Marikina City celebrates its 380th Foundation Day today, April 16, 2010. In line with the city's celebration, a series of activities are set for the annual Ka-Angkan celebration, which is a family reunion of Marikeños nationwide and worldwide. The opportunity is for the current youth to get acquainted with previous generations of relatives and ancestors. There will be 42 clans participating this year. Last year, the 40 clans consisted of over 9,000 members.
On April 17, a foot parade will start at 4 p.m. at the Marikina Sports Park and march to the Riverbanks Amphitheater where there will be a concert and fireworks display. This celebration was initiated in 1998 by former Mayor Bayani Fernando.
