both 0000 to 1200 is AM, and 1200 to 0000 is PM.
Use the 24-hour clock to prevent mis-understanding, as Europe and the US Military: 1200 is Noon, 0000 or 2400 is midnight. Thanks - I agree but that doesn't solve the computer time clock problem. The slot to the right of 12:00 on my system always has either AM or PM. Most of North America uses a 12 hour clock so the problem is not solved by switching to a 24 hour clock. Greenwich doesn't have an answer - "12:00 AM and 12:00 PM have no meaning." http://wwp.greenwichmeantime.com/info/noon.htm
1200
I t is impossible to answer the question since there is no time such as 1200 am. It is either 1200 noon or 1200 midnight and, for obvious reasons, they will give different answers.
I am assuming that you mean "how do you change the time from a 24 hour clock to a twelve hour clock." Just subtract 1200 hours from any time over 1200H. 0000H is midnight. 0100H is 1:00 am etc. up to noon. 1200H is Noon. 1300H is 1:00 pm (ie 1300 - 1200 = 100 = 1:00 pm). 1600H would be 4:00 pm (1600 - 1200 = 400 = 4:00 pm). 2200H is 10:00 pm (2200 - 1200 = 1000 = 10:00 pm).
No 1200 hours is midday. Midnight is 0000 hours (zero hundred hours)
1200 hrs. There is no such corresponding time for midnight. Reason midnight could be either '0000' or '2400'. , but which day does it refer. So midnight on the 24 hour clock does not occur. You have either 2359 hrs (on a given day) or 0001 hrs. ( the next day), that is 2 minutes later. .
both 0000 to 1200 is AM, and 1200 to 0000 is PM.
It's a 24 hour clock, so no AM or PM. The first two digits are hours, second two are minutes. The day starts at midnight, which is 2400 of yesterday and 0000 of today. Everything after noon (or 12:59 PM to be precise), you just add 1200 to the time. From midnight to 1 AM the hour is 00 (i.e. you subtract 1200 from civilian time.)
12am in military time is 0000 or 00:00 ("zero hundred" or simply "midnight") 12pm is 1200 (twelve-hundred. Or midday)
AM (Ante Meridiem, Latin for Before Midday) is between 0000 and 1200, and PM (Post Meridiem, Latin for After Midday) is between 1200 and 0000.
Usually, 2400 hours (some say 0000 hours).
1230 PM in military time is 1230 hours in the 24-hour clock format.
Are we talking of 12 noon or 12 midnight. 'pm' means 'post meridian' (Latin) for 'afternoon'. If it is 12 noon it is neither before nor after noon , it is 12 NOON. A similarl argument holds for 12 midnight. 'am' are the Latin initials for 'ante meridian ' ; before noon'. In military time ; 12 noon is 1200 hrs. 12 midnight is NEVER used because of confusion over the date/day . The time of '0000' and '2400' is the same instant. So to avoid confusion the earliest/latest times used are 0001/2359 hrs respectively.

9pm is 2100 hours Navy / Military time, which is based on a 24 hour clock system. 12am is 0000 hours, 1am is 0100, 12pm is 1200, 6pm is 1800 hours, etc.
1200 pm is noon. Midnight is typically referred to as 12:00 am.
