St Valentine’s Day comes on February 14. It is not a legal or a national holiday. Banks and offices are not closed, but it is a happy little festival for young people. It is widely celebrated among people of all ages by exchange of “valentines”. A “valentine” may mean a special greeting-card or a little present. It may be for the person who receives the gift. St Valentine is the patron of sweethearts. It is a good day for parties, especially by young people. The hosts trim the hall with red and white paper hearts. Refreshments are often coloured red, like red candy and punch. Sandwiches and cakes are often cut in the shape of hearts. Sometimes, a King and Queen of Hearts are chosen for the evening of dance.
