I like to reckon the Hebrew date by the sighting of the new moon in Yerushalayim, however, and I rely on a notification from the New Moon Society which I receive from the ministry of Michael Rood. This Hebrew month, I received the following report which you may see along with the page for the ninth Biblical month at:
That report stated:
"Yesterday (November 23, 2014) the new moon was not sighted in Israel due to heavy cloud cover. That means that by default, this evening, November 24th, at sunset is the first day of the 9th Biblical month. Because atmospheric conditions like this cannot be predicted, the AACBH (Astronomically and Agriculturally Corrected Biblical Hebrew) Calendar this month is a day off. You will need to subtract one from each Biblical date this month. Hanukkah will begin on December 18th at sunset!"
All that to say, that by the sighting of the new moon in Yerushalayim; Hanukkah should officially begin at sunset on December 18, 2014 and not at sunset on December 17 as I indicated in my blog post. Please don’t let the confusion over dates keep you from celebrating Hanukkah this year, however. The Rabbinical reckoning of December 16 at sunset for the beginning of Hanukkah is as good any because you will be joining the great majority of Jewish people in their celebration of this wonderful eight day remembrance of Yahveh’s miraculous interventions to save His People.
