Where does a new day begin?

Answer 1

A new day starts at midnight, 00:00 Hours on the 24 hour clock. There is some confusion as to whether this is 12 A.M. or 12 P.M. on the 12 hour clock, although 12 A.M. is most often used as a synonym for midnight.

Think of it this way:

12:01 in the afternoon is 12:01pm, therefore it follows that 12:00 should be pm, though technically it is not "post meridian" until a fraction of a second after 12:00 (but it's not "ante meridian" either). This is the way computers display it (and "they" MUST be right! :) )
