I am currently in Indonesia/Java and the muezzin/minaret/mosque calls go on for much longer than what I've experienced before. I've been to a couple of Muslim countries and they've done the calls 5 times a day, couple of minutes and that's that.
But here it's 21:03, I have checked the prayer times and the last one was more than two hours ago. The call is still going on. It's currently Ramadan, can it be due to that? And what is the content of the call?
