"Between the woods and frozen lake, the darkest evening of the year." - Robert Frost
December 21st is the winter solstice, making it the darkest day of the year. Not dark in a brooding, tonal way, but physically dark as it is the day of the year with the shortest day and longest night. Celebrating the solstice dates back thousands of years, and civilizations across the globe followed different traditions and rituals. Many of these pagan rituals made their way into modern Christmas traditions, most notably the Christmas Tree. Being the darkest day of the year, the solstice the transition to longer days and shorter nights, eventually evening out on the spring equinox and peaking at the summer solstice.
