Ola Ilori posted that Biblical calendar is off by a month.
That is totally false.
If you check Biblical Astronomy for March April of this year, it is reported that the Barley was in Aviv in Jerusalem on March 12th of this year. The barley in Aviv or ripening determines the date of the beginning of the calendar.
Nehemiah Gordon stated that the new Biblical year began on March 17th 2010.
The seventh month begins on October 10th according to Nehemiah Gordon. Furthermore, because the new moon will not be visible until after dark of the 10th, Rosh Hashanah will be observed officially as September 11th.
It was true that the established Hebrew calendar for 2009 was off by one month, however it has no bearing on 2010 since the Biblical agricultural calendar is determined by the Barley being in Aviv or “Ripe”. Not so this year.
