The Holidays can be setup as 'Special Event' holiday types. These holidays do not affect other schedules. For example a Type 1 holiday set to being a special event will not have any effect on any other time schedules. The schedules will not be overridden as they would be with other holiday types.

Note: The Special Event holiday type option check box will only display if NXT Mercury Powered or Mercury hardware is enabled on the license. This option is NOT supported on standard NXT or PXL controller types. When you check the option a bold message appears notifying you of this.
