Catholic Calendar 3.00 shows the Regular Catholic Calendar and the USA Catholic Calendar, which are built on the standard guidelines of the official Roman Church. The current day of the month is shown in your system tray icon, with the day's feast displayed in its tooltip. The icon color indicates the liturgical rank of each celebration, and a simply click on it will bring up an overall view of the past and upcoming holy days between 1583-4900 AD, listed in a color-coded table. It provides you with detailed comments about each event, saints biographies, patronage, names meaning. Print and search functions are included as well.
