Halloween is a secular holiday combining vestiges of traditional harvest festival celebrations with customs more peculiar to the occasion such as costume wearing, trick-or-treating, pranksterism, and decorations based on imagery of death and the supernatural. The observance takes place on October 31. Halloween was originated in the early Middle Ages as a Catholic vigil observed on the eve of All Saints Day (also known as "All Hallows Day"), November 1.
Though it was regarded up until the last few decades of the 20th century as a holiday primarily for children, in more recent years Halloween activities such as mask wearing, costume parties, themed decorations, and even trick-or-treating have grown popular with adults as well.
For us Filipinos, we are not so particular in holding Halloween party. We give importance in celebrating the All Saints Day and All Souls Day wherein people are going to the cemetery and offer prayers to the dead love ones and friends.
