Valentine's Day facts

1. There are two theories about Valentine's Day origins - one is that the day derives from the Roman festival Lupercalia. Held between February 13-15, the events that took place at the festival were hoped to improve fertility and became associated with being a couple.
2. The second theory suggests two men named Valentine began the tradition. Roman Emperor Claudius II forbade young men to marry while trying to build his army, accusing women of being a distraction. The first Valentine defied the ban and continued to perform secret marriages - he was executed for his crimes on February 14 in roughly the year 270 A.D.
3. The second Valentine is thought to have been killed for attempting to help Christians escape prison in Rome. When imprisoned himself, it's thought he sent the first ever Valentine's card - a message to himself, signed "From your Valentine." The combined antics of the Valentines were thought to have originated the celebration.
4. As the legend of Valentine was passed through history, it became customary for lovers to exchange notes and mementos on February 14, repeating the original signature  "From your Valentine."
5. Nobody knows which one of the Valentine's Day origin theories is real, if any. 
6. In 496 A.D., it was Pope Gelasius I who made the feast of St. Valentine an official holiday.
7. The celebration didn't become associated with romance until the Middle Ages. This is thought to stem from French and English beliefs that birds began their mating season on February 14.
8. The idea of birds mating on February 14 originated from Geoffrey Chaucer's poem "The Parliament of Fowls," published around 1381 - 1382. In the poem, he alludes to birds choosing mates on Valentine's Day, altering the connotations of the holiday to one of a romantic nature.

9. The oldest verified record of a Valentine being sent, was in 1415. A French duke named Charles sent a poem to his wife while imprisoned in the Tower of London at the tender age of 21.
10. A line of the poem read "I am already sick of love, My very gentle Valentine."
11. The phrase "Wearing your heart on your sleeve" also derives from the Middle Ages - during this period, men and women drew names to see who their Valentine would be for the Roman festival Juno. They would pin the name to their sleeve to show the identity of their love interest for the coming year, quite literally wearing their heart on their sleeve.
12. The use of "X" as a kiss when signing off also derived from the Middle Ages. Many people used X as a signature anyway as they couldn't write. At the time, Christians kissed statues of Christ and the X evolved into a sign off that was both a signature and a kiss.
13. In 1537, King Henry VIII declared February 14 as the official holiday of St. Valentine's Day by royal charter.
14. In 1969, Pope Paul VI removed St. Valentine's Day from the calendar of major holidays, because it was so difficult to verify anything about the actual St. Valentine.
15. Despite being removed from the official calendar of major events, its religious observance is still permitted.
16. In the 1700s, English women would pin five bay leaves to their pillows on the evening of February 13. Placing one in the middle and on each four corners, they believed this would induce dreams about their future husbands.

24. Over 250,000 roses are grown in time for being given as Valentine's Day gifts.
