Twelve Holy Days is the holy period, from December 26 to January 6, in the Esoteric Christian interpretation of the Christmas season. The night between the 24th and 25th of December is considered to be the most "Holy Night", when the Sun (the "Light of the World") commences its journey from the south to the north. On the night when he commences his northward journey the zodiacal sign virgo, the celestial virgin (the "Queen of Heaven"), stands upon the eastern horizon at midnight (thus he is "born of a virgin" without other intermediary, hence, "immaculately conceived.") .
