On the Feast of this most wonderful of Saints, your priest might bless lilies for you to keep (this isn't a universal practice). The blessing of lilies, which remind us of St. Anthony's purity and have always been a symbol for him, stems from a miracle which took place in Revolutionary France: many priests and religious were murdered, so many churches and convents destroyed, but the faithful still showed up at a surviving church on the Feast of St. Anthony. Months later, it was discovered that lilies that had adorned the church at that feast were still fresh. Let the lilies beautify your house, or carry them with you, or press them in a book, etc. If your priest doesn't bless lilies, you can still use them non-sacramentally to remind you of one of the greatest Saints ever.In some parishes, chapels, or countries, animals might be blessed today as they are also sometimes blessed on the Feasts of St. Anthony Abbot and of St. Francis of Assisi.
Another custom on this day is known as "St. Anthony's Bread" and goes back to A.D. 1263 when a child drowned near the Basilica of St. Anthony in Padua as it was still being built. The mother besought St. Anthony and promised that if her child were restored to life, she would give to the poor an amount of wheat equal to the weight of her child. Of course her son was saved, and her promise was kept. "St. Anthony's Bread," then, is the promise of giving alms in return for a favor asked of God through St. Anthony's intercession (the custom also takes place throughout the year when parents give alms after placing their baby under the patronage of St. Anthony). In some places, the custom has a literal parallel in that loaves of bread might be blessed and given away at church or, generally, to the poor.
Because of St. Anthony's history of being invoked by single women in search of a husband, today is a good day for single people who have a vocation to marriage to make a visit to a church or shrine dedicated to St. Anthony!
In Lisbon, his birthplace, it is a traditional day for getting married (women who get married on this day are called "brides of St. Anthony"). So popular are weddings on this day in Lisbon, that the city hall hosts them for free if the couple are poor. St. Anthony altars are built and decorated, parades are held, bonfires lit, grilled sardines and sangria are enjoyed.

Pentecost is one of the prominent feasts in the Christian liturgical year commemorating the descent of the Holy Spirit upon the disciples of Christ after the Resurrection.The feast is also called Whit Sunday, Whitsun, or Whit especially in the United Kingdom, where the following Monday was traditionally a holiday. Pentecost is celebrated seven weeks (50 days) after Easter Sunday, hence its name.Pentecost falls on the tenth day after Ascension Thursday.

Pentecost is historically and symbolically related to the Jewish harvest festival of Shavuot, which commemorates God giving the Ten Commandments at Mount Sinai fifty days after the Exodus. Among Christians, Pentecost commemorates the descent of the Holy Spirit upon the Apostles and other followers of Jesus as described in the New Testament Acts of the Apostles 2:1-31. For this reason, Pentecost is sometimes described as the "Birthday of the Church".

In other places, particularly Sicily and the Italian peninsula, rose petals were and are thrown from the galleries over the congregation calling to mind the tongues of fire. In modern times, this practice has been revived, and interestingly adapted as well, to include the strewing of origami doves from above, or suspending them – sometimes by the hundreds – from the ceiling. In some cases, red fans, or red handkerchiefs are distributed to the assembled worshippers to be waved during the procession, etc. Other congregations have incorporated the use of red balloons, signifying the “Church’s Birthday” into their festivities. These may be carried by worshippers, used to decorate the sanctuary, or released all at once.

Paul already in the 1st century notes the importance of this festival to the early Christian communities. (See: Acts 20:16 & Corinthians 16:8) Since the lifetime of some who may have been eye-whitnesses, annual celebrations of the descent of the Holy Spirit have been observed. Before the Second Vatican Council Pentecost Monday as well was a Holy Day of Obligation during which the Catholic Church addressed the newly baptized and confirmed. Since that time however Pentecost Monday is no longer solemnized.

The Feast of the Ascension of Jesus is a Holy Day of Obligation.  Holy days of obligation are feast days on which Catholics are required to attend Mass and to avoid (to the extent that they are able) servile work.

The Ascension of Jesus is the Christian teaching found in the New Testament when the resurrected Jesus was taken up to heaven in his resurrected body,^{[Acts 1:9-11]} in the presence of eleven of his Apostles, occurring 40 days after the resurrection. Jesus ascended to his Father and his heavenly throne, and now sits at the right hand of God the Father in heaven. An angel told the watching disciples that Jesus' second coming would take place in the same manner as his ascension, that is, He would descend in bodily form. This is also described in other Biblical passages.

The Ascension of Jesus is professed in the Nicene Creed, which is spoken in the Christian liturgy, and in the West, by the Apostles' Creed. The Ascension implies Jesus' humanity being taken into heaven. The Feast of the Ascension, celebrated 40 days after Easter, is one of the chief feasts of the Christian year.

Good Friday, the Friday before Easter, commemorates the Passion and Death of our Lord Jesus Christ on the Cross. No Mass is celebrated on Good Friday; instead, the Church celebrates a special liturgy in which the account of the Passion according to the Gospel of John is read, a series of intercessory prayers (prayers for special intentions) are offered, and the faithful venerate the Cross by coming forward and kissing it. The Good Friday liturgy concludes with the distribution of Holy Communion . Since there was no Mass, Hosts that were reserved from the Mass of the Lord's Supper on Holy Thursday are distributed instead.

Maundy Thursday, also known as Holy Thursday, is the Christian feast or holy day falling on the Thursday before Easter that commemorates the Last Supper of Jesus Christ with the Apostles as described in the Canonical gospels. It is the fifth day of Holy Week, and is preceded by Holy Wednesday and followed by Good Friday. The Mass of the Lord's Supper initiates the Easter Triduum, the three days of Good Friday, Holy Saturday and Easter Sunday that commemorate the Passion, Death and Resurrection of Jesus. It is normally celebrated in the evening, when according to Jewish tradition Friday begins.

The Washing of the Feet is a traditional component of the celebration in many Christian Churches, including the Armenian, Ethiopian, Eastern Orthodox, Eastern Catholic, Schwarzenau Brethren/German Baptist groups, Mennonites, and Roman Catholic Churches. In the Roman Catholic Church, the Mass of the Lord's Supper begins as usual, but the Gloria is accompanied by the ringing of bells, which are then silent until the Easter Vigil. After the homily the washing of feet may be performed. The service concludes with a procession taking the Blessed Sacrament to the place of reposition. The altar is later stripped bare, as are all other altars in the church except the Altar of Repose, as a preparation for the somber Good Friday service. In pre-1970 editions, the Roman Missal envisages this being done ceremonially, to the accompaniment of Psalm 21/22, a practice which continues in many Anglican churches.
