Subtracted from the total

Enter a start time and an end time to get the exact duration in hours and minutes, decimal hours and total minutes. Add an unpaid break to subtract it. If the end time is earlier than the start, the calculator assumes the next day, so night shifts work too. You can also add or subtract a duration from a clock time.

Worked examples

9 to 5 with a 30-minute lunch: 9:00 AM to 5:00 PM is 8 h 00 m on the clock; minus 30 minutes gives 7 h 30 m, or 7.5 decimal hours.
Overnight: 11:00 PM to 7:30 AM is 8 h 30 m. Because 7:30 AM is earlier than 11:00 PM, the calculator counts across midnight.
Add time: 2:45 PM plus 3 h 20 m is 6:05 PM. 8:00 AM minus 45 minutes is 7:15 AM.

How it is calculated

Duration = end − start, in minutes; if end is earlier than start, add 24 hours. Subtract the break. Decimal hours = minutes ÷ 60, rounded to two decimals. Adding a duration to a clock time wraps at midnight and reports the day change.
