Fun Math Fact About a Deck of Playing Cards

I don’t know where this came from but found it to be super interesting.
Did You Know this – about card playing?
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!

Citation Audit

A citation is a listing online that includes your business name, address and phone number – also referred to as an NAP. Your citation listings that appear online need to be accurate – even down to the suite number. A typo on a listing on another website where your phone number or name is incorrect can affect your search rankings and/or even direct traffic to your website.

What is our recommended solution? We will check your NAP details on directories where your citations appear. We will search on Google for the following NAP related items:

Another alternative is to search for citations by looking for citation directories. We review the top directories and niche/local directories to validate your listings. Some of the main directories include Google, Yelp, Yellowpages, CitySearch, Superpages, and DexKnows.

We can also claim listings for your business in case they have not been claimed already. This process will ensure that you are given access to edit and update your listings going forward
