Based on astronomic calculations, Sept. 13 (Thursday) will be the first day of Ramadan while Dec. 19 (Wednesday) will be Arafat Day during Haj this year, according to Sheikh Abdullah ibn Munie, a member of the Council of Senior Islamic Scholars and the Umm Al-Qura Calendar Committee. Sheikh Munie, however, pointed out that the new crescent of Ramadan and Shawwal should be sighted by witnesses to determine the beginning and end of the fasting month, in accordance with Shariah regulations.
