Liturgical Calendar API exposes Roman Catholic liturgical calendar computed according to the norms set forth by the liturgical reform after the II Vatican Council. Several Sanctorale calendars are available and others can be added easily.

Expected audience are developers of websites and other Internet applications needing access to calendar information.
