How this time card calculator works
Add one row for each work block, project block, or day. Each row has a label, start time, end time, and break minutes. The calculator totals net time across all rows and shows decimal hours for simple checking.
If an end time is earlier than the start time, the row is treated as ending on the next day and labelled as overnight. Break minutes are subtracted from the row total. Incomplete or invalid rows stay visible with a specific error and do not contribute to the total. Minutes are summed exactly as entered; this page applies no rounding increment or overtime threshold. Rows are totalled independently; the calculator does not detect or remove overlapping time entries.
When a simple time card total helps
A time card calculator is useful for personal time tracking, checking work blocks, project logs, weekly planning, and quickly adding several clock-in and clock-out rows.
This page does not apply pay rates, overtime rules, tax rules, HR policies, or payroll rules. For a single shift, use the work hours calculator. For one elapsed time span, use the time duration calculator. For a fixed day-by-day week layout, use the weekly timesheet calculator.

Time card calculator FAQ
How is this different from the work hours calculator?
The work hours calculator focuses on one shift. This time card calculator totals multiple clock-in and clock-out rows with breaks.
Does it support overnight rows?
Yes. If the end time is earlier than the start time, the row is treated as ending on the next day and is labelled as overnight.
What happens to incomplete rows and decimal hours?
A row with a missing or invalid time is excluded from the total and shows a specific error. Valid minutes are also divided by 60 for the decimal-hours view; no rounding increment or overtime rule is applied.
Is this a payroll or tax calculator?
No. It is for personal checking, planning, and simple time totals. It does not apply payroll, overtime, tax, HR, or legal rules.
