Is there any difference between the Task Calendar, Project Calendar and Resource Calendar other that

[ks2008]

Is there any difference between the Task Calendar, Project Calendar and
Resource Calendar other that where it is applied.

Meaning
*Resource Calendar: *Calendar Applied against the Resource.
*Task Calendar : *Calendar Applied against the Task.
*Project Calendar: * Calendar Applied against the entire project.

All three type of calendars are created using the same steps and the
scope of all three calendar are the same, that is to entire project.

Is my understanding is correct ?

Hi,

To add some detail to Trevor's reply.
Project Calendar is only used for scheduling tasks that do NOT have a
resoruce assigned NOR a task calendar connected to it. It is only the
default.

Adding a bit further to the other comments ... the Project calendar controls
tasks before resources are assigned to them and also defines the basic units
used for summary task durations, milestone placement on the timeline, lag
and lead times, etc. Once resources are assigned to tasks, the resource
calendar takes over control. Where multiple resources are on a task, the
resource calendars control each resources portion of the total task effort
and what one sees for the task is the aggregate effect of all of the
individual resource calendars. Task calendars are exception calendars
created for those circumstance where one needs to modify the behaviour one
would get leaving the project and or resource calendars in sole control.
