The International Liturgical Calendar or International Rite is a proposed unified and perpetual liturgical calendar for Christian faiths (Orthodox, Catholic, Protestant) that is compatible with ISO 8601 by being based upon the International Calendar, i.e. the Gregorian months and an accompanying week calendar.
