Ramadhan is for one month. It is the ninth month of the Arabic calendar.
We fast during Ramadhan from the dawn to the dusk. We are forbidden to eat, drink or consume anything during the day.
At sunset, we break our fast and are free to eat and drink as we please until dawn. (Halal only, of course)
Allah :swt: says:
[2:187]
... And eat and drink until the white thread of dawn becomes distinct to you from the black thread [of night]. Then complete the fast until the sunset. ...
After the month of Ramadhan, we are encouraged to fast for 6 days during
Shawwal, the 10th month of Islamic calendar. These 6 days are
Sunnah, ie it was a customary practice of the Prophet :saws: and he encouraged us to fast them. But they are not obligatory.
Allah :swt: multiplies the reward of each good deed by 10 times. Fasting the month of Ramadhan gives us the reward for fasting 10 months, and 6 days gives the reward of 60 days, ie 2 months, thereby making the rewards of all these fasts as fasting the whole year.
Abu Ayyub (May Allah be pleased with him) reported:
The Messenger of Allah :saws: said, "He who observes As-Saum (the fasts) in the month of Ramadan, and also observes As-Saum for six days in the month of Shawwal, it is as if he has observed As-Saum for the whole year."
[Muslim].
We do not have any special diet during Ramadhan. We simply have to change the times of eating according to the commands of Allah.
As for the closed section for Ramadhan, we have opened some of the sections and the remaining sections are under discussion and we might close one of them for good.
