The calculator finds the next service milestone and converts remaining hours to calendar days.

Service intervals based on operating hours rather than calendar time. More accurate for machines with variable usage.

Use an hour meter on the machine, SCADA system, or manual logbook.

Hours-based for critical equipment with variable usage. Calendar-based for simpler time-based tasks.

Set daily hours to 24. The calendar interval equals service hours / 24.

Track each interval separately: oil change every 500h, filter every 1000h, overhaul every 8000h.
