Elapsed time across days
Durations spanning midnight or multiple days need date and time together — timestamps, essentially. This calculator subtracts full timestamps and re-expresses the result as days, hours, and minutes, which is how flight times and shift logs are computed.
Time zones are the catch
Two timestamps in different zones can't be subtracted directly — a 6-hour flight leaving at 3 pm and landing at 5 pm crossed four zones. Convert both ends to one zone (UTC is the neutral choice) before doing duration math.
