I’m no domain expert but I’m guessing flights are scheduled at 12:01am because people are bad at time. For instance some people would think 12am is the last minute of the previous day instead of the first minute of the next day. 12:01 removes the potential ambiguity.
- nothrabannosir 7y agoNitpick but since we’re talking about time: AM means “ante meridiem”, as in “before”. Not anti as in “against” :)
- OJFord 7y agoYou've just completed GP's point perfectly though - 12 hours after noon (post meridian) is midnight too.
- Mountain_Skies 7y ago12 "post meridian" is 12 hours after noon. 12pm. Which is midnight. But you don't use 12pm to mean midnight. Why not? Midnight doesn't actually belong to a day at all. Our current conventions of 12am and 12pm seem to be mostly products of digital time keeping.
