If you have booked an absence which has passed but was not taken, you may remove it from your calendar by going to the “Holidays/Absences” link at the top of the page, navigating to the absence on your absence calendar and clicking on it.
The absence details page that displays shows the current details of the booked absence. To remove it, click on the “Cancel Absence” button at the bottom of the page. The dialog box that is shown allows you to enter a reason why you want this historical absence removed from your record. Clicking on the “Cancel Absence” button on this form generates a new absence request and routes it to an administrator. Once approved, the request will remove the absence from your record. You will be notified by email when the request has been approved.
