Matthias the Apostle Feast Day

The feast of Saint Matthias was included in the Roman Calendar in the 11th century and celebrated on the sixth day to the Calends of March (24th February but 25th February in leap years). In the revision of the General Roman Calendar in 1969, his feast was transferred to 14th May, so as not to celebrate it in Lent but instead in Eastertide close to the Solemnity of the Ascension, the event after which the Acts of the Apostles recounts that Matthias was selected to be ranked with the Twelve Apostles.
