Anniversary of the Declaration of the Unification of Saudi Arabia

Saudi National Day is a public holiday in Saudi Arabia celebrated annually on 23 September to commemorate the proclamation that renamed the Kingdom of Nejd and Hejaz as the Kingdom of Saudi Arabia in 1932 through a royal decree by King Abdulaziz ibn Saud. It was founded in 1965 by King Faisal bin Abdulaziz in order to replace the Royal Seating Day, but at the same time letting it retain its predecessor's year count of 1930 instead of 1932. It was made a public holiday by King Abdullah bin Abdulaziz in 2005 and is one of the three non-religious holidays observed in the country, other being the Saudi Founding Day and Saudi Flag Day.
