The Office this month
Texts of the season
The season is currently Eastertide, and the Ordinary texts for the season are set out in the 'of time section of your Office book. After the feast of the Ascension on May 18 the Ordinary changes to those for Ascensiontide.
May 1 and the feast of St Joseph
May 1 is designated as the feast of St Joseph the Worker in the 1962 calendar, however as this feast now looks very outdated, many monasteries have adopted the option to say instead the Office of the former Solemnity of St Joseph (previously said on the Wednesday of the second week after the Octave of Easter).
The texts for the Solemnity of St Joseph can be found at page [130] and following in the Monastic Diurnal; page 883 in the Antiphonale; and page 992 and following in the new Nocturnale Monasticum.
The former Solemnity also had an octave, with three patristic readings each day at Matins.
May 3: Finding of Holy Cross
A number of monasteries have also revived the Feast of the finding of Holy Cross, on May 3, for which see page 896 of the Antiphonale and 998 in the Nocturnale.
The texts for the day hours are the same as for the feast of the Exaltation of Holy Cross on September 14, which can be found at page [265] and following in the Monastic Diurnal, with the exception of the canticle antiphons and collect (which you can find on Divinum Officium).
May 6: St John before the Lateran Gate
The feast of St Joh is another secondary feast suppressed in the 1962 calendar, but being revived in a number of places. The necessary texts and chants for it can be found in the Antiphonale from page 904.
Octave of the Ascension
The most important twentieth century calendar change affecting this period was the suppression of the Octave of the Ascension.
The texts previously used are mostly preserved as the 'Ordinary of Ascensiontide' however where the former Octave is celebrated, on weekdays up until Wednesday: at Matins, there are three Patristic readings of the Octave; and at Lauds to Vespers, all is as for the feast.
On the Friday after the Octave, the Office is said as for the Sunday within the Octave (ie as per the ‘Office in Ascensiontide’ 1962 rubrics) unless displaced by a Class I or II feast (in which case the Octave is commemorated).
