I’m often asked for a schedule of Greenbelt Mass celebrations by my friends as I’ve saved the times on my cellphone. Sharing it with you too in case you find yourself in the area and and decide to hear Mass:

Monday to Friday: 7.15 am, 5.45 pm, 7 pm
Saturday: 12.15 pm, 4.30 pm, 6 pm
Sunday: 7.15 am, 9 am, 10.30 am, 12 pm, 3 pm, 4.30 pm, 6 pm, 7.30 pm

They may change without notice. Weekend noontime and early evening masses are always full, with people spilling over to Greenbelt 4. It’d be best to come early so you can get a comfortable seat inside the chapel.
