Resource Calendar
A schedule that lists, for each resource, the specific dates and time blocks (shifts) when that resource is available for assignment.
Key Points
- Captures availability for specific people, equipment, or facilities by day and shift.
- Enables realistic task scheduling, resource allocation, and resource leveling.
- Shows exceptions such as holidays, leave, training, maintenance, or overtime limits.
- Differs from the project calendar, which sets general work times for the whole project.
Example
On a construction project, the tower crane is available Monday to Wednesday from 7:00 AM to 3:00 PM, and the certified operator is off next Friday. The project manager reviews the resource calendar and schedules all lift activities within the crane and operator overlap to avoid delays.
