The Time Card Calculator totals hours worked across a pay period from multiple clock-in/out entries. This Time Card Calculator handles date and time calculations precisely, accounting for variable month lengths, leap years, and calendar rules automatically.

The formula behind this calculator: Sums each shift's duration, subtracting unpaid breaks, across all days in the period. As a practical example: Five 8-hour shifts with a 30-minute unpaid lunch each total 37.5 hours for the week. All results are calculated instantly in your browser — no data is stored or transmitted.
