Friday is the holiest day for Muslims. Thus, the weekend in Saudi Arabia was Thursday-Friday. In 2013, the late King Abdullah Al-Saud issued a royal decree switching the weekend to become on Friday-Saturday. This step was taken to reduce the adverse effects suffered by Saudi businesses due to the difference in weekdays and weekends between Saudi Arabia and the other regional and international counterparts. Like all other Muslims, on Fridays Saudis attend Jomua'h prayer that is held by afternoon and accompanied with a sermon.
