Merry "X"mas
Q's crumbs regarding Xmas and Christmas seem to lead to THIS week. By using a 15 minute offset:
-
December 25, 2017 lines up with January 1, 2019
-
December 21, 2017 lines up with December 31, 2018
Note that December 21st (2018) was the Winter Solstice (dark to light) and beginning of the government shutdown.
I think it is VERY much worth noting that December 5th (D5) lines up with January 4th, 2019.
Also, notice the "X" pattern on the clock as in "X"mas.
