National Heroes Day is a legal holiday here in the Philippines. We celebrate it to commemorate all other unsung heroes who don't have their own legal holiday. It was declared a national holiday that fall every last Sunday of August by virtue of Act No. 3827 of 1931. August was the month chosen so as to remember the Cry of Pugad Lawin by the Katipunan led bythe "Supremo" Andres Bonifacio.
It is now celebrated on this day, last Monday of August 2009.
