A few people have written to me recently to say that Universalis does not correspond to their local calendar: specifically, that they are celebrating the Epiphany on Sunday 4 January and Universalis is showing it on Tuesday 6 January.
This email is a reminder that Universalis does have some local calendars built in to it. If you are seeing feasts such as the Epiphany on the wrong date, this is probably because you are using the General Calendar instead of your local one. Follow the "Local Calendars" link at the top of any Universalis page, and you will see a list of calendars that you can choose from.
(If you are using the downloaded Universalis rather than the web site, follow the links at the bottom of http://www.universalis.com/n-download.htm for instructions on how to set your local calendar).
Note for Canadian users: I am aware that the Canadian bishops have now moved the Epiphany, the Ascension, and Corpus Christi to Sunday, and the next update to the database and to the downloaded versions will include this change.
