What the calendar may show

- Inspections
- Calibration
- Contractor visits
- Shutdowns

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.
