Why today is one of my favorite days of the year

Do you know what today is? Well, for those of us in the northern hemisphere, it's the winter solstice and the official first day of winter. Now I am not a fan of cold, so the start of winter isn't what makes my heart happy. Since this is shortest day of the year, it's all downhill from here. Slowly but surely the days start growing longer tomorrow. That is something worth celebrating in my book.
