text: Days are counted as complete turns relative to the sun, so you are always facing the sun at noon. If you did the turns relative to the room you're in, you're modeling sidereal days. A sidereal day is one turn of the earth relative to the stars, 23 hours, 56 minutes, four seconds. If you go you at midnight six months apart, you will see that relative to the stars, you are facing in opposite directions.
