This weekend marks the start of the ninth month of the Islamic calendar, and Muslims all over the world will observe Ramadan – a month of obligatory fasting and forgoing liquids and sexual relations from dawn until dusk.
The observance of Ramadan is one of the five core pillars of Islam and this year's Ramadan will begin on the evening of the 28 June in the UK, depending on the sighting of the new crescent moon, and end on the evening of 28 July.
The word "Ramadan" is derived from an Arabic word for intense heat, scorched ground and shortness of food and drink. It is considered to be the most holy and blessed month in the Islamic calendar. Here's a look at the ways people are preparing for Ramadan now and how they observed it last year:

During Ramadan, it is common for Muslims to have one meal in the evening when the sun sets, which is known as "Iftar". Early in the morning around 4-5am, they will have another meal before the sun rises, known as "Suhoor".
