Marcelo H. Del Pilar Day is observed in Bulacan, Philippines, every August 30 to honor the legacy of Marcelo H. Del Pilar, a prominent Filipino writer, journalist, and lawyer known as the "father of Philippine journalism." Born on this date in 1850, Del Pilar was a key figure in the Reform Movement, advocating for political reform against the Spanish friars' authority in the Philippines. The day is marked by remembrance ceremonies and various activities that celebrate his contributions to journalism and the fight for reform. Del Pilar's activism included founding the nationalist newspaper Diariong Tagalog and later serving as editor of La Solidaridad, both platforms highlighting social and political issues in the Philippines. In addition to the observance in Bulacan, August 30 is recognized nationwide as National Press Freedom Day, reflecting Del Pilar's significant impact on Philippine journalism.
