Valentine's Day is celebrated on February 14th and is thought to be connected to the ancient Roman festival of Lupercalia. The holiday's modern traditions are largely attributed to Geoffrey Chaucer, who first linked St. Valentine's Day with romantic love in his poetry.

Valentine's Day was originally a Christian feast day which was associated with Christian martyrs, with the most famous of them being a third century priest called Saint Valentine. His origin story is shrouded in mystery, and even though he was recognised as a saint by the Catholic Church, he was removed from the General Roman Calendar in 1969.
