Thank y'all for responding
Melvis: You've explained it well; thank you
With The Fool card, you are correct about it being regarded as the 22nd card.
I use the following guideline:
If the birthdate results in 4, The Emperor is both Personality & Soul Card; 13-Death, Shadow Card; 22/0-The Fool is also a Shadow Card.
If the birthdate results in 22, then 22/0-The Fool is the Personality; 4-The Emperor is the Soul;13-Death, the Shadow.
If the Personality is 13-Death, the Soul is 4-The Emperor; 22/0-The Fool is Shadow.
Any 2-digit number in excess of 22 is reduced because there are 22 Major Arcana.
As mentioned earlier, the Personality Card indicates those lessons to be learned in the life. All minor arcana cards represent aspects of the Major Arcana & as such, the pip cards act as Lessons & Opportunities Cards to the Personality Card. For example, if 4-The Emperor is the Personality Card, all number 4 cards would be used in this manner. When one examines those aspects or influences along with any of the Lifetime Cards, much can be learned, especially as they appear in daily cards or spreads.
Happy calculating, All!
