Eid ul Fitr day...
Eid-al-Fitr (Eid al-Fitr, Eid ul-Fitr) is the first day of. the Islamic month of Shawwal. It marks the end of Ramadan, which is a month of fasting and prayer. Many Muslims attend communal prayers, listen to a khutba (sermon) and give zakat al-fitr (charity in the form of food) during Eid al-Fitr.
Muslims across the world will be greeting each other by saying "Eid Mubarak" in June, when the month-long fast of Ramadan comes to a close.
Because the timing of Eid al-Fitr is based on the Islamic lunar calendar, it can be difficult to predict when the festival will take place.
