Winter Solstice arrives precisely on December 22nd at 05:30 GMT, or 11:30 CDT on the 21st. At this moment, the northern hemisphere will be at its darkest. The axis of the planet is pointing directly off into space, but it is also starting its wobble back towards the sun that brings all life to this humble planet. We celebrate it by turning off all electric light and enjoying a few moments with quiet and candlelight – just the music of the spheres to contemplate. This is our holiday for the season.
