#### TYPICAL OBJECTS OF TYPE Joint Calendar

This type represents a union or intersection of several Calendar objects.

In a loose sense, a union of calendars is a new calendar of which the holiday set equals the union of the holiday sets of each member calendar.

More precisely, a date is non-business in a union of calendars if and only if it is non-business in at least one of the member calendars.

Similarly, an intersection of calendars may be loosely characterized as being a new calendar of which the holiday set equals the intersection of the holiday sets of each member calendar.

More precisely, a date is non-business in an intersection of calendars if and only if it is non-business in all of the member calendars.

Certain

**objects can be trivial objects and as such are automatically generated from text that satisfies certain formatting rules.**
