Halloween is not a festival native to the Philippines but is a recent adaptation from American culture, and is usually celebrated in urban areas during the last week of October by throwing Halloween costume parties and letting the children go trick-or-treating. Filipinos in rural areas, however, prefer to observe the more traditional All Saints Day or Undas on the first two days of November. Because of the similarities between the two festivals, Halloween and Undas have come to be linked, and even viewed by some as one celebration. (wikipilipinas)
