Romcal
A Program to Generate the
General Roman Calendar
of the Catholic Church

R omcal is a C Language software package that generates the General Roman Calendar of the Catholic Church. The program uses the revised liturgical calendar for the Western Church as approved by Paul VI in Mysterii Paschalis dated 14 February 1969, and implemented in the United States in 1972, although any Gregorian year may be given to the program. The data files that support the program have been updated to include celebrations added to the calendar through 1995. While the liturgical year begins with the First Sunday of Advent, this program computes based on a calendar year. Originally written in 1993 as a mental exercise on my part, it has undergone four major revisions and now supports several output formats. Romcal is implemented, maintained, and packaged on a Unix computer system, although it should compile okay on a PC.

Romcal Version 6 (1/31/2003) adds support for the iCalendar format (.ics). This format can be used to import calendar information into other schedule and calendar software such as Microsoft Outlook.

A new version (7/19/2003) of fixed.dat, which provides the program with the dates, ranks, and colors of the fixed celebrations of the calendar, is now available. This version incorporates the celebrations that have recently been added to the calendar. The example output files below, for 2003 and 2004, have been updated with the new celebrations.

As with past versions, Romcal is offered in the hopes that it will be useful, and I don't expect anything in return for its use other than courtesy of not selling it, plagiarizing it, or blaming the author if anything goes wrong. See the disclaimer and license for more information.
