I confess I do not understand how the liturgical calendar "works", single feasts, double, double first class; it confuses me altogether so I just follow what is printed on my calendar.
January 1st, is and always has been noted as the Feast of the Circuмcision. But in our bulletin today it is listed as the Octave Day of the Nativity.
Would someone explain to me why it is different this year?
