👨🏻🏫 -> Earlier people used to use a sundial to calculate the time of the day.
The Clock (analog) we have now is made in the clockwise direction to mimic the shadow movement of the sun on a sundial.
🧑🏻🦱 -> But the sun's shadow moves in the counterclockwise direction in the southern hemisphere. Then why the northern hemisphere?
👨🏻🏫 -> Excellent question.
- As the earth rotates on a 21.2-degree axis, in the Southern hemisphere the sun's shadow moves in the anti-clockwise direction, but the reverse in the northern hemisphere.
- Now why the Northern hemisphere is the cause of Population density.
- The population density is more in the northern hemisphere than in the southern hemisphere. Therefore, the Clockwise direction.
Sundial shadow movement in the anti-clockwise direction in the Southern Hemisphere:
Sundial shadow movement in the clockwise direction in the Northern Hemisphere:
Therefore, a clock rotates clockwise to match the shadow of the sun's movement in the densely populated northern hemisphere.
