Paul VI removed Saint Valentine from the General Roman Calendar in the 1969 revision.
The revision followed the Second Vatican Council’s call to bring the calendar’s celebrations into clearer historical focus. Promulgated by Paul VI through the 1969 motu proprio Mysterii Paschalis, it removed roughly 200 saints from the universal calendar, including Valentine and Christopher.
This did not mean the Catholic Church declared Valentine non-existent or invalid as a saint. Saint Valentine remains listed in the Roman Martyrology, the Church’s official catalogue of saints. The 1969 reform simply left his celebration to local calendars rather than requiring it throughout the Roman Rite.
A common mix-up is the date: the calendar was revised in 1969 but promulgated on January 1, 1970. Valentine’s Day also remains observed in other Christian traditions and in some local Catholic communities, while the modern romantic holiday developed through centuries of later custom.
