Eid al-Fitr is often called the “Festival of Breaking the Fast.” The practice of dawn-to-sunset fasting during the holy month of Ramadan ("Sawm") is one of the five pillars of Islam. Muslims believe that it was during the month of Ramadan that the text of the Qur'an was revealed to the Prophet Muhammad.
Muslims celebrate Eid Al-Fitr with prayers called "Salat Al Eid" in Arabic. There is no audible call to prayer for the Eid prayers. Muslims will gather in mosques or open spaces and offer two units of prayer – called "Rakat". The prayers are followed by a sermon, in which the imam asks for forgiveness, mercy, and peace for every being across the world.
It's a tradition to wear new clothes and on the way to the mosque, eat something sweet such as a date, and recite a small prayer called a takbeer.
Other key elements of the Eid celebrations are giving money to the poor (known as 'Zakat al-Fitr', the amount to be given depends on the possessions someone has), sending Eid greetings and feasting with families.
For many Muslims, Eid al-Fitr is a festival to show gratitude to Allah for the help and strength he gave them throughout the month of Ramadan to help them practice self-control.
