12 noon is usually written as PM so 12 pm is noon.
“Noon” is the time of day when the morning ends and the afternoon begins. We use AM to show that it is morning and PM to show that it is afternoon and evening.
12 pm or 12 noon?
Technically “PM” starts after noon but most people use 12 pm to mean noon. If in doubt you can use “12 noon” or use a 24-hour clock where 12:00 equals midday(noon) and 00:00 equals midnight.
Is noon 30 AM or PM?
Noon 30 or 12:30 is “pm” because “pm” means “post meridian” and that means after midday.
