Re: Ramadhan, Eid and Moon-sighting
Regardless of one can see the moon before sunset or not, you are right that even when moonset is before sunset moon is present in the sky. Actually, moon is present in the sky everyday at one time or another. It is obvious, because there is 'moonrise' everyday and 'moonset' everyday ... and as long as moonset has not happened there would be moon present in the sky.
Anyhow … ‘Chand-raat’ … or ‘night of the moon’ is the first night of the month when there was moon in the sky when night started. Night starts just after sunset and not before sunset. That means moon should be sighted in the sky after sunset and not before sunset.
For instance: Every month (once every 29 days or 30 days) moonset passes sunset. That is, one day moonset was before sunset and next day it was after sunset. When this transition happens new month starts, not before.
