Card game enthusiasts know this curious fact well: a 52-card deck has 4 suits (like the 4 seasons), 12 face cards (like the 12 months), and if you add up all the card values, with jacks worth 11, queens 12, and kings 13, you get exactly 365—the number of days in a year. With two jokers, the total rises to 366, as in a leap year.
