The Restoration of the State Day, also known as Lithuanian Statehood Day, is a significant public holiday in Lithuania. This national holiday is observed annually on February 16th. It commemorates the reestablishment of Lithuania's independence from the Russian Empire. The day marks the signing of the Act of Independence of Lithuania by the Council of Lithuania, a group of twenty men, on February 16, 1918.

The day is celebrated throughout Lithuania with various activities. These range from concerts, parades, fireworks, to even grand state ceremonies. Schools, businesses, and government offices are closed on this day, giving everyone an opportunity to partake in the festivities. A symbolic gesture of this celebration is the hoisting of the country's national three-colour flag on homes and other major public buildings.

The holiday serves as a reminder of Lithuania's struggle and resilience in maintaining its sovereignty. Even though the independence of the state was crushed during World War II, the February 16th celebration symbolizes the Lithuanian people’s unwavering desire for freedom. It is fundamentally a day to celebrate the unity and legacy of the Lithuanian State and is held close to the hearts of the people there.
