When clocks were first made, they were modeled on the existing timepiece of the sun and the sundial.

In the Northern hemisphere the sun appears to track across the sky in a clockwise direction. When facing towards the position of the midday sun (south in the northern hemisphere): starting from the east, the sun appears to rotate or follow an arc up and north and then south and down across the sky during the day.

In the southern hemishere the apparent arc and rotation is anticlockwise when facing towards the position of the midday sun (north).

Generators rotate in a clockwise direction because of the right-hand rule of electromagnetism. When current flows through the wire in the generator's magnetic field, a force is generated that causes the wire to move. This movement results in the rotation of the generator in a clockwise direction.

Because it's designed that way. It's completely aribitrary. They could have made them spin counterclockwise, however the engine would have to be designed differently, as well as the shape of the propellers.

Look on the side of the fan's body to see if you can see a reversing switch. The switch is there to let the home owner reverse the direction of the fan blades. For home ceiling fans, the air should be moving down in the summer time. In the winter time when the home heating unit is being used, the air should be drawn up to the ceiling. This causes a flow pattern that circulates up through the fan to the ceiling, across the ceiling and down the walls to the floor where it gets drawn back up to the ceiling. This rotational pattern draws the warm air from the ceiling and redistributes it to the floor where you can sense the warmth.
