# OCRotation- Global

The OCRotation script include provides methods to build a data structure that is used to display a calendar.

The code builds up the GlideAJAXSchedulePage object which stores a list of span items. You can use this type for the Gwt \(legacy\) calendar. See the [OCRotationV2 - Global](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/api-reference/server-api-reference/c_OCRotationV2.md) script include for other calender types. This is part of On-Call Scheduling.
