National Heroes’ Day is observed in the Philippines on the last Monday of August to honor the country's heroes throughout its history, particularly commemorating the beginning of the Philippine Revolution. This holiday marks the Cry of Pugad Lawin, which occurred on August 23, 1896, when Andrés Bonifacio and the Katipunan revolutionary society initiated a revolt against Spanish colonial rule. Established in 1931, the day recognizes heroes who do not have their own holidays, with nine historical figures officially designated as national heroes by the National Heroes Committee in 1995, including Andres Bonifacio, Jose Rizal, and Gabriela Silang. Celebrations typically include wreath-laying ceremonies, parades, and local firework displays. As a public holiday, it is a non-working day for most Filipinos, allowing them to participate in the festivities and reflect on the contributions of both known and unknown heroes.
