The Muslim feast of Eid al-Fitr, marking the end of the holy month of Ramadan, began Thursday for Palestinians, according to the Grand Mufti of Jerusalem.There was slight confusion over the timing of the new moon, but the Muslim Iftaa department in Palestine called on people to follow its directives, explaining that in case the new moon is seen tonight people will be required to fast an additional day to complete at least 29 days of fasting. Eid al-Fitr falls immediately after Ramadan, the holy month when observant Muslims fast from dawn to dusk. Ramadan can last either 29 or 30 days, depending on when the first moon of the next lunar month is sighted, and the dates often differ from country to country.Over 2.5 million worshipers prayed atop the Al-Aqsa Mosque during the entire month of Ramadan, the Al-Aqsa Foundation stated on Thursday.Palestinian news agency Ma'an quoted the foundation as saying the majority of worshipers appeared for Friday prayers and during Laylat al-Qadr - celebrated on odd nights often towards the end of Ramadan, depending on the Islamic sect.
