In Saudi Arabia and most Muslim-majority countries, children do not go to school on Sundays. The weekend in Saudi Arabia is from Thursday afternoon until Saturday morning, while Friday is a full-day holiday for Muslims because of the importance of the Jummah prayer, the weekly congregational prayer held on Fridays at noon in mosques.
Therefore, schools operate from Sunday through Wednesday in Saudi Arabia. This arrangement aligns with the religious and cultural practices of the country, ensuring that students and staff have the opportunity to fully observe the weekend and participate in religious activities.
