Attached is a pre-built pack for the Australian NSW holidays.

These can be included into an existing schedule in an instance to be ran against SLAs.

its main feature is that it includes Easter Holidays up till 2039.

Goal is to save you time and hassle. minor config may be required.

I suggest ServiceNow to have these type of packs available for download for each region.

To implement, perform an XML import of the attached file. (test in a dev instance)
