Add & Subtract Hours, Minutes, Seconds
Add or subtract time durations. Calculate total hours and minutes from multiple time entries — perfect for timesheets.
Adding Time Durations
Adding time requires carrying over minutes past 60 into hours. 8:30 + 7:45 = 16 hours 15 minutes (30+45=75 minutes = 1 hour 15 minutes, carry the 1). This calculator handles the conversion automatically and shows the result in hours:minutes, decimal hours, and total minutes.
Time Calculations for Timesheets
For payroll, time is often needed in decimal hours — 8 hours 30 minutes = 8.50 hours, not 8.30. Common conversions: 15 min = 0.25 hours, 30 min = 0.50, 45 min = 0.75. Multiply decimal hours by your hourly rate for gross pay calculation.
