I'm sure there will  be others commenting on the dates that H Schutta (2 Nov 2014) "6 Days of Darkness and News blackout" shared. http://www.fivedoves.com/letters/nov2014/hschutta112.htm

In the next lunar month of Bul/Cheshvan these December dates will be around the start of Chanukah, the 22nd being near the new moon.
