For a long time, I've wanted to integrate the Roman Breviary into a couple of projects (nothing public) but have never been able to find a suitable calendar, breviary or psalter implementation.
So I wrote one in python. It requires the `dateutil` package, but other than that its standard python. My principle use of this is going to be to create a JSON interface to get the current office, season, feast-day and reading from the 1962 Liturgical calendar. I am working on a "modern" liturgical calendar, its just not my priority right now.
