"post meridiem" ("after noon").
Meridian is the Latin word for Noon. Ante Meridian (AM) means before noon, and Post Meridian (PM) means after noon.
PM means at night or at noon
This is not really a question. AM stands for ante meridiem which means before noon. PM stands for post meridiem which means after noon.
one means morning and the other means after noon
AM stands for "ante meridiem" and refers to the time from midnight to noon, while PM stands for "post meridiem" and refers to the time from noon to midnight. AM starts at 12:00 AM (midnight) and ends at 11:59 AM (noon), while PM starts at 12:00 PM (noon) and ends at 11:59 PM (midnight).
Neither. The correct way to identify 12:00 is to say 12:00 noon or 12:00 midnight.am stands for ante meridiem which means before noon and pm stands for post meridiem which means after noon. Since noon itself is neither before noon or after it, the use of am and pm is not appropriate. The same argument can be applied to midnight.
“AM” stands for the Latin phrase Ante Meridiem —which means “before noon”—and “PM” stands for Post Meridiem : “after noon.”
Noon is PM, midnight is AM.
Post Meridiem "AM" means ante meridiem, or before noon. "PM" means post meridiem, or after noon. The "M" is the meridiem, or middle. In our day, that is noon, or 12:00 PM ... Meridiem being of Latin origin is often spelled incorrectly as Meridian.
1200 PM would be noon, or 12:00 in the afternoon.
AM stands for ante meridiem, which means "before noon" in Latin. PM stands for post meridiem, which means "afternoon" in Latin. These terms are used to differentiate between times in the morning (AM) and times in the afternoon and evening (PM).
Midnight to Noon is AM. Noon to midnight is PM.
