original meaning of a deck of playing cards: 52 cards for 52 weeks in the year. 2 colors for day and night 4 suits for the 4 seasons and 13 weeks per season. Twelve court cards representing the 12 months. If we add each of the cards (ace + ace + ace + ace + two + two + three + seven + eight ... and etc) of the game we will get 364. The card game is an agricultural calendar that told us about the weeks and the seasons. With each new season, it was King's week, followed by Queen's week, Jack's and so on until AS week changed seasons and we started over with a new color. Jokers were used in leap years. And you, did you know it?
