There is only one day when the tree calendar is not mentioned at all.
It is 22 December, a special day, known as Nameless Day, which holds a special place in folklore and legend. On this day, when the 'king of the waning half-year' had disappeared into darkness and the 'king of the rising half-year' had yet to be born, it was customary to fast to placate the queen in the dark layer.
