This marks the day that the official formation of the United Arab Emirates took place on December 2, 1971.

During the build-up, and on the day itself, it is not uncommon to see Emiratis displaying their patriotism by wearing scarfs or carrying flags in the colours of the UAE. Many also have their cars decorated in the colours of the flag or with pictures of the sheikhs.
The day is a public holiday and takes place during a period when the weather in the UAE is at its best.
