---Returns the month, day, and index of the event selection used only for CalendarContext functions. The selection state referenced by this function is used only by other CalendarContext functions; other calendar event functions use the selection state set by CalendarOpenEvent, CalendarNewEvent, CalendarNewGuildEvent, or CalendarNewGuildAnnouncement (if they use a selection state at all). Used in the default UI to implement the calendar's context menu (on right-click).
