Christ was born on September 11th,
in the warm season,
when flocks were still tended to OUTDOORS at night.

That is why the Cabal attacks Humanity repeatedly on that September date, so we mourn instead of Celebrate, on the correct day.

Luke 2:8-11 King James Version
"8 And there were in the same country shepherds abiding in the field, keeping watch over their flock by night.
9 And, lo, the angel of the Lord came upon them, and the glory of the Lord shone round about them: and they were sore afraid.
10 And the angel said unto them, Fear not: for, behold, I bring you good tidings of great joy, which shall be to all people.
11 For unto you is born this day in the city of David a Saviour, which is Christ the Lord."
