We all know after midnight, it's a new day. That's going by the clock or the calendar. But in our normally in conversations, it doesn't go that way, does it?
For most of us, a new day is after we have woken up from sleep. So, 12.15 am is still 'tonight' , though actually it is 'tomorrow'.
But for some of us who sleep a few hours after midnight or we have to make a reference to a time a few minutes past midnight, it's quite tricky.
I know a friend who missed a flight which he was supposed to board a few minutes past midnight. When boarding time is 12.15 am on Sunday, it's actually Saturday night! But he thought it's Sunday night 15 minutes past midnight.
So is 12.15 am, tonight or tomorrow morning?!
