Simbang Gabi is a nine-day series of pre-dawn Masses in the Philippines from December 16 to 24, honoring the anticipation of Christ's birth.
Simbang Gabi, known as the Night Mass, is a devotional practice observed in the Philippines from December 16 through Christmas Eve. Participants attend early morning Masses, often held before sunrise, as an act of faith and anticipation of Christ's birth. The tradition dates to Spanish colonial times when farmers and fishermen began their day early, making dawn services more accessible. After Mass, communities share festive treats such as bibingka (rice cakes) and puto bumbong (purple rice delicacy) served from outdoor stalls. Many faithful ring church bells or carry lanterns in procession to the church grounds, creating a luminous and joyous atmosphere. Completing all nine Masses is believed to grant special petitions or blessings. Simbang Gabi highlights community solidarity and deep cultural roots, blending religious devotion with Filipino hospitality and culinary heritage.
