Manila Day, celebrated every 24th of June, is a special non-working holiday in the capital city of the Philippines – Manila. This holiday pays homage to the foundation of Manila by Spanish navigator Miguel López de Legazpi in 1571, marking the city's rich historical significance. Festivities held during this day often include historical and cultural activities, showing the vibrant colors of Manila's past, present, and future.

Prior to its establishment by the Spaniards, Manila was a Muslim settlement headed by local chieftains. With the arrival of Miguel López de Legazpi, it was proclaimed a city and became the center of Spanish power in the Far East. Throughout its history, Manila has been the site of significant historical events that shaped the Philippines. It was a capital under the Spanish, American, and Japanese regimes, survived catastrophic events such as the Battle of Manila during World War II, and is now a bustling metropolis.

On Manila Day, people often remember the historic and cultural significance of the city. Several activities are held, such as parades showcasing Filipino creativity and resilience, historical re-enactments, and special masses. Schools and government offices within Manila are closed, giving the residents an opportunity to celebrate their identity and history. Although this holiday is specific to Manila, the rest of the nation recognizes the importance of their capital's history and contribution to the country's growth and transformation over the centuries.
