explain Midday and noon & etc

What is difference of "Midday" and "noon"?

Noon is the time exactly halfway through the day, written 12:00 in the 24-hour clock and 12:00 noon (or PM) in the 12-hour clock. Midday is also used as a synonym for noon, although this may also be a more general term to mean around noon, or very early afternoon.
