Feast Of Saints James and Phillp - 1 May (11 May)

Quoted from ¡Viva Cristo Rey! [1]:

Philip was, like Peter and Andrew, a native of Bethsaida, in Galilee. He preached the Gospel to the Scythians, and suffered martyrdom, crucified, in Hierapolis, around the year 80. James the Lesser was the Lord’s first cousin. He was the first Bishop of Jerusalem, and wrote a canonical epistle named after him. He suffered hasty martyrdom from a temple gallery, and his head was crushed with a mace.

The Roman Catholic Daily Missal, 1962, Angelus Press, also uses May 11 for this feast.  Mass readings begin on page 1201.

Other sources indicate that Feast of Saints James and Philip falls on the second Sunday after Easter which in 2022 is May 1. [2]
