On the basis of all the scientific information available, the moon will not be visible with the naked eye on Monday evening (8th). The first day of Ramadhan is expected to be Wednesday 10th July 2013.
The rules of the Umm al-Qura calendar system of Saudi Arabia allow for the start of the new Islamic month on the 29th night if:
1. The geocentric conjunction occurs before sunset.
2. The moon sets after the sun.
Both of these criteria will be met on Monday evening (8th) even though the moon cannot be seen with the naked eye. Saudi Arabia will announce the start of Ramadhan as Tuesday 9th July 2013.
Update (Once Ramadhan began):
With the Grace of Allah, Saudi did not begin the new Islamic month on the basis of a moon which set one minute after sunset in Makkah on Monday 8th July 2013. This is only one of the handful of occasions since the new Umm al-Qura formula was established ( 2002 / 1423) that a fixed civil date has been overridden.
The majority of the Muslim Ummah began Ramadhan on Wednesday 10th July 2013.
