The CRCNA observes the major Christian holidays, particularly Christmas (the incarnation of Christ), Easter (the resurrection), Ascension Day (Christ's return to heaven), and Pentecost (the gift of the Spirit). These are understood as celebrations of the central redemptive events of the Christian faith and are incorporated into the CRCNA's liturgical life and corporate worship.

Unlike some evangelical churches that minimize liturgical observance, the CRCNA has historically maintained a more formal liturgical tradition influenced by its Reformed heritage. The church year is marked by these major feasts, and sermons and prayers are often shaped by the themes of the season. The Heidelberg Catechism (Q&A 102) affirms that the Lord's Day (Sunday) is the chief day of worship, but the CRCNA extends this to include recognition of other important Christian commemorations throughout the year.

The CRCNA has not mandated observance of Advent or Lent with the same strictness as liturgical traditions, but these seasons are increasingly recognized in CRCNA worship. The denomination's Book of Worship and denominational resources provide guidance for observing the Christian calendar. Individual congregations have freedom to determine their specific practices, but the broad recognition of Christmas, Easter, and other major Christian holidays is affirmed as appropriate and edifying for the church.
