Since the folkloristic Society notes, Geoffrey Chaucer cites Valentine's Day and clarifies Feb as now when each bird came there to chose his partner.Therefore, we know how Valentine's Day has been seen as the most intimate day of the year. Nevertheless, the truth is, we do not know much about St.Valentine himself. You will find eleven Valentines commemorated by your Catholic Church, and there have been two other St.Valentines who lived in the time of St.Valentine of Terni. Since his roots are so obscure, he was really removed from your General Ancient Rome Calendar by the Ancient Rome Catholic Church in 1969.
Thus, do not feel bad if you have a crummy Valentine's Day. It won't be worse than being killed, confused with others, and kicked off your general liturgical calendar which is what really happened to the real St.Valentine.
