Most of the Muslim world started fasting the month of Ramadan on Thursday. Ramadan is the ninth month in the Islamic lunar calendar, during this month Muslims abstain from eating and sex, among other things, before sunrise until sunset.
In reality, abstaining from food is the easy part. The aim of Ramadan is for the Muslim to be able to control all his/her desires and behaviours. So if you use to eat too much or sleep too long, you can readjust in this month. If you had anger problem, didn't have time to connect with friends, then you should do that in Ramadan. Also, Muslims should be more charitable in Ramadan, being hungry should remind you that others aren't as fortunate as you're.
But Ramadan has been mixed with culture, and has been almost entirely changed to a cultural event. People pray less, eat more and often times end up worse than they were before Ramdan(I've been guilty of that before).
During the month, I'll post on some of the more notable intersections between the cultural-ramadan and the real-ramadan.
