Source: Webster's dictionarySince the beginning of AH 1423 (16 March 2002), the rule has been clarified a little by requiring the geocentric conjunction of the sun and moon to occur before sunset, in addition to requiring moonset to occur after sunset at Mecca. Source: Internet
The new calculation requires that conjunction occur before sunset in Mecca, Saudi Arabia and that moonset on the following day must take place after sunset. Source: Internet
The time between moonrise and moonset would be over 29 hours. Source: Internet
This ensures that the moon has moved past the sun by sunset, even though the sky may still be too bright immediately before moonset to actually see the crescent. Source: Internet
