11.5 decimal hours · 12 h shift span − 30 min unpaid break

Example inputs are filled in. Change them and calculate your own result.

How the calculator works

The calculator converts each time to minutes after midnight. If the finish is earlier than the start in automatic mode, it adds 24 hours. You can also choose the end day explicitly. Paid time equals the shift span minus unpaid break minutes.

Paid minutes = end minutes + next-day minutes − start minutes − unpaid breaks

Divide paid minutes by 60 for decimal hours. A result of 7 hours 45 minutes is 7.75 hours, not 7.45.

Dates and clock changes

This is wall-clock arithmetic for one shift. It does not apply a time zone, daylight-saving adjustment, payroll rounding or a legal break rule. Equal start and end times mean zero hours in automatic mode; choose Next day for a full 24-hour span. For a clock-change night, verify the actual elapsed time separately.

Values stay in this browser page. The calculator does not submit your times or save them to an account.
