Assalamu alaikum/greetings, a bit of an interesting moon bits for this month, as I’ve not been able to find any positive moon sighting reports for the start of Rabi-al-Thani for Saturday evening, 03/05/2011, for the USA, (or anywhere else for that matter). However, as 03/05/2011 was the 30th day of Rabi-al-awwal, the start of Rabi-al-thani will automatically be 03/06/2011. Crescentwatch explains the lack of positive sighting as a result of overcast/cloudy skies.
But Alhamdulillah, no worry as 30 days is as long as the month can go, so 03/06/2011 it is, as far as the start of Rabi-al-Thani goes for the USA. The same for those following the Ummul Qura calendar. The next time to attempt hilal sighting from the next month of Jumada-al-Oola should be Inshallah 04/03/2011.
