Independence Day in Peru is celebrated every July 28 and is the most important public holiday in the country. It commemorates the day in 1821 when Peru declared its independence from the Spanish Empire, a milestone achieved with the help of Spanish-Argentine general José de San Martín. The festivities last for two days, with July 28 dedicated to celebrating independence and July 29 honoring the Armed Forces and the National Police of Peru. The celebrations begin at dawn with a 21-cannon salute, followed by a Mass of Te Deum and an Address to the Nation by the President. Informal festivities include folk music, dancing, parades, and fireworks, while the highlight of July 29 is the Great Military Parade in Lima, showcasing the Peruvian Armed Forces and National Police. Throughout July, the national flag is prominently displayed in homes and institutions, symbolizing national pride.
