Ramadan sees Muslims take part in a period of fasting, in which they will not eat or drink before dawn or after sunset for a month.
The fasting is designed to allow Muslims to concentrate on their faith and devotion to Allah.
The only times during this periodMuslims are allowed to eat ise before daybreak and after sunset.
A meal named the Suhoor is eaten before daybreak, and a meal called the Iftar will be partaken immediately after sunset.
When does Ramadan end this year?
Ramadan officially began on May 16 this year, and lasts for a month.
The official end date for Ramadan is tomorrow on June 14.
Ramadan and Eid fall on different dates each year, as Islam uses the lunar calendar, which doesn’t line up perfectly with the Western calendar based on the solar cycle.
Eid, known in full as Eid ul Fitr, begins this year on June 15 and is when the first sight of the new moon is seen in the sky.
The celebration will see Muslims have their first daytime meal in over a month, and hold celebrations at their homes and in Mosques.
Eid is also a period of finery, when Muslims dress in their best clothes and give gifts to their friends and family.
Charity is also expected of celebrating Muslims, who will be encouraged to donate a set amount of money to help the less fortunate afford their own clothes and food.
Misalignment of the Gregorian and Islamic calendars means that Ramadan and Eid will be pushed back 11 days each year.
By 2020, we’ll see Ramadan fall in April, by 2023, March and by 2026 Ramadan will rake place in February
This will result in Ramadan falling on months with much shorter days, which means less time between the Suhoor and Iftar.
Muslims had particular trouble on longer days in 2016 when Ramadan coincided with the summer Solstice, resulting in the longest Ramadan for 33 years.
What is Eid ul Adha?
Ramadan is celebrated as one of the important five pillars of Islam, alongside, faith, prayer, charity and the pilgrimage to the Muslim holy city of Mecca.
The second most important festival in the islamic calendar is Eid ul Adha, which is regarded as the Greater Eid.
The festival falls from the 21st of August to the 25th, and celebrates the end of the annual pilgrimage to Mecca.
During this time Muslims will feast on an animal divided into three parts. One part is given to the poor, another to friends, and another shared with their family.
