This support article will outline the process of adding an exception to schedule holiday hours in CTM.
Click on the Numbers menu at the top left of CTM.
Click on Schedules.
Click Edit beside the type of hours you would like to change, i.e business hours.
Scroll down to the very bottom of the page by the Exceptions panel. Click on the Add Exceptions button.
*An exception is a set of specific date ranges that can be excluded from the normal operating times above. Using this feature will allow you to exclude full days from the business hours schedule.
An Add New Exceptions window should appear. Fill out the fields: Name, Description, and Date Range. You will want to use the dates of the holiday in the Date Range field, and you do need to select both a start date and an end date (even if it’s the same day). After you have completed the fields, click the Add Exception button.
Click the Save Changes button at the bottom of the screen.
