Formula
total_seconds = (d×86,400 + h×3,600 + m×60 + s) ± (…); weekly pay = min(H,40)·rate + max(H−40,0)·rate×1.5
- • Convert both times fully to seconds, then add or subtract.
- • Normalize back to days/hours/minutes/seconds by successive division.
- • Time card: sum weekday hours; hours beyond 40 earn 1.5× overtime pay.
Pro tips
- • Borrowing is automatic: subtracting 2h50m from 5h30m correctly gives 2h40m.
- • Use decimal hours for payroll but d/h/m/s when tracking durations.
- • Overtime thresholds vary by jurisdiction — 40 h/week is the US federal standard.
