Tonight we had to keep an eye on the school's website, to know if school will be open tomorrow or not. It's because Ramadan is about to start, either tomorrow or Tuesday - depending on when they sight the moon - and the day it starts school will be closed.
Well, I just checked, and no moon has been sighted tonight, which means school is on as normal tomorrow, and Ramadan will by default start on Tuesday, whether the moon has been sighted or not. Apparently, they hardly ever sight the moon because of the foggy skies, and the rain; so it almost always starts on the 2nd day they have as an option.
(Some even say it's because the guy who is supposed to look for the moon is half-blind, but I don't know about that! :))
Ramadan ends in a month's time, once again - after they have sighted (or not sighted) the moon, it will end either the 1st or 2nd of October this year. Every year, it comes around slightly earlier than the previous year. You can read more about it here f.e.
