Saudi Founding Day (Arabic: يوم التأسيس السعودي), officially the Founding Day (Arabic: يوم التأسيس), is a public holiday in Saudi Arabia celebrated annually on February 22 to commemorate the enthronement of Muhammad bin Saud as the emir of the oasis town of Diriyah in 1727 following the death of his father Saud al-Muqrin, the eponymous ancestor of the al-Saud family. His hereditary succession is considered as the prelude to the inception of the First Saudi State, the antecedent to the Second Saudi State and present-day Kingdom of Saudi Arabia. It was founded in 2022 on its 295th anniversary when King Salman bin Abdulaziz issued a royal decree that designated it as a legal holiday to be observed as per the Gregorian calendar. It is one of the three non-religious national holidays observed in the country, other being the Saudi National Day and Saudi Flag Day.
