Start and end in minutes after midnight
total minutes = hours × 60 + minutes
8 × 60 + 45; 17 × 60 + 15 = 525 and 1,035
End − start − break
duration = end − start − break
1,035 − 525 − 0 = 510
As hours and minutes
hours = minutes ÷ 60 (whole), the rest stays minutes
510 min = 8h 30m
How it works
Duration = end − start − break (adds 24 hours when the end is past midnight)
