Feast Day Of Saint Phillip And Saint James - 11 May

Quoted from thenalc.org [1]:

May 1 has been kept as the feast day of St. Philip and St. James since ca. 560 when on May 1 the supposed remains of the two saints were interred in the new Church of the Holy Apostles in Rome....

To acknowledge the twentieth-century dedication of May 1 to labor and the working classes, Pope Pius XII in 1955 made May 1 the Feast of St. Joseph the Worker, and shifted the feast of Philip and James to May 11; the present Roman calendar (1969) moved the commemoration of the two apostles to May 3, closer to the original date.

Quoted from My Catholic Life! [2]:

In the sixth century, Pope Pelagius I traveled to Constantinople and brought the relics of the Apostles Philip and James back to Rome, placing them in what is today called the Church of the Holy Apostles. It is for this reason that we honor these two Apostles together with one feast.

Quoted from Loyola Press [3]:

Philip and James were both apostles, and both served Christ faithfully during the very early days of the Church.

Philip seems to have been an enthusiastic person. He was the one who brought his friend Nathanael to Jesus, insisting to Nathanael that he had found the person about whom Moses had written. Some years later it was Philip who made arrangements, with the help of Andrew, to have a group of Greek Gentiles brought to Jesus. ... Philip also had a practical, down-to-earth mind. He was the apostle who commented that it would take a considerable amount of money to feed a crowd of more than 5,000 hungry men, women, and children. It was Philip who asked to see the Father when Jesus spoke about him at the Last Supper.

James was the son of Alphaeus and seems to have been born in Caesarea. He is mentioned less frequently in the New Testament than Philip is. Sometimes James is called the Less, which might be a hint that he was a short person or else that he was younger than the other apostle named James.

After Jesus’ death James continued to preach the Gospel and is believed to have become the first bishop of Jerusalem. Assuming that James and the first bishop of Jerusalem are one and the same person, then he met his death as a martyr in that city about the year a.d. 62. Tradition identifies James as the author of the epistle associated with his name.
