Is lunchtime 12 am or 12pm?
Midday and midnight conventions There are no standards established for the meaning of 12am and 12pm. It is often said that 12am Monday is midnight on Monday morning and 12pm is midday.

Is 12 pm noon yes or no?
12 noon can be neither 12 am (in English before noon) nor 12 pm (after noon). It is simply noon. Since we do not notate time backwards, 12 midnight is not 12 am, since it would then require 1 am to become 11 am and so on.
Why is 12 called noon?

Noon is considered 12:00:00 PM and 12:00:00 on the 24-hour time clock. The easiest way to rationalize this is that 12:00, 12:01, 12:02 are the first minutes of the day and consecutive so they are all AM.
