13 cards per suit = seasons Winter, Spring, Summer, Fall...or/and 13-28 day lunar cycles per year...and 13 weeks per 90 degrees around the sun(1/4 lap)
26 per color = equinox.....or/and 180 degrees around the sun(1/2 lap)=26 weeks
52 cards per deck = weeks per year
interesting stats on the shuffle...assigning meaning to numbers could be a bit subjective unless the person who designed it says that's what he was up to.
