Revolution Day, also known as National Day, is a public holiday in Yemen, celebrated annually on October 14th. This holiday commemorates the start of the Yemeni Revolution in 1963 against British colonial rule in Southern Yemen. The revolution led to the establishment of the People's Republic of South Yemen, which later became the socialist state of South Yemen in 1970, and ultimately led to the unification of North and South Yemen in 1990.

Revolution Day in Yemen typically includes various activities such as flag raising ceremonies, military parades, and fireworks. It is also common for speeches or messages to be made by political leaders, including the President. These speeches often reflect on the historical significance of the revolution and the progress that the country has made since gaining independence. Schools and other educational institutions often join in the spirit of the day by hosting programs on the historical significance of the revolution and hosting patriotic events.

This day is a celebration of national pride and identity, and serves as a reminder of the strength and resilience the Yemeni people demonstrated during their struggle for independence. However, it's also a day of reflection and remembrance for those who sacrificed their lives during the revolution. Despite the ongoing conflicts and difficulties that Yemen faces, Revolution Day continues to serve as a symbol of unity and hope, a reminder of Yemen's path to independence and sovereignty.
