Is 12 AM noon or midnight?

I think people might get confused with offers that will end at 12 am or 12 pm. It's better to make it clear that it will end at 12 noon or 12 midnight. So is 12 am noon or midnight?

    12 AM is midnight. 12 PM is noon. It used to confuse me too, until I started just thinking 1 minute ahead. 12:01 PM, of course is after noon, therefore PM.

    I agree, think like Drake, think one minute ahead.

    That doesnt make sense though.....I think

    If 11am is the morning 12 in the middle of the day should be called am too not pm. PM should begin from (1 in the afternoon) 1PM so people dont get confused.

    Once again if 11 at night is 11pm, 12 midnight should be called 12PM not 12am....the next hour which is 1 oclock should start the AM cycle.

    Have no idea if that makes sense and I'm not reading it again but I know what I mean:p

    Who can we chat with about changing this?

    12:00 starts the next cycle, so 11:59 PM ends the PM cycle. As it rolls over to 12 it becomes AM. I'm not sure who you'd have to chat with about changing it. Perhaps whoever decided that daylight savings time made sense

    Thanks, guys. One more thing... If you said the offer will end on Feb 10 midnight, does that mean one minute before 12:01 am of Feb 10 or one minute before 12:01 am of Feb 11?

    There are 24 hours in a day. Each 12:00 = half. Half the day = am, the other half = pm.

    AM = ante meridiem or before noon
    PM = post meridiem or after noon

    This one always confused me as well. Changes from person to person.

    To me, Feb 10 at midnight equals one minute after Feb 9 11:59pm.

    One minute after 11:59 on the 10th would roll over to the next day, making it the 11th. Midnight on the 10th, to me, means one minute after midnight on the 9th. But then again, I've been known to show up for midnight mass on the wrong day because of that.

    Each period consists of 12 hours numbered: 12 (acting as zero), 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, and 11.

    The 12-hour clock was developed over time from the mid-second millennium BC to the 16th century AD.

    So are pointless posts, apparently.

    Am I the only one who was taught this in elementary school?

    Of course, it is very confusing if the offer doesn't say which time zone they're talking about.

    Look 12 AM in midnight should be called AM because 12 AM would mean that 12th PM has been finished and 1st AM has been started. 12:00 AM will act as the beginning of 1st AM. When 60 minutes pass then you get 1 hour. Although you will see 12:01, 12:02 and think hei we are still in the 12's so it should have remained in PM etc. But the fact is 12:01 means 12th PM hour has been finished and 1st minute of 1st AM hour has passed already.

    I hope you got the point here. So no change is necessary. It was correct all the time.

    I hope I have not been too confusing.

    There's an easier way to deal with this problem. If your offer ends at midnight ... and you let it run until 12.10, no one is going to sue you!
