March for Life
- 22 January 1973: date of the Roe vs. Wade decision by the U.S. Supreme Court.
- The "March for Life" in Washington, D.C., is organized on or near that date. The organizers never want the March to take place on a weekend; they want the marchers to have access to their representatives in the House and Senate.
- The U.S. Bishops have made 22 January a "Day of Prayer for Legal Protection of Unborn Children."
- "In all the dioceses of the United States of America, January 22 (or January 23, when January 22 falls on a Sunday) shall be observed as a particular day of penance for violations to the dignity of the human person committed through acts of abortion, and of prayer for the full restoration of the legal guarantee of the right to life. The Mass "For Peace and Justice" (no. 22 of the "Masses for Various Needs") should be celebrated with violet vestments as an appropriate liturgical observance for this day" (General Instruction of the Roman Missal, no. 373).
