What is the liturgical calendar, and what are the seasons?

The liturgical calendar is the Church's annual pattern of seasons, Sundays, and feast days. It leads Catholics through the saving mysteries of Christ's life, death, Resurrection, and promised return.

Why the Church has a calendar. Christian worship is rooted in events God accomplished in history. Each year the Church remembers and sacramentally celebrates Christ's work, from the Incarnation and Nativity to the Passion, Resurrection, Ascension, and sending of the Holy Spirit (CCC 1163). These celebrations do not repeat Christ's sacrifice. They make the one saving mystery present in the Church's worship, especially in the Eucharist (CCC 1085).

The principal seasons. The Roman Rite's year follows this basic pattern:

1. Advent, a season of preparation for Christmas and expectation of Christ's return.
2. Christmas Time, celebrating the Nativity, the manifestation of Christ, and His early life.
3. Ordinary Time, focusing on Christ's public ministry, teaching, miracles, and the growth of discipleship.
4. Lent, a forty day season of repentance and preparation for Easter.
5. The Sacred Paschal Triduum, beginning with the Evening Mass of the Lord's Supper, continuing through Good Friday and Holy Saturday, and reaching its summit in the Easter Vigil.
6. Easter Time, fifty days of celebrating the Resurrection, ending with Pentecost.
7. Ordinary Time again, continuing until the next Advent.

Ordinary Time does not mean unimportant time. Its name refers to the numbered, or ordered, weeks in which Christians steadily follow Christ.

The center of the year. Easter is the "Feast of feasts" because Christ's Resurrection is the foundation of Christian faith and hope (CCC 1169; 1 Cor 15:14). The weekly celebration of Easter is Sunday, the Lord's Day, when the Church gathers for the Eucharist (CCC 1166-1167). Every season receives its meaning from the Paschal Mystery.

Feasts, saints, and colors. The calendar also includes solemnities, feasts, and memorials of Mary and the saints. Celebrating the saints proclaims what Christ has accomplished in members of His Body (CCC 1172-1173). Liturgical colors help express each celebration: violet for preparation and penance, white or gold for joy and glory, red for the Holy Spirit and martyrs, and green for Ordinary Time. Rose may be used on Gaudete Sunday and Laetare Sunday.

Follow the calendar at home by reading the Sunday Gospel, observing major solemnities, and placing a simple seasonal symbol near your prayer space. The Church's year gradually forms daily life around Christ rather than around commercial or secular schedules.
