Can I determine the 14th of an Islamic month from the full moon time shown in Moon phases Tables?
It is not true that the 14th of an Islamic month falls on a full moon day. Full Moon can occur on 13th or 14th or 15th of the month, because the full moon occurs at one specific moment Universal Time (that can be in the day or night) and at every moment, there are two Gregorian dates in the world (parts of the world on either side of the International Dateline have different days at every moment) and those two dates correspond to three different dates in Islamic calendar depending upon the location on the globe. Now, the sighting of the moon determines the beginning of the month not the moon birth. Sighting of the moon occurs on at least two different days on the entire globe, sometimes even three different days.
