"Let's meet Saturday night at 2 o' clock" is "incorrect" and could never happen (calendar wise)
Midnight is the start of a new day. So anything after that is the next day (again, calendar wise)
But most people knows what is means and sees 2 o' clock after midnight as the same day
For most people it does not mean Sunday morning at 2 o' clock. Especially party-people, night owls etc. ;) At least in daily speech. "See you tonight at 2 o' clock!" etc.
This makes it difficult to have a user calendar with date/time on a website
Should I put a notice: "Remember, a calendar day starts/ends at 00:00 / 12 AM"? That could confuse people
Or do people already know this when dealing with a calendar?
How do you get about it?
