How Ramadan is importanat for business?

Firstly Ramadan is a holly month in Islam.I watched a video in BBC website about Ramadan. It was very interesting about what Muslims in Ramadan doing. Restaurants, celebration goods and clothes shop are very good business at Ramadan. Many people prefer to eat many kinds of food at night. Finally I would like to say I learned two new words from this video which are fasting and religious.
