The Feast of All Saints is a major holy day in both the Anglican and Catholic churches (as well as several other denominations), celebrated annually on November 1. It is a day dedicated to all the saints of the Church, that is, all those who have attained heaven. Over the centuries, many of these saints have suffered and even died for Our Lord, sustained in life largely by their tenacious faith.

Although millions—or even billions—of people may already be saints, many All Saints' Day observances tend to focus on known saints, those recognized in the canon of the saints by the Church.
