Hadith of the Prophet Mohammad (PBUH) which says, "You
start fasting when you see [the moon] and stop it when you sight [the next
moon] and when it is hidden by clouds, complete [30 days of] fasting."
Muslim should follow the teaching of The Holy Qur'an and Hadith of Prophet(SAW). Thats why even in this time of sophisticated astrological calculation, mulsims rely on sighting of moon than rely on the calculations. The calculations can be right or wrong according to the methods/person.
