>>The exact  opposite.  The sun begins to rise, but never quite makes it
over the  horizon.  Noon is its high point, when it comes closest to
the horizon,  so that is when we must count a notional sunrise and sunset
and change the  date, just as we do in summer at midnight.<<  [--RZS]

I can imagine how one would know when the sun has reached its highest  point 
in the sky for the day when the sun is actually in the sky, but how on  earth 
would one know when the sun had come closest to the horizon on a day in  
winter when the sun never actually peeked over the horizon and was never visible  
in the sky?!
