Anglican churches observe Sunday as the Lord's Day, the day of Christ's resurrection, and expect regular Sunday worship as a central duty of Christian life. The Book of Common Prayer provides Daily Morning and Evening Prayer services and Sunday Eucharistic services as the normative pattern of Anglican worship. The Thirty-Nine Articles (Article XXXIV) allow for variation in traditions and ceremonies but the universal practice has been Sunday worship.

Anglicanism does not enforce the strict Puritan-Reformed Sabbatarianism that treats Sunday as the Christian Sabbath requiring rest from all worldly activity. Nor does it regard the Jewish Sabbath (Saturday) as binding on Christians. Sunday is observed as an evangelical freedom — the day the church has customarily gathered for Word and Sacrament — rather than as a legal obligation derived from the Fourth Commandment. The Prayer Book's cycle of Daily Prayer has historically encouraged not just Sunday but daily devotional practice.
