The Ka-Angkan Festival kicks off Marikina's festival season. It celebrates the value of kinship and the solidarity of the city's multi-clan makeup. The Ka-Angkan Festival, whose perennial theme is "Ka-angkan ko, mabubuting tao," has a familiar fiesta flavor. Banners, banderitas, and the invigorating sounds of drums and bugles are standard fare, as well as the parade of clans. Members of each clan turn up in huge numbers, proudly proclaiming their "bansag" or special title, be it derived from their clannish occupation, distinct features, traits, or mannerisms. The Ka-Angkan Festival coincides with the celebration of Marikina's founding anniversary on April 16.
