Natural Family Planning Awareness Week is a national educational campaign.  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.  For further information:  http://usccb.org/issues-and-action/marriage-and-family/natural-family-planning/awareness-week/index.cfm.
