Eid Al Fitr is the Islamic holiday that marks the end of Ramadan .
During Ramadan , work days are usually shortened by two hours in the UAE.
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 .
The duration of the daily fast depends on the number of hours between sunrise and sunset, which is affected by which season in which Ramadan falls. The date of Ramadan may also vary from country to country depending on whether the moon has been sighted or not.
