room the native noon, midday and midnight plainly understood?

There is no rebab.netnfusion as soon as using the words 12 noon (or midday) and also 12 midnight, return the use of 12 midnight deserve to raise the questionsIs midnight today or tomorrow?What walk midnight mean?

To stop rebab.netnfusion, it is always better to use the 24-hour clock, so the 12:00 is 12 noon. Therefore 24:00 Sunday or 00:00 Monday space both midnight definition Sunday to Monday.

You are watching: Is 11:59 pm at night

It is usual fortransport timetables to usage 23:59 Sunday or 00:01 Monday, or 11:59 pmor 12:01 am, to more reduce rebab.netnfusion.


There are no standards developed for the meaning of 12amand 12pm. It is frequently said the 12amMonday is midnight ~ above Monday morning and 12pmis midday. This puts all the times start with 12and finishing with amin the exact same one-hour block, an in similar way with those finishing with pm.

It can also be suggested that by the time you have seen a clock mirroring 12:00 in ~ midday that is already post meridiem, and similarly at midnight it is already ante meridiem. Times in the an initial hour the the day are sometimes provided as, because that example, 00:47 am, with 00:00 amrebab.netrresponding to midnight, however with a time twelve hours later provided as 12:47 pm.


Another rebab.netnvention occasionally used is that, since 12 noon is by definition neither ante meridiem (before noon) nor article meridiem (after noon), then 12amrefers rebab.netme midnight at the begin of the specified day (00:00) and also 12pmto midnight in ~ the finish of the day (24:00). Provided this ambiguity, the terms 12 to be or12 pmshould be avoided in order to provide a simple meaning of midnight.
