Answer:
Christmas in the Philippines (Filipino: Pasko sa Pilipinas) is one of the biggest holidays in the country. The Philippines, one of two predominantly Catholic countries in Asia (the other one being East Timor), celebrates the world's longest Christmas season,[1][2] with Christmas carols heard as early as September 1 and lasting variously until either Epiphany, the Feast of the Black Nazarene on January 9, or the Feast of the Santo Niño on the third Sunday of January.[3] The official observance by the Catholic Church in the Philippines is from the first day of Advent until the Feast of the Epiphany on the first Sunday after New Year's Day.[4]
Every year, Filipinos from around the world mark September 1 as the beginning of the countdown to Christmas. This countdown, which spans from September to December, otherwise known as the "Ber months", is one of the most important traditions that make the world's earliest and longest timespan of a Christmas season.[5][6][7]
The Christmas season gradually starts from September 1 to December 25 and either ends in January (particularly the third or fourth week of that month) or February.[8] It is celebrated for almost half a year (4 months and 3–4 weeks or 5 months). Generally, holiday decorations are available as early as the weekend of the National Heroes' Day in August. But for the members of the Philippine Independent Church or Aglipayans, Christmas starts on the eve of December 24 and ends on January 1.[9]
