Bacolod City Charter Day, observed in Bacolod, Philippines, every June 18, commemorates the day the city was granted cityhood in 1938. This special non-working holiday celebrates Bacolod's rich history, which began as a small coastal settlement named San Sebastián de Magsung̃ay before being relocated to a hilly area and renamed Bacolod in the late 1750s. The city became the capital of Negros Occidental in 1849 and played a significant role during the Negros Revolution in 1898. Bacolod was officially inaugurated as a chartered city on October 19, 1938, with the anniversary of this event marked by the annual MassKara festival in October. The day serves as a reminder of Bacolod's journey from a small settlement to a highly urbanized city and highlights its cultural significance in the region.
