The scholars of the four schools of Islamic Law agreed that the basis for determining the beginning of Ramadan is as follows: The crescent is visually observed after the sunset of the twenty-ninth (29th) day of Sha^ban. If the crescent is sighted, then the following day will be the first day of Ramadan. However, if the crescent is not sighted, then the next day will be the thirtieth (30th) of Sha^ban and the day after will be the beginning of Ramadan.
