Do you observe Ash Wednesday?

In the Western Christian calendar, Ash Wednesday is the first day of Lent and occurs forty days before Easter (excluding Sundays). It falls on a different date each year, because it is dependent on the date of Easter; it can occur as early as February 4 or as late as March 10.

At Masses and services of worship on this day, ashes are imposed on the foreheads (or tonsure spots, in the case of some clergy) of the faithful. The priest, minister, or in some cases officiating layperson marks the forehead of each participant with black ashes in the shape of a cross, which the worshiper traditionally retains until washing it off after sundown. The act echoes the ancient Near Eastern tradition of throwing ash over one's head to signify repentance before God (as related in the Bible).
