You can only delete a calendar if it's in the New state.
A calendar is in the New state after it's been saved and before it's been associated with a master position.
The calendar becomes Inactive once a master position is associated with a calendar.
It becomes Active once the associated master position is assigned to an employee.
Select Human Resources Configuration from the HR or Administration menu. The window opens displaying the General tab.
Click on the Calendar tab. Note: Be sure that the accounting cycle displayed beside the Logout button is the accounting cycle that contains the calendar you want to delete. If this is not the correct accounting cycle, select a different one.
Check the box for the New calendar you want to delete, and click the Delete button. You'll be asked to confirm your action.
Click Yes.
