Calculation path
Both clock readings are converted to minutes after midnight. The calculator adds one day only when you select next day, then subtracts the entered break.
Calculation path
Elapsed minutes = end clock - start clock, plus 24 hours only for next-day end. Duration after break = elapsed minutes - break minutes.
What you receive
What you receive
