Separate elapsed and actual work time
Elapsed time runs from start to finish. Actual work time subtracts lunch and other unpaid breaks.
When breaks are entered as total minutes, add all separate breaks first.
- Elapsed = finish - start
- Actual = elapsed - breaks
- Accumulated = daily actual × workdays
Example: 09:00 to 18:00
The elapsed time is nine hours. Subtracting a 60-minute break leaves eight actual hours, or 40 hours across five identical days.
For late arrivals or early departures, calculate each day separately rather than relying on an average.
Overnight shifts
When the finish is earlier than the start, the calculator treats it as next-day finish. A 22:00 to 06:00 shift is eight elapsed hours.
Multi-day duty and overlapping rotations require the official time record rather than a simple daily estimate.
Pay and legal limits require separate rules
This is a personal time-recording estimate and does not decide overtime, night, holiday pay, or break compliance.
Payroll also needs wage definitions, premiums, paid breaks, and workplace rules. Use official attendance records as the final source.
Overnight shifts and multiple breaks
A shift from 10 p.m. to 6 a.m. crosses midnight and has eight elapsed hours. Subtracting a 30-minute meal and another 20-minute break produces a recorded 7 hours 10 minutes.
Add multiple breaks in minutes. Whether waiting, training, or travel counts as work can depend on control and applicable rules; the calculator does not make that legal classification.
- Treat an earlier end time as the next day when appropriate
- Elapsed time - all breaks = recorded actual time
- Classify breaks, waiting, and travel separately
Record weekly and monthly totals accurately
Multiplying one standard day by the number of days misses lateness, early departure, overtime, and holiday work. For an irregular schedule, calculate each day first and total by week.
A monthly estimate based on four weeks differs from actual calendar workdays. Payroll review should follow the employer's pay period, contract, and workplace rules.
Why the result is not an overtime-pay decision
Recorded time alone does not determine overtime, night, or holiday premiums. Contracted hours, business size, worker status, flexible schedules, and holiday rules may change treatment.
Keep daily clock records, breaks, and approved overtime, then compare them with the payslip. For a material or repeated difference, use the employer contact or an official labor-advice channel for the specific case.
For schedule changes or partial employment months, total daily records rather than multiplying an average day. Keep who changed an attendance record and when so payroll uses the same version.
- Use the result as a personal time record
- Confirm the employer's minute-rounding method
- Check current law or professional advice for pay entitlement
