The initially recorded usage of the term was in 1143 when the author of Novgorod First Chronicle spoke to the winter solstice as "Korochun.” It was celebrated by pagan Slavic on December 21, which was the lengthiest evening of the year and the darkness of the winter solstice.
On this night, Hors, embodying the old sun, becomes smaller as the days progress. It finally dies on December 22, which is the winter solstice. It is believed to be conquered by the dark and evil influences of the Black God. On December 23, Hors is brought back to life and becomes the new sun, Koleda.
Have you ever wondered why people have actually started celebrating the Winter Solstice? This was started by Sol Invictus, who is a Syrian god. He believes that this gives a chance to the sun to regenerate. Some say that this has already started since the Neolithic period-the last part of the Stone Age began about 10,200 BC.
The Pagans also started to celebrate this before, and they called it Yule. There are various festivals that are done all over the world that are made specifically to align with the Winter Solstice. Some people believe that this is very spiritual because they believe that this gives a chance for the sun to regenerate.
