The Celts called it "Imbolc" (the 'b' is silent, so some other possible puns went South), the time when we moved out of winter and into spring. Our co-ordinates on the elliptical orbit is left as an exercise to the reader.

  1. Gronhog, or mid-winter day has nothing to do with the elipticty, of earth's orbit or its position therein, but with the tilt of the earth to the plane of its orbit and being the halfway point (in time, not distance) between the point of maximum tilt of the earth's north pole in the direction away from the sun and the tiem of zero tilt from the earth-sun line.
