In the Western Christian church, the seventh Wednesday before Easter marks the beginning of the Lenten season. The name is taken from a practice of putting ashes on the foreheads of penitent believers as a reminder of their physical return to dust (“ashes to ashes”). The practice is common among Roman Catholics, Anglicans and Episcopalians, and many Lutherans. It is also becoming more popular among other Protestant churches.
