Saint Valentine's Day, often simply Valentine's Day,^[1][2][3] is observed on February 14 each year. Today Valentine's Day is celebrated in many countries around the world, mostly in the West, although it remains a working day in all of them.

The original "St. Valentine" was a liturgical celebration of one or more early Christian saint named Valentinus. Modern romantic connotations were added several centuries later by poets. Several martyrdom stories were invented for the various Valentines that belonged to February 14, and added to later martyrologies.^{[citation needed]} This celebration was deleted from the General Roman Calendar of saints in 1969 by Pope Paul VI.
