Comma separated, or a single number applied to every day.

An hours total, not a payroll calculation. Overtime is applied weekly only, with no daily threshold and no deductions.
Total paid time for the week
37.5 hours
5 days · 150 min unpaid break
Overtime here is applied to the weekly total, which is the US federal rule under the Fair Labor Standards Act — anything over 40 hours in a workweek, however it falls across days. Several US states and many other countries also apply a DAILY threshold, commonly after 8 hours, and this does not model that. It is also not a payroll calculation: no tax, no deductions, no jurisdiction-specific rules. Treat it as an hours total that you or your payroll provider then apply the actual rules to.
How the Time Card Calculator works
Enter a week of start and end times with unpaid breaks for the total paid hours, split into regular and overtime, and gross pay if you supply an hourly rate. Overtime is applied to the weekly total, which is the US federal rule — the page is explicit that daily thresholds exist elsewhere and are not modelled.

Frequently asked questions
How do I calculate a weekly timesheet?
Total the paid time for each day — elapsed time less unpaid break — then add the days. Convert to decimal hours before applying an hourly rate.
When does overtime start?
Under US federal law, after 40 hours in a workweek regardless of how they fall across days. Several US states add a daily threshold, commonly after 8 hours in a day, and many countries have their own rules. This applies the weekly threshold only.
Is this a payroll calculator?
No. It totals hours and applies an overtime multiplier. There is no tax, no deductions and no jurisdiction-specific rule set. Use the hours figure as an input to payroll rather than as a payroll answer.
How should I record a shift that crosses midnight?
Enter it as it happened — 22:00 to 06:00. It is counted as eight hours. Which day the hours belong to for overtime purposes is a payroll policy question rather than an arithmetic one.
