A comprehensive calendar app to view dates of significance in the Catholic Christian community such as Holy Days of Obligation, Feast Days, Days of Observance and Seasons in the Liturgical year.

The dates are colour coded in the main page and there is a function to filter the dates according to the users' preference.

There is also an Appointment page where users can add and manage their appointments. The Appointments are also colour coded in the main page.

This calendar is based upon the last revision of the General Roman Calendar made in 1969 and used mainly among member countries of the International Commission on English in the Liturgy (ICEL). Nevertheless, adorations are allowed on different theological orientations. Hence, feast days and holy days of obligation may differ from one country or one community to another.

While the information on this calendar is true and complete to the best of our knowledge, changes in circumstances after the time of publication may impact on the accuracy of the information. This calendar is provided for general informational only.
