In Indoneisa, we have been in Ramadan period from mid-June to mid-July.
As you know, most of muslim people do fasting during daytime, and then they have a break fasting at the evening time after sundown.
Generally speaking, in the most of companies in Indonesia, people leave their office earlier than usual e.g. 4pm, because of that, sometimes the work task would have been delayed.
But in my company, the meals for break fasting have been supplied to all the employees, so my colleages continue to work after taking their break fasting. That's why our office is still busy even after evening time in Ramadan period.
