The moon does not disappear from the firmament save for the twinkling of an eye; even though there were a full thread (of light) surrounding it in the east and in the west, the eye has not the power to see the moon until eight large hours (have elapsed). (The large hours) are two hours for each (large) hour, either at the beginning of the Molad (conjunction) of the moon or at the end of the Molad of the moon.
The number of the days of the lunar year is 354 days, a third of a day, and 876 minims. || All the hours of a lunar month are 708 hours and 40 minutes; all the hours of a lunar year are 8504 hours.
