12pm 有人说是中午12点 有人说是晚上12 到底tm谁对？
我怎么就认为是 晚上12点呢？
搜索后发现很多人问这个 最后还tm采纳12pm 是中午12点位最佳答案 我感觉很不爽
到底12am 和 12pm 这种用法标准码？
12pm指中午十二点。
因为PM为拉丁语post meridiem的缩写，表示午后，适用于十二小时制，指每天的12:00:00～23:59:59时段。
与PM相对的是AM（拉丁语ante meridiem缩写），意为“中午之前”，表示上午，指每天的00:00:00～11:59:59时段。
扩展资料
十二小时制整点时间表示
1、午夜12:00，也就是夜间00:00，12:00 ante meridiem（12 o'clock AM）/12:00 midnight （12:00 AM）。
2、凌晨1:00~上午11:00，表示为1~11 ante meridiem（1~11 AM）。
3、中午/下午12:00~下午/晚上11:00，表示为12、1、2、3……11 post meridiem/PM。

12PM 是中午
记得我刚来美国的时候，有门课程12PM开始。当时我问教授怎么晚上那么晚了还上课。他笑着说12PM是中午。
其实，中国人中分不清楚12AM和12PM的大有人在。我相信很多人把12AM当成是中午，12PM当成晚上。就168肯定就有很多人分不清楚。

所以我在规则里面，尽量不用12，都用11：59啥的。
Are noon and midnight 12 a.m. or 12 p.m.?
This is a tricky question. The answer is that the terms 12 a.m. and 12 p.m. are wrong and should not be used.
To illustrate this, consider that "a.m" and "p.m." are abbreviations for "ante meridiem" and "post meridiem." They mean "before noon" and "after noon," respectively. Noon is neither before or after noon; it is simply noon. Therefore, neither the "a.m." nor "p.m." designation is correct. On the other hand, midnight is both 12 hours before noon and 12 hours after noon. Therefore, either 12 a.m. or 12 p.m. could work as a designation for midnight, but both would be ambiguous as to the date intended.
When a specific date is important, and when we can use a 24-hour clock, we prefer to designate that moment not as 1200 midnight, but rather as 0000 if we are referring to the beginning of a given day (or date), or 2400 if we are designating the end of a given day (or date).
To be certain of avoiding ambiguity (while still using a 12-hour clock), specify an event as beginning at 1201 a.m. or ending at 1159 p.m., for example; this method is used by the railroads and airlines for schedules, and is often found on legal papers such as contracts and insurance policies.
If one is referring not to a specific date, but rather to several days, or days in general, use the terms noon and midnight instead of 12 a.m. and 12 p.m. For example, a bank might be open on Saturdays from 8 a.m. to noon. Or a grocery store might be open daily until midnight. The terms "12 noon" and "12 midnight" are also correct, though redundant.

在中文，上午12点指的是中午12点。
不过在英文里，12AM是凌晨0点。
出国三年了，国外都是这样的。
我们不说多的。把自己的windows XP的右下角显示时间的东西调成12小时制前面加上AM PM(或上午，下午)显示。然后在等到中午12点，你就知道了。本回答被提问者采纳

12pm 是中午12点
其实楼主以为 12pm是晚上12点很正常 因为am是上午 pm是下午 所以既然5pm是下午5点 那么很自然 12pm应该是晚上12点吧 我一开始也是这样认为的 但是这恰恰是英语中的特例 12pm是中午12点 12am才是晚上12点 所以这只能死死地像背单词一样背下来 楼主打破砂锅问到底值得鼓励 Good Luck！
