In Reply to: When is Ramadan? Think in November posted by jono on Sunday, 10. April 2005 at 13:46 Bali Time:
Ramadan won't affect anything, as it's not when businesses close. It's Idul Fitri, which is the end of Ramadan, when they go home to visit families, and non-Muslim Indonesians go on holiday.
From what I can find, it's November 3-4 2005.
