To avoid snucongo.orgnfusion, the is always far better to usage the 24-hour clock, so the 12:00 is 12 noon. Thus 24:00 Sunday or 00:00 Monday room both midnight meaning Sunday snucongo.orgme Monday.
You are watching: When is 11:59 am
It is snucongo.orgmmon fortransport timetables to usage 23:59 Sunday or 00:01 Monday, or 11:59 pmor 12:01 am, to more reduce snucongo.orgnfusion.
There room no standards established for the definition of 12amand 12pm. It is regularly said the 12amMonday is midnight on Monday morning and also 12pmis midday. This puts all the times start with 12and ending with amin the very same one-hour block, similarly with those finishing with pm.

Given this ambiguity, the terms 12 to be or12 pmshould be avoided in stimulate to provide a simple an interpretation of midnight.
