Not only is this a celebration of being given the privilege of completing such an auspicious month, but it is also a day to thank Allah (SWT) for gifting the strength and determination to enable the month to be completed. This self-restraint is something that can then be followed as an influential example of how one should imminently practice.
The day of Eid-ul-Fitr is determined by the official sighting of the full moon in Saudi Arabia which marks the first day of the following month (Shawwal). However, Eid dates differ around the world, though they are usually within one or two days of each other.
Muslims all over the world unite and adjoin in the congregational Eid prayer after the disbursing of their Zakat or Fitrana. The remainder of the day is spent rejoicing amongst family, friends and loved ones; celebrating by way of giving gifts, enjoying meals together, visiting the mosque, and so forth.
Many people also often wear their best clothes on this day to mark the occasion.
