How to Calculate Hours Between Times

To find hours between two times: convert both to 24-hour format (if needed), subtract start from end. If the result is negative (crossing midnight), add 24 hours.

Example: 9:30 AM to 5:45 PM = 17:45 − 09:30 = 8 hours 15 minutes = 8.25 hours. For 10:00 PM to 6:30 AM (overnight): (24:00 − 22:00) + 6:30 = 2:00 + 6:30 = 8.5 hours.

Converting Minutes to Decimal Hours

Payroll and billing systems often use decimal hours instead of hours:minutes. To convert: decimal hours = hours + (minutes / 60).

8 hours 30 minutes = 8 + 30/60 = 8.5 hours. 7 hours 45 minutes = 7 + 45/60 = 7.75 hours. 6 hours 20 minutes = 6 + 20/60 = 6.333 hours.

To reverse: take the decimal portion × 60 to get minutes. 8.75 hours → 0.75 × 60 = 45 minutes → 8 hours 45 minutes.

Weekly Hours and Overtime

In the US, the Fair Labor Standards Act (FLSA) requires overtime pay (1.5× regular rate) for hours worked over 40 in a workweek. Some states have additional rules — California, for example, requires daily overtime for hours over 8 in a day.

Track your weekly hours carefully if you are hourly. Use this calculator to sum shifts across a week, ensuring you capture all hours including short shifts that may not seem significant individually.
