The Analog Algorithm

A solar calendar encoded in 52 cards.
Pure mathematics. No computers. No astrology.

52 cards = 52 weeks. 4 suits = 4 seasons. The Joker encodes the exact 1.25 leap-day correction. Your birth date pins your card to a permanent coordinate. Every year, a single fixed mathematical rule shifts every card — creating a helix through time.

Pure analog mathematics, built before computers existed.
