What this term means in maintenance

A maintenance calendar is a time-based view of scheduled preventive, inspection, calibration, shutdown, contract, and corrective work.

What the calendar may show

A calendar may display:

  • Due work
  • Scheduled work
  • PM generation
  • Inspections
  • Calibration
  • Contractor visits
  • Shutdowns
  • Maintenance windows
  • Expiry reminders

Practical example

A supervisor reviews next month's PM tasks, contractor visits, calibration dates, and planned production stops in one calendar.

Calendar versus schedule

The calendar provides time visibility.

The committed schedule includes assigned resources and execution expectations.

Useful filters

Users may filter by site, team, asset, work type, priority, or status.

Common mistake

Showing thousands of unsorted work orders on one calendar makes the view unusable.

How this term differs

Maintenance Calendar is a time-based view of due and scheduled work rather than a resource commitment. It is related to Maintenance Scheduling, Maintenance Planner, and Maintenance Schedule Compliance, but these terms describe different records, measures, roles, strategies, or decisions and should not be used interchangeably.
