Southern Baptist churches widely observe Christmas (the birth of Christ) and Easter (the resurrection of Christ) as central celebrations in the Christian year. These are treated as occasions for evangelism, family worship, and reflection on the foundational events of the Christian faith. The BFM2000 does not mandate a liturgical calendar, and SBC churches are free to structure their worship and observances according to local tradition and pastoral judgment.

Unlike traditions with a formal liturgical calendar (Anglican, Lutheran, Catholic), most SBC churches do not observe Advent, Lent, or other seasons of the church year as formal practices. However, many SBC churches have adopted some of these practices informally. The denomination has no central worship authority that dictates which days must be observed.

The SBC has at times engaged in cultural debates about holidays — for example, issuing statements on the commercialization of Christmas or criticizing the secularization of Easter. Individual pastors and churches may take varying stances on cultural holidays such as Halloween, with some encouraging alternative Christian celebrations and others taking a neutral stance.
