Liturgical Calendar API provides structured access to the Roman Catholic liturgical calendar, returning daily liturgical season, calendar celebration (feast day, solemnity, memorial, or feria), liturgical color, and any special observances for any given date. The API supports the traditional Latin Mass calendar as well as the modern Ordinary Form calendar established by the Second Vatican Council, enabling Catholic parishes, seminaries, religious communities, and Catholic app developers to build liturgically-aware applications that keep track of the Church's annual cycle of feasts and seasons.
