The day after Halloween is called All Saints Day. Celebrated on Nov. 1 each year, it is a Christian day of solemnity that is also referred to as Solemnity of All Saints, All Hallows or Hallowmas.
In Western Christian religions, All Saints Day commemorates all saints. The Roman Catholic religion views All Saints Day as a Holy Day of Obligation, which means that attendance at mass is required.
Protestants who observe All Saints Day use it to remember all Christians, both past and present. In addition to remembering all saints on this occasion, Methodists also use this day to remember the deceased members of their local congregations. The names of those who have died during the preceding year may be read aloud and affixed to a plaque.
