Ceiling fans: direction they should turn for hot weather?

I noticed that my Ceiling Fans have a switch to change which way they turn (clockwise and counter….) which way is it that would be the most benefital in hot summer weather?
Because there’s a lot of conflicting answers I want to clarify with the correct answer:
Ceiling fans are normally used as a cooling device in warm months by pushing air down from above, thereby creating a wind chill effect. In winter months, a ceiling fan can act as a heat transferrer by reversing the direction of the blades. By doing so, the fan pulls air up, thereby pushing the warmer air that stratifies near the ceiling down along the walls; as long as the fan is set at a low speed, this will not create a wind chill. A fan on reverse has the leading edge of the fan blades being the downward edge; in most cases this rotation is clockwise when the operator is standing below and looking upwards at the fan.

Depends on which way the blades are mounted, but the air should be pushed upwards, as opposed to blowing hot air downwards.

Ceiling fans are great energy savers and are great for cooling your room in the summer and circulating warm air in the winter. In the summer, you want the fan blades to push the air down onto your skin, essentially creating a cool breeze. In the winter, reverse the direction of your fan’s blades so they are pulling cold air upwards and pushing the warm air down around the edges of the room.

Summer time you want the air blowing straight down to cool the room. Winter time you want it blowing up so it brings the warm air around the room.
