The Catholic Liturgical Calendar is an iPhone application that provides users with information about Holy Days, Feasts, and the start and end dates of the Catholic seasons. Developed by Joseph Stalin Alucious Selvaraj, this free app is categorized under Education & Reference.

The liturgical calendar in the Catholic Church is a significant tool for Catholics to keep track of important dates and seasons. The app allows users to easily find the Holy Days and Feasts for any year, making it convenient for Catholics to plan and prepare for these special occasions. Additionally, the app dynamically calculates the start and end dates of seasons such as Advent, Christmas, Lent, and The Triduum (Good Friday, Holy Saturday, and Easter Sunday) based on the first day of Advent.

Currently available only in English, the Catholic Liturgical Calendar app is user-friendly and provides accurate information. The developer plans to add support for multiple languages in the future. Users are encouraged to share their feedback and suggestions by leaving comments and ratings.
