No Vigil Mass this year for St Patrick's Day
Because this year the 16th of March falls on the second Sunday of Lent - which holds a very high status in the Liturgical Calendar - Masses for the Solemnity of St Patrick will only take place on Monday 17th. If you take a look at page 60 of the "Liturgical Calendar for Ireland 2014", you'll see that the Evening Prayer on 16th March is given as that of the Second Sunday of Lent. That indicates to us that the Evening Mass on 16th March is also that of the Second Sunday in Lent and is NOT to be a Vigil Mass anticipating the Solemnity of St Patrick.
