For those in the Northern Hemisphere (where I am) it’s the longest night of the year and the shortest day; the first day of Winter! Then sun has been moving away from us since the mid-summer, but now it will pause for 3 days, then start moving closer again in the Northern Hemisphere: the daylight will begin to lengthen again, and the nights grow shorter. Happy holidays!
