The weekend in the the U.A.E. for most government and public services as well as businesses runs from Friday to Saturday; for many, Thursday may be a half day (although most often work all day Saturdays). In nearly every city, commercial activity will be muted on Friday mornings, but after the noon services at the mosques most businesses open and Friday evenings can be crowded.

The major exception is during the fasting month of Ramadan, when the rhythm of life changes drastically. Restaurants (outside tourist hotels) stay closed during the daylight hours, and while most offices and shops open in the morning from 8 AM to 2 PM or so, they usually close in the afternoon while people wait (or sleep) out the last hours of the fast. After sundown, people gather to break their fast with a meal known as iftar, often held in outdoor tents (not uncommonly air-conditioned in the UAE!), which traditionally starts with dates and a sweet drink. Some offices reopen after 8 PM or so and stay open well after midnight, as many people stay up late until the morning hours. Just before sunrise, a meal called sohoor is eaten, and then the cycle repeats again.
