勤務時間計算機とは?
無料のオンライン勤務時間計算機。労働時間数とタイムカードの合計時間を計算。
Tracking work hours accurately is essential for payroll, freelance billing, and personal productivity management. Hours Calculator (Time Card) provides a complete time-tracking solution with support for multiple days, break deductions, overnight shifts, overtime calculation, and CSV export.
Add entries for each day using the date picker and clock-in/clock-out time selectors. The calculator automatically computes the total hours worked for each day, subtracting any break minutes you specify. Overnight shifts (clocking out past midnight) are handled automatically — if the clock-out time is earlier than clock-in, the calculator assumes the shift crossed midnight.
The overtime section lets you set an hourly rate and an overtime threshold (default 40 hours per week). Hours worked beyond the threshold are calculated at 1.5x your base rate. The total regular pay, overtime pay, and combined pay are displayed in a clear breakdown with daily summaries.
The CSV export button downloads all your time card data as a CSV file suitable for payroll processing, spreadsheet import, or record keeping. Each row includes the date, clock-in, clock-out, break minutes, regular hours, overtime hours, and pay for that day.
