Liturgical and Proper calendars

In Paul Turner's Blog by Paul Turner

Q:  Please describe the difference between the Liturgical and Proper calendars available from USCCB site.

A:  The proper calendar indicates the dates that are unique to the United States Conference of Catholic Bishops. These need not appear in other episcopal conferences in the same way.

The liturgical calendar incorporates the proper calendar into the general calendar so that it is easy to follow in the US.
