Track monthly overtime hours and split them into overtime within the legal 8 hours, overtime over 8 hours, late-night hours and holiday work — entirely in your browser. Pick a name, year and month and the tool lays out one row per day with the date and weekday (weekends are shaded). Enter clock-in, clock-out and break (minutes) for each day; worked time is clock-out minus clock-in minus break, and the portion over your scheduled hours (selectable 7:00–8:00) up to the legal 8 hours counts as in-legal overtime, while anything over 8 hours counts as over-8h overtime. Hours overlapping the night window (22:00 to 05:00 next day) are counted as night, and any day you mark as a holiday counts entirely as holiday work. Overnight shifts (clock-out earlier than clock-in) are treated as the next day. Rounding is adjustable with a unit (5/10/15/30 minutes, or none) and direction (down, nearest, up), and the time display switches between h:mm and decimal hours, with totals per category at the bottom. "Fill weekdays 9:00–18:00" drafts a week quickly. Click "Print / Save PDF" to print at A4 actual size or save as PDF. Your name and clock times are never uploaded or stored — all calculation happens on your device — and only the scheduled hours, rounding unit, direction, display and accent color are remembered. This tool totals time only; it does not compute overtime pay or any monetary amounts.
