The fasting hours during the Holy month of Ramadan are set to begin from 25 May 2017 and are expected to end by 25 June 2017 based on moon sighting reports.

Ramadan ends when the first crescent of the new moon is sighted again on 25 June 2017, Sunday. Eid Al Fitr is the Islamic holiday that marks the end of Ramadan.

In the UAE, work days are usually shortened by two hours during Ramadan.

Ramadan consists of fasting from dawn to sunset. Muslims all over the world fast during the days of this month and make special prayers at night.  The month of Ramadan traditionally begins with a new moon sighting, marking the start of the ninth month in the Islamic calendar. They abstain from food, drink, and certain other activities during daylight hours in Ramadan.

Although Ramadan is always on the same day of the Islamic calendar, the date on the Gregorian calendar varies from year to year, since the Gregorian calendar is a solar calendar and the Islamic calendar is a lunar calendar. This difference means Ramadan moves in the Gregorian calendar approximately 11 days every year.

The date of Ramadan may also vary from country to country depending on whether the moon has been sighted or not. The duration of daily fast depends on the amount of hours between sunrise and sunset, which is affected by which season Ramadan falls on.

During summer months, those observing the month of Ramadan have to fast longer hours due to the longer days, which vary in length depending on the country they live in.
