Weekly punch ledger
Calculate weekly work time from clock-in and clock-out punches. Subtract one optional lunch interval per day, handle overnight shifts, and see exact hours and minutes plus decimal hours.
Punches stay in this browser page. This app calculates entered time; it does not determine payroll, wages, or legal overtime.
Enter both Clock in and Clock out for each worked day. Lunch is optional, but Lunch out and Lunch in must be entered together.
Split the weekly total at a time threshold for planning. This does not determine legal overtime.
The app converts each punch to an exact minute position, subtracts the lunch interval you enter, and adds valid worked days into one weekly total. It does not apply payroll or employment-law rules.
worked minutes = adjusted Clock out − Clock in − entered lunch minutesweekly minutes = sum of valid worked daysdecimal hours = weekly minutes ÷ 60Enter both Lunch out and Lunch in, or leave both blank. A lunch interval must sit entirely inside that day's work span. The calculator subtracts the interval you enter; it does not decide whether that time is legally compensable.
If Clock out is earlier than Clock in, the app treats Clock out as occurring on the next day. Internally that means moving the end time forward by 1,440 minutes before calculating the span.
Hours and minutes remain the exact time result. Decimal hours are a second representation: 7h 30m is 7.50 hours, not 7.30 hours.
The optional threshold splits entered time into “up to” and “above” the threshold. It does not determine overtime eligibility, overtime rates, or whether a meal period should be paid.
Punches stay in page memory. This version does not save time cards to browser work storage or send punch values to a Mycelgrid calculation API. Copy, CSV, and print are explicit local outputs you control.
For U.S. work-time context, see the U.S. Department of Labor hours-worked guidance and overtime overview. Rules depend on applicable law and facts; this calculator only performs entered-time arithmetic.
