8.0 hours paid; repeat for five days and sum for weekly total near 40.0.
When to use Hours / Time Card Calculator
Rounding to quarter hours and subtracting unpaid lunch breaks is repetitive. A time card calculator totals decimal hours consistently.
Common use cases
- Verify paycheck hours against a paper punch card.
- Freelancers tracking billable time by day.
- Managers auditing overtime before approval.
Inputs and outputs
- 12-hour or 24-hour clock times

Frequently asked questions
- Overnight shifts?
- If end time is earlier than start, the tool should add 24 hours to end for next-day clock-out.
- Decimal hours vs hh:mm?
- Payroll often uses decimals (7.5 = 7:30); toggle display if offered.
- Overtime rules?
- This tool sums hours; legal overtime thresholds vary by jurisdiction and are not applied automatically.
