Paste in a week's worth of daily shift times and breaks to total your weekly hours worked and see how much qualifies as overtime.

How It Works

How Time Card Calculator Works

Each line you enter follows the format day,start time,end time,break minutes (for example, Mon,09:00,17:30,30). For every valid row, the calculator finds that day's worked duration by subtracting start from end (adding 24 hours if the shift wraps past midnight) and subtracting the break minutes, the same method used by the standalone Time Calculator.

All the daily durations are added together into a weekly total. Anything above your chosen overtime threshold (40 hours by default) is reported separately as overtime, so you can see both regular and overtime hours at a glance.

Worked Example

See It In Action

Two entries — Mon, 09:00-17:30, 30-min break (8h 0m) and Tue, 09:00-18:00, 45-min break (8h 15m) — total 16 hours 15 minutes so far, all regular time since the 40-hour weekly overtime threshold hasn't been reached yet.

Real-World Use Cases

Who Uses Time Card Calculator and Why

Totaling a full week's worked hours from a set of daily clock-in and clock-out times pasted in at once.
Checking a pay period for overtime when shift lengths differ from day to day.
Verifying a paycheck against manually logged daily hours before payday.
Comparing planned versus actual hours across a work week with irregular shifts.

Common Mistakes

Mistakes to Avoid

Not matching the expected comma-separated format (day, start time, end time, break minutes) exactly, which can cause a line to be misread.
Leaving the overtime threshold at the default 40 hours when your job or jurisdiction uses a different weekly cutoff.
Pasting shifts out of order and assuming the weekly total is still correct — the total math is unaffected by order, but it makes double-checking individual days harder.

Pro Tips

Tips for Best Results

This is the tool to reach for over the hours calculator whenever your schedule has a different shift length on different days, since it accepts one line per day rather than assuming a repeating shift.
Paste one line per shift and keep the day labels consistent so the weekly breakdown is easy to scan.

Troubleshooting

Fixing Common Problems

A day's hours look wrong in the breakdown. — Check that line's format matches day, start time, end time, break minutes exactly, separated by commas, as shown in the placeholder example.

The overtime split doesn't match my paycheck. — Confirm the overtime threshold field matches the actual weekly hour cutoff used by your employer or jurisdiction — it's adjustable and defaults to 40 hours.

Glossary

Terms Explained

Overtime threshold: The total weekly hours above which additional worked time counts as overtime, adjustable in this tool to match your specific job.

Regular hours: Hours worked up to the overtime threshold, calculated separately from any hours above it.

FAQ

Frequently Asked Questions

What format should each row follow?

Each line needs four comma-separated values: a day label, start time (24-hour HH:MM), end time (24-hour HH:MM), and break minutes — for example, Wed,08:30,16:45,30.

Does this handle overnight shifts?

Yes — if a row's end time is numerically earlier than its start time, the calculator automatically treats it as crossing midnight and adds a full day's worth of minutes before subtracting the break.

Can I change the overtime threshold?

Yes — the "Overtime after" field defaults to 40 hours per week but can be set to match your employer's or jurisdiction's specific overtime rule.

What happens if one row has an invalid time?

Rows with times that can't be parsed are skipped from the total rather than causing an error, so double-check the daily breakdown shown in the results against your entered rows.
