The month of January is traditionally dedicated to the Holy Name of Jesus. The Liturgical Calendar at Catholic Culture has some helpful information on today's feast day:

Today the Church celebrates the optional memorial of the Most Holy Name of Jesus. According to the 1962 Missal of Bl. John XXIII the Extraordinary Form of the Roman Rite this feast is celebrated on January 2. In the liturgical revisions of Vatican II, the feast was removed, though a votive Mass to the Holy Name of Jesus had been retained for devotional use. With the release of the revised Roman Missal in March 2002, the feast was restored as an optional memorial in the Ordinary Form on January 3.

The Church reveals to us the wonders of the Incarnate Word by singing the glories of His name. The name of Jesus means Savior; it had been shown in a dream to Joseph together with its meaning and to Our Lady at the annunciation by the Archangel Gabriel.

Devotion to the Holy Name is deeply rooted in the Sacred Scriptures, especially in the Acts of the Apostles. It was promoted in a special manner by St. Bernard, St. Bernardine of Siena, St. John Capistrano and by the Franciscan Order. It was extended to the whole Church in 1727 during the pontificate of Innocent XIII. The month of January has traditionally been dedicated to the Holy Name of Jesus.

According to the 1962 Missal of Bl. John XXIII the Extraordinary Form of the Roman Rite, the feast of the Holy Name of Jesus which is kept on the First Sunday in the year; but if this Sunday falls on January 1, 6, or 7, the feast is kept on January 2.

The New Advent Encyclopedia tells us:

• The Name of Jesus invoked with confidence
  • brings help in bodily needs, according to the promise of Christ: "In my name They shall take up serpents; and if they shall drink any deadly thing, it shall not hurt them: they shall lay their hands upon the sick, and they shall recover". (Mark 16:17-18) In the Name of Jesus the Apostles gave strength to the lame (Acts 3:6; 9:34) and life to the dead (Acts 9:40).
  • It gives consolation in spiritual trials. The Name of Jesus reminds the sinner of the prodigal son's father and of the Good Samaritan; it recalls to the just the suffering and death of the innocent Lamb of God.
  • It protects us against Satan and his wiles, for the Devil fears the Name of Jesus, who has conquered him on the Cross.
  • In the Name of Jesus we obtain every blessing and grace for time and eternity, for Christ has said: "If you ask the Father anything in my name he will give it you." (John 16:23) Therefore the Church concludes all her prayers by the words: "Through Our Lord Jesus Christ", etc.
  So the word of St. Paul is fulfilled: "That in the name of Jesus every knee should bow, of those that are in heaven, on earth, and under the earth" (Phil., ii, 10).

From the Catechism of the Catholic Church, we read:

• 2666 But the one name that contains everything is the one that the Son of God received in his incarnation: JESUS. The divine name may not be spoken by human lips, but by assuming our humanity The Word of God hands it over to us and we can invoke it: "Jesus," "YHWH saves" (cf. Ex 3:14; 33:19-23; Mt 1:21). The name "Jesus" contains all: God and man and the whole economy of creation and salvation. To pray "Jesus" is to invoke him and to call him within us. His name is the only one that contains the presence it signifies. Jesus is the Risen One, and whoever invokes the name of Jesus is welcoming the Son of God who loved him and who gave himself up for him (Rom 10:13; Acts 2:21; 3:15-16; Gal 2:20).
