuries ago. Known as the Hijrah, this led to the founding of the first Muslim community (umma).
