The day when people show their affection for another person or people by sending cards, flowers or chocolates with messages of love and affection.
But, who was St Valentine?
The day gets its name from a famous saint, but there are many stories about who he was.
The popular belief about St Valentine is that he was a priest from Rome in the third century AD. Interesting!
So how did it all start? Having a particular Valentine's Day is a very old tradition, thought to have originated from a Roman festival called Lupercalia in the middle of February - officially the start of their springtime. Yes! We need Spring!!!
It's thought that as part of the celebrations, boys drew names of girls from a box. They'd be boyfriend and girlfriend during the festival and sometimes they'd get married. Gosh, that’s quick!
Later on, the church wanted to turn this festival into a Christian celebration and decided to use it to remember St Valentine too.
Gradually, St Valentine's name started to be used by people to express their feelings to those they loved.
Let’s face it, whatever the origin, it’s lovely to receive a card or too!!
