If you live on a planet that circles a sun, your time is governed by the patters of light and darkness, summer and winter, warmth and cold. And, of course, life and death. Once our forebears learned to farm, they planted and harvested at the equinoxes, but it was the solstices that caught their attention. The extremes. They watched their days shrink from the bright abundance of high summer to the bleak, dark cold of winter, and they invented rituals to make sure the light would come back again: to bring the new day, the new year, the rebirth of life.
