Simbang Gabi officially starts on Saturday, December 16. It is a Filipino Catholic Christmas tradition in which devotees attend nine masses daily until Christmas Eve. Many Catholics believe that if they go to mass for nine days, their wishes will be granted. In some churches, the mass starts as early as 3:00 AM to 5:00 AM.
