Natural Family Planning Awareness Week is a national educational campaign. The Natural Family Planning Program of the United States Conference of Catholic Bishops develops a poster each year with basic supportive materials. It is the individual dioceses however, that offer a variety of educational formats in the local church to focus attention on Natural Family Planning methods and Church teachings which support their use in marriage.
The dates of Natural Family Planning Awareness Week highlight the anniversary of the papal encyclical Humanae Vitae (July 25) which articulates Catholic beliefs about human sexuality, conjugal love and responsible parenthood. The dates also mark the feast of Saints Joachim and Anne (July 26), the parents of the Blessed Mother.
