Today, 28 December, is Card Playing Day – the day to celebrate all games involving your classic deck of cards.
When you think about it, a deck of cards is a pretty impressive creation – the diversity and complexity covered in all the games using a card deck is quite staggering. From games testing cunning and deception (poker), to games teaching teamwork and planning (bridge), to those based on statistical probability and counting skills (blackjack), to visual pattern-matching games (rummy), to the single-player solitaire/patience type games, and hundreds more in-between, the options are almost limitless. And all this based on a simple collection of 52 playing cards, involving four different ‘suits’ of 13 cards each.
Playing cards have a long history – they were first found in China as early as the 9th century, and appeared in Europe around the 14th century. The first card decks containing the now-standard 52 cards consisted of suits with themes like polo sticks, coins, swords and cups. The famous suits of spades, hearts, diamonds and clubs, as we still use today, was first introduced in France around 1480. The Kings, Queens and Knaves (Jacks) in the different suits were based on English and French history, and referred to different historical characters such as King David, Julius Caesar, Alexander the Great, and others.
Beyond the historical connotations, a range of symbolic meanings are attached to the deck of cards as we know it. The 13 cards in each suit is said to refer to the 13 months of the lunar year; the 52 cards corresponds to the 52 weeks in a year; the Ace, which is both the lowest and highest card in each suit, is symbolic of the beginning and end, alpha and omega.
From a scientific point of view, playing cards represent an invaluable demonstration and teaching aid in fields such as mathematical logic, probability and statistics.
Whether you enjoy playing cards for the thrill and uncertainty of games of chance, or because of the complex mathematics they represent, or simply because of the social interaction inherent in many card games, today is the day to celebrate all facets of card playing. So while you’re enjoying that pleasant lull between Christmas and New Year, why not pull out a deck of cards – play an old game, learn a new one, and lose yourself in the mathematical complexities hidden in your standard card deck.
