Valentine's Day is celebrated on February 14.

In the Roman Empire, the day was originally dedicated to the goddess Juno (protector of marriage and family). Flowers were offered to her that day and flowers were given to women. On this high feast day, the young girls also went to the Temple of Juno to get a love oracle for the right choice of partner. Also found on 14./15. The so-called Roman Lupercalia (Festival of the She-Wolf) took place in February, during which the sexual maturity rituals for the first menstruation of girls were held and marriages were concluded after they had reached maturity. The mating season of the birds also begins in mid-February. 

The customs of this day go back to the feast of St. ck, a martyr. According to tradition, Valentine was a poor priest living in Rome in the third century under the anti-Christian Emperor Claudius II. According to legend, he gave flowers from his garden to newlywed couples. In addition, the marriages that were concluded through him are said to have always been under a lucky star. Valentin also married soldiers who, according to imperial orders, had to remain unmarried, according to Christian ceremonial. This was probably the reason why Valentin was beheaded in Rome on February 14, 269 by order of Emperor Claudius II and thus became a martyr. Saint Valentine is considered the patron saint of lovers, engaged couples and beekeepers.

St. Valentinus on February 14 was instituted by Pope Gelasius in 469 for the whole Church, but was removed from the Roman general calendar in 1969. There are common services around Valentine's Day where couples are blessed.
