San Salvador Day is observed in the capital of El Salvador on August 3. This municipal holiday celebrates the patron saint of San Salvador, the Divine Savior of the World (Jesus Christ), and is part of the week-long August festivals known as Fiestas de agosto. The city of San Salvador was founded in 1525 by Spanish conquistadors and has a rich history, including its destruction by indigenous populations shortly after its founding and subsequent relocations due to seismic activity. San Salvador Day is marked by a large parade and various celebratory events, making it an official non-working day in the city. Notably, the holiday does not coincide with the city's foundation anniversary, which is April 1, but occurs just days before the Feast of the Transfiguration, another public holiday in El Salvador.
