ceiling fans in the winter are set to pull air up towards the ceiling thus moving the warm air down along the walls and causing it the then be circulated back up. this air flow moves cold air up to be heated. the reason you want the air moving up is so you do not feel the air flow on your body. in the summer you want to feel the air flow that is why your fan blows down.

michr has the right idea.
In summer, you want the fan blowing down on either medium or high so that you get concentrated air moving rapidly across your body to help cool you down.
But in winter, you don't want air blowing directly on you. You want the fan blowing up on low. That way, the low speed prevents a stung draft, and blowing up keeps from making the room right under the fan from feeling cool (because the concentration of air moving at the fan blades will be dis pursed by the ceiling).

Everybody agrees that warm air rises and cold air falls. However, it appears that people do not agree on the direction of fans in the summer and winter.
The following pages suggest running the fan so it blows up in the winter, and down in the summer:

The following page suggests that the answer is "subjective", and gives a more nuanced answer:

Personally, it seems that both directions will circulate the air, and neither will circulate it more efficiently in each season. So the most important factor to me is whether I want to feel a breeze below the fan or a less-noticeable breeze at the edges of the room. If I want to feel a breeze below the fan (like in the summer), I set the direction so that the fan blows down. During the winter, I generally have the fan blow up so that I am less likely to feel a chilly breeze.
If you are more concerned about air distribution than feeling a breeze, then you may want to to get really fancy and investigate putting in a duct from the bottom-used floor of your house to the top floor; it would have a reversible fan and in the winter it would suck the hot air from the ceiling of the top floor and redistribute it to the floor-level area of the bottom-used floor. In the summer it would do the opposite.

Anti-clockwise obviously! If going clockwise causes cold air then anti-clockwise produces warm air. Same as when driving forward uses petrol so going backwards fills the tank up again.

Give the 10 to JON; but consider that FANS are designed also to COOL people. not rooms. The very act of a fan; even in heated air will force it down; or draw it up; but will also Lower the temp of the heated air just in the agitation.
Another; and major issue to consider; no matter how many BTU's of heat you force into a dwelling; is how TIGHT and how well insulated that dwelling is.

Jon is wrong......If he would read the web sites correctly, summer down, winter up......in other words, summer clockwise, winter counter clockwise......
Oh....while I was writing this he pulled his answer.....
