Provincial Charter Day is a significant holiday in the Philippines recognized in various provinces to commemorate their foundation or the date when they were recognized as a province. It's a local public holiday meaning that people in that specific province will have the day off while the rest of the country goes about their usual business. The exact dates vary greatly from one province to another as there's no 'one-size-fits-all' Charter Day, reflecting the unique history and identity of each province.

Celebrations during Provincial Charter Day are characterized by various festivities that reflect the distinct culture and traditions of the province. These may include colorful parades, fiestas, beauty pageants, street dances, cultural performances, and other community events. It's an opportunity for locals to pay homage to their heritage and to foster community spirit. The day is also often seen as an opportunity to attract tourism and showcase the province's local attractions and delicacies.

Although being a local holiday, it is highly significant to the residents of the province. It's not just about commemorations and merrymaking, Provincial Charter Day is also used as a platform to discuss future plans for the development of the province. Civic leaders and local politicians use the occasion to address their constituents and outline strategic plans. Various recognitions and awards are also given to individuals, organizations, and establishments that have made significant contributions towards the improvement and progress of the province.
