Above is the image known as the Wheel of the Lords of the Days. This astrological wheel integrates multiple systems, which are described below from innermost to outermost circle:

• The four suits and four princesses of the Tarot
• The seven classical planets
• The 36 decans, numbered 1 through 36
• The Roman numerals II to X, representing the Sefirot from Chokmah to Malkuth
• Planetary symbols associated with each Sefirot:
  • II - Uranus
  • III - Saturn
  • IV - Jupiter/Neptune
  • V - Mars
  • VI - Sun
  • VII - Venus
  • VIII - Mercury
  • IX - Moon
  • X - Earth
• The planets in order from the Sun, with the Moon at the end:
  • II - Mercury
  • III - Venus
  • IV - Mars
  • V - Jupiter
  • VI - Saturn
  • VII - Uranus
  • VIII - Neptune
  • IX - Pluto
  • X - Moon (Sun I and Moon X form a dualistic pair)
• The dates attributed to each decan (all months rounded up to 30 days each)
• The seven classical planets matched with their traditional Tarot decan attributions
• The zodiac signs
• Their associated Tarot cards
• The Thoth Tarot cards associated with each decan (e.g., 25 is "Dominion," the Two of Wands)
• The court cards (King, Queen, Prince) aligned with their zodiac signs in the outermost ring
• The elements of each quadrant

Experiment in prediction - a tale of two systems

Of interest are the Thoth tarot associations of the decans with the Roman numeral systems, the planets in order and the planets matched with the sefirot.
