Why its clockwise always...

Everything happens for a reason ,isn't it? ,then why clock hands are always designed to move clockwise.Even if its gonna be designed to move anti clock wise,we ll get the same result but y clock wise.The reason is simple.The first ever clock was designed by Egyptians and it is called Sundial.
The working of Sundial is based on the rotation of the earth around the sun.As the earth turns on its axis, the sun appears to move across our sky. The shadows cast by the sun move in a clockwise (hence the definition of clockwise) direction for objects in the northern hemisphere.
If the same clock is used in southern hemisphere(Eg.Australia),the shadows cast by the sun move in a anti clockwise direction.Since the first clock was designed in Egypt which lies in northern hemisphere,every clock designed later followed the same clockwise rule.Simple as that;)
