@JeopardyTempest: The trouble with China, having a similar longitudinal spread as continental USA, Canada or Australia, is that it only has one time zone. The entire country operates on Beijing time and Beijing is in the east of China.

Midday is when the sun is at the highest point in the sky for any given day. Some would sat directly overhead.

The Earth is spheroidal in shape. As the Earth spins it presents a different line of longitude to the Sun so that with each passing moment a different line of longitude has the Sun shining directly on it. When this occurs it is midday for each line of longitude.
