Since noon is neither before nor after noon, and midnight could be considered the end of one day or the start of the next, neither label fits. However, it's a very common interpretation that 12:00AM means midnight (00:00 in 24-hour notation) and 12:00PM means noon (12:00 in 24-hour notation).

Similarly one may ask, why is 12am at night?

Re: 12 am = midnight or noon? Midnight is 12:00 pm. It is also 00:00 am. This is because it represents both the beginning and the ending of a set of numbers that runs from 00:00 to 12:00.

Also Know, how can I remember 12 AM and PM?

If midnight were 12 PM, then the minute before 1 AM would be 12:59 PM, which wouldn't make sense. The words come from Latin, but you can remember PM with an English mnemonic as "post-midday" -- anything after noon is post-midday, including 12:00:01 and 12:59 (one minute before 1 PM).

Why is 12pm noon and 12am midnight?

To avoid confusion, the correct way to express 12 o'clock is 12 noon or 12 midnight. At 12 noon, the Sun is at its highest point in the sky and directly over the meridian. It is therefore neither 'ante' (am) nor 'post' (pm).

Is it 12 am tomorrow or today?

Originally Answered: Is 12:00 AM yesterday, today, or tomorrow? In our system, tonight's midnight is the first moment of tomorrow. But as for the rest of us – there's no official answer and the military use a system in which midnight is 0 hours. In that system, tonight's midnight is the first moment of tomorrow.
