Hours between times formula

For same-day times, subtract the start from the end. For overnight times, add 24 hours before subtracting.

\[\text{duration} = \text{end time} – \text{start time} – \text{breaks}\]

Example: 9:00 AM to 5:00 PM is 8 hours. A 30-minute break makes it 7 hours 30 minutes.

Overnight shift example

10:00 PM to 6:00 AM crosses midnight. The calculator treats 6:00 AM as the next day, so the result is 8 hours before breaks.

\[2\text{ hours to midnight} + 6\text{ hours after midnight} = 8\text{ hours}\]
