UPDATE: The new moon was not sighted from Israel on the evening of the 10th. We did see the tiny sliver hanging above the Gulf of Mexico here in Florida. However, Israel is ground zero, and their observation stands. The first day of the 7th month, and the Feast of Trumpets, will fall on sunset Tuesday 11 September by default.
The 7th month new moon is expected Monday night! Get out your shofars, and be looking up!
