Which direction should a ceiling fan turn?

Perry in Cochrane, Alberta wants to know which way a ceiling fan should turn. Don't try to remember clockwise or counter-clockwise -- I always get that mixed up. Simply remember that in the summertime, moving air of any temperature feels cooler if it is blowing directly on our skin. The evaporation of moisture cools us. So in the summer we want to feel the air current so we want the fan pushing the air down. In the winter air has to be quite warm to feel good if it blows right on us, so in the winter you want the air to blow upward and bring the warm ceiling air down around the edges of the room where it will not feel like a cold air current.
