The PCA takes a nuanced approach to Christian holidays: Christmas and Easter are widely observed and celebrated by many PCA congregations as commemorations of Christ's incarnation and resurrection. However, the PCA does not mandate these observances, maintaining the Reformed regulative principle (worship must be warranted by Scripture).

The PCA also marks other seasons—Advent, Pentecost—though without the liturgical rigidity of liturgical churches. The concern is that holidays not become occasions for superstition, error, or the displacement of biblical authority. Congregations are free to observe or not observe these days according to conscience, provided biblical truth is maintained.

The PCA opposes the veneration of saints and the doctrine that particular days have intrinsic spiritual power. While holidays can be occasions for teaching and worship, they are not obligatory, and the regulative principle ensures that worship practices are subject to biblical scrutiny. Pastors are encouraged to use holidays as teaching opportunities while respecting the liberty of conscience.
