Use this when the user wants a time card calculator or hours worked calculator: totaling clock-in/clock-out times for a day, week, or biweekly period, with lunch breaks, multiple in and out punches per day, overnight shifts, 12-hour or 24-hour (military) time, punch rounding (nearest 5/6/15 minutes or the 7-minute rule), overtime and double time per workweek (US federal 40 h, California daily rules, or custom), and gross pay from an hourly rate. Pass times as the user wrote them; times without am/pm ("9 to 5") are resolved and the reading is returned in assumptions for the user to confirm. Returns per-day hours in H:MM and decimal, regular/overtime/double-time split, totals, exact gross pay, warnings (overlapping punches, missing clock-out, shifts over 16 h), and CSV and printable PDF timesheet links. Does not compute taxes or take-home pay, give legal advice about breaks or overtime, track time live, or set reminders. Do not use for simple unit conversions without clock times.
