Personally when people use 12am or 12pm I have always said to myself consider am = at morning and pm = past morning. So 12am to me = 12 midday. 12pm to me = midnight. Easier than am = ante meridiem (between midnight and midday) and pm = post meridiem(between midday and midnight.)
PM = Post meridiem: After noon. Using numbers from 1 to 12, followed by am or pm, the 12-hour clock system identifies all 24 hours of the day. For example, 5 am is early in the morning, and 5 pm is late in the afternoon; 1 am is one hour after midnight, while 11 pm is one hour before midnight.
19 kwi 2024 · Applying the same logic to PM, we can all agree that 1:00 AM is morning. Since the sun is unquestionably ahead of the meridian (ante meridian), one minute prior to this must be 12:59 AM. Thus, midnight is 12:00AM, and the early morning hours are 12:01–12:59 AM.

16 gru 2022 · Using the same thinking as for PM, we all know that 1:00AM is in the morning. One minute before this must be 12:59 and as the sun is definitely before the meridian (ante meridien) in this 12 hour period, it must be 12:59 AM.
