Shifts, breaks, overtime, and payroll decimals — the whole timesheet workflow in plain typed expressions.
HR time math has two constant traps: breaks that have to come off every shift, and the hours-to-decimal conversion payroll requires (7h 45m is 7.75, never 7.45). TCalc handles both — durations are real values and decimal output is one tap away.
The HR layout below has one-tap keys for standard shifts and breaks, so a full week of clock-ins takes seconds to total.
One shift: clock-out minus clock-in minus unpaid lunch.
A whole week totalled and shown as payroll-ready decimal.
Overtime: actual week minus the standard 40 hours.
Different break length? Just change the number.
Clock-out minus clock-in minus unpaid breaks: 17:30 − 09:00 − 30m = 8h. TCalc evaluates the whole expression at once, per day or per week.
Minutes divided by 60: 39h 15m = 39.25 hours. In TCalc you switch the output format to hours and any total displays as decimal — no conversion tables.
Subtract the standard week from the actual total: 42h 30m − 40h = 2h 30m of overtime. With PRO you can save your standard week as a one-tap custom button.
