Manila celebrates civic and national holidays. Since most of the city's citizens are Roman Catholics as a result of the Spanish colonization, most of the festivities are religious in nature. Manila Day, which celebrates the city's founding on June 24, 1571, by Spanish ''conquistador'' Miguel López de Legazpi, was first proclaimed by Herminio A. Astorga (then Vice Mayor of Manila) on June 24, 1962. It has been annually commemorated under the patronage of John the Baptist, and has always been declared by the national government as a special non-working holiday through Presidential Proclamations. Each of the city's 896 barangays also have their own festivities guided by their own patron saint.
