Discover 12 Surprising Facts About Valentine's Day

Valentine's Day, observed annually on February 14, has origins in ancient Rome's pagan fertility festival known as Lupercalia, which involved animal sacrifices and rituals believed to promote fertility. The Christian celebration emerged in mid-February, coinciding with the mating season of birds, hence the association with love.

The day is linked to Saint Valentin, who defied Emperor Claudius II's ban on marriage for young soldiers, marrying couples in secret until his execution. The tradition of exchanging cards began in the 17th century, with mass production starting in 1840.

In the United States, Valentine's Day spending is estimated at $18.2 billion annually, with men averaging $150 and women $74 on gifts. Approximately 220 million roses are sent each year, and 36 million heart-shaped boxes of chocolates are sold.

February is the second most popular month for engagements, following December. The holiday is known as "El Día de los Enamorados" in Latin American countries, celebrating love and friendship.
