Simeón Ola Day is observed in Albay, Philippines, every September 2 to commemorate the birthday of Simeón Ola y Arboleda, the last Filipino general to surrender during the Philippine-American War. Born in Guinobatan, Albay, in 1865, Ola became a prominent figure in the fight for Philippine independence, initially joining the Katipunan in the early 1890s. He played a significant role in the Philippine Revolution against Spanish rule and continued to resist American authority after the war. His surrender on July 5, 1901, was controversial, but he is celebrated as a hero in his province. The holiday, designated as a special non-working day by President Rodrigo Duterte in 2018, is marked by remembrance ceremonies honoring Ola's life, service, and bravery.
