Navotas Day, also known as the Pangisdaan Festival, is observed in the Philippine city of Navotas every January 16 to commemorate its founding anniversary. This highly urbanized city, part of Metro Manila, celebrates its rich history, which dates back to its separation from Malabon in 1859. The festival, which has been celebrated since the early 2000s, is named after the word "isda," meaning "fish," reflecting Navotas's reputation as the Fishing Capital of the Philippines and its status as the largest fishing port in Southeast Asia. The Pangisdaan Festival features a week-long series of events culminating on January 16, including a thanksgiving mass, sports competitions, boat racing, live concerts, a street dance contest, and a grand parade. The festival highlights the city's vibrant culture and community spirit, bringing together residents and visitors alike to honor Navotas's heritage and economic significance in aquaculture and fishing.
