Pangasinan Day, observed in the Philippine province of Pangasinan, recurs every April 5 as a special non-working holiday to commemorate the province's founding anniversary. The holiday celebrates the rich cultural heritage of Pangasinan, which is home to the indigenous Pangasinan and Sambal peoples, as well as the Ilocano settlers. The province's name translates to "place of salt," reflecting its historical significance in salt production and trade, which dates back to the Austronesian expansion. The first celebration of this anniversary took place in 2010, and in 2019, the holiday was officially recognized by President Rodrigo Duterte. Festivities typically include cultural performances, food festivals, concerts, and a pageant, showcasing the province's vibrant arts and traditions. Notable attractions in Pangasinan, such as the Hundred Islands National Park, further highlight the region's appeal.
