I don’t remember where I discovered this about card playing.

Did you know that the Chinese invented playing cards in AD 1000?

The traditional deck of the playing cards is a strikingly coherent form of a calendar.

  • 52 weeks in the year (52 playing cards in a deck).
  • 13 weeks in each season (13 cards in each suit).
  • 4 seasons in a year (4 suits in the deck).
  • 12 months in a year (12 court cards). (i.e. Jack, Queen, King in each suit.)

– The red cards represent Day, while black cards represent the Night.
– Jacks = 11, Queens = 12, and the Kings = 13, then add up all the sums of 1 + 2 + 3 + …to 13 = 91.
– Multiply this by 4, for the 4 suits, therefore 91 x 4 = 364.
– Add 1 that is the Joker and you will arrive at the number 365 being the days in a year?

Is this construct a mere coincidence or the sign of great intelligence?

Of interest is the sum of the letters in all the names of the cards, e.g., add up the letters in “one, two, three, four, five, six, seven, eight, nine, ten, Jack, Queen, King” = 52!

  • The Spades indicated ploughing or working.
  • The Hearts indicated love for the crops.
  • The Diamonds indicated reaping the wealth.
  • The Clubs indicated protection and growth.

Also, in some card games 2 Jokers are used – indicating the Leap year.
This mathematical perfection is mind blowing!
