Here comes the sun,
Here comes the sun
And I say it’s all right. – George Harrison
Though people have affixed all sorts of mythology to the holiday, the real reason it exists is the event which occurred last night at 23:03 UTC: the winter solstice, when the apparent course of the sun reaches its southernmost point. Last night was the longest of the year, and for the next six months the days will increase in length while the sun’s apparent course moves northward. For modern people, wrapped in our technological cocoons and insulated from Nature, it hardly makes any difference; but for our ancestors, dependent upon the return of the spring for their crops to grow, the “rebirth” of the sun was a cause for joy and celebration. It meant they could be sure that, no matter how cold the rest of the winter to come might be, that it would eventually end; the snow would melt, the plants would blossom and the crops upon which civilization depended could be cultivated. There’s still a lesson there for us: no matter how bleak things may appear, and no matter how oppressive the weight of tribulation, there is yet hope; the sun always returns, and spring always comes, even if we must endure dreadful storms before it does. And if that isn’t a reason to celebrate, I can’t think of a better one.
