Does it actually fall on this friday night, meaning December 24th?
Actually I understand that its not on the same date each year but that it comes out on a different date, as it follows the Hebrew Calendar in what we must watch for, despite it following the xtian holiday of the 25th.
By the way I was once in a funny community when this date fell. The town was running around covering each and covering every food item in their homes with anything plastic or aluminum to save it from being affected by the Ruach Tamei which descends on the world at that time.
WHen I started this meshugius as well, my husband just turned to them and asked one question. All the food in the grocery stores which is now uncovered, in the chain stores and yiddishe stores alike, are you telling me that tommorrow you are not going to buy food that was not covered and protected?
They had no answer.
