In the United States and other countries, the bishops have received permission from the Vatican to abrogate (temporarily waive) the requirement for Catholics to attend Mass on certain Holy Days of Obligation, when those Holy Days fall on either Saturday or Monday. Because of this, some Catholics have become confused about whether certain Holy Days are, in fact, Holy Days of Obligation. All Saints Day (November 1) is one such Holy Day.
Of course, even in those years when we aren't required to attend, celebrating All Saints Day by attending Mass is a wonderful way to honor the saints, who constantly intercede with God for us.
