1. Start 09:00 = 540 minutes after midnight; end 17:30 = 1050 minutes after midnight.
2. Same-day gross = 1050 − 540 = 510 minutes.
3. Net = 510 − 30 = 480 minutes = 8 decimal hours.

Break time is deducted once from the gross clock interval. No automatic paid-break, rounding or overtime rule is inferred.

Use the break actually applicable to the work record; this tool does not determine labor-law entitlement.

How to use this calculator

Hours Worked Calculator works with time durations. Enter the times shown by the tool and read the elapsed result in the units displayed; overnight handling is stated beside the result when it applies.

Step-by-step

Step 1
Enter the start/base time.
Step 2
Enter the end time, duration or break requested by this calculator.
Step 3
Review the elapsed result and any day rollover shown.

Common questions

Can the calculation cross midnight?

Where the tool says overnight rollover is supported, an earlier end clock time is treated as the following day.

Are decimal hours available?

Work-duration tools show decimal hours where that representation is useful.

Are time zones included?

Ordinary clock-time inputs do not contain time-zone information. Use a Time Zone Calculator when zones matter.

Need a different calculation?

Use the calculator library to switch tasks when the question, unit or assumption changes.

Planning notes

Separate time on the clock from net worked time

Gross elapsed time and an entered unpaid break are kept separate so the result does not silently assume whether lunch or rest time is paid.

Example: 09:00 to 17:30 with a 30-minute unpaid break

Gross time is 8h30m. Subtract 30 minutes once to get 8h00m, or 8.0 decimal hours.

Useful for

Daily timesheet checks
Payroll-ready decimal-hour conversion
Shift record review

Limits and assumptions

Only the break you enter is deducted.
Paid-break and labor-law rules are not inferred.
For weekly overtime and multi-day records, use the richer payroll/time-card owners.
