December 21, 2016 is the winter solstice and the the first day of winter. It is the shortest day and the longest night of the year and is believed to influence the date of Christmas. Celebrate with these memes.
For inhabitants of the Northern Hemisphere, the winter solstice process becomes most noticeable around December 1 when the sun appears to “move” south and get smaller. By the day of the actual winter solstice, the sun has reached its lowest point in the sky at -25.5°. Once it has reached this lowest point, an interesting thing happens: the sun appears to stop moving south for three days. After this, the sun moves 1° north, announcing the coming of spring. It will continue to move northward until the summer solstice when it reaches its highest point. (Imgur)
