The Catholic calendar starts on the first day of Advent, which is 4 Sundays before Christmas. The other seasons are calculated based on this date.
The Liturgical Calendar application will help you to find the Holy Days, Feast for any year on the go! The catholic feasts like Advent start date, Tridumm, Lent are calculated dynamically for each year.
The Liturgical Calendar application is in English language. Support for multiple languages will be added and published soon.
