" Where there is no vision, the people perish: but he that keepeth the law, happy is he.
"
-- Proverbs 29:18, King James Bible (KJV)
Many modern religious holidays trace their origins back to ancient astronomical calendric feasts. So also the time around Christmas. The Winter Solstice in 2019 occurs on December 22 at 04:19 UTC (Coordinated Universal Time) which is 05:19 by Central European Time and still falls on December 21 rather than December 22 in many time zones in America.
