The 13 cards in each suit represent the 13 phases of the lunar cycle.
What? New moon, waxing crescent, waxing half, waxing gibbous, full, waning gibbous, waning half, waning crescent: eight phases. What are the other five?
Finally, adding up all the numbers in each and every card the result is 365 – the number of days in a year.
No it isn't. 365 isn't even, let alone divisible by four.
1+2+3+4+5+6+7+8+9+10 = 55; 55 * 4 = 220.
Even if we say that Jack = 11, Queen = 12 and King = 13, you get (55 + 11 + 12 + 13 ) * 4 = 364, not 365.
Close but no cigar.
