Cyril and Methodius were brothers who evangelized the Khazars, Bohemians, and Moravians in the 9th century, and with the permission of the Pope, translated the Liturgy and Bible into the Slavonic language. They invented the Cyrillic alphabet.
The Feast of Saint Valentine was celebrated yearly on February 14th in the Roman calendar from a.D. 496 until the calendar reform of 1969, and commemorates a Roman priest-martyr, buried on the Via Flaminia, the road that goes between Rome and Ravenna.
In honor of the Saints:
I'm just not good at it.
