Charles, Duke of Orleans
This is another alleged origin of Valentine's Day traditions. Here, Charles sent his wife poems (or cards depending on who's telling the story) during his twenty-four year imprisonment starting in 1415. While he certainly did do this (with much of his poetry surviving to this day), there's no confirmation that this was the inspiration to send cards or poems on Valentine's Day.
Suicide Rates Spike
An oldie but a goodie: suicide rates are said to see a sharp increase around Valentine's Day. However, there isn't much to back this up in terms of actual studies or statistics.
Doesn't Really Exist (Sort Of)
Let's go back to the mystery of St. Valentine. We've covered that there's more than one and we aren't sure which one the big day is named after. But ultimately that's okay because the Catholic church wiped the St. Valentine's Day feast from the Roman calendar in 1969, further distancing the day from any religious connotation.
Since it's a day for romance you'd expect that a lot of pregnancies would result from Valentine's Day “celebrations,” but according to these stats there's no factual basis for this belief. Any spikes in pregnancies following the holiday are slight at best.
The Most Popular Time For Weddings
We've already covered why most women don't want to be married on Feb. 14th, but there are still those who insist that Valentine's Day specifically and February in general are the most popular times to get married in the United States. But neither are true, and in fact the month of June is the most popular month to tie the knot.
