Pythagorean numerology

/v1/numerology/pythagorean follows the rules Hans Decoz publishes. This is a modern Western system and nothing Pythagoras wrote. The other numerology operations stay Chaldean.

Numerologists disagree on methods, so these are the choices:

• Letters: A=1 to I=9, J=1 to R=9, S=1 to Z=8. Accents are removed. A name without Latin letters is refused.
• Life path: month, day and year are reduced separately, keeping 11, 22 and 33, then added and reduced. This is Decoz's Method A. Adding all the digits together can give a different answer.
• Name numbers: each name is reduced by itself, then the results are added. Send the full name at birth, without titles or suffixes.
• Y: a vowel, unless it follows a vowel or starts a name before one (Maya, Yemen). W is always a consonant. There is no override for a single letter.
• Karmic debt: 13, 14, 16 or 19 met while reducing the life path, expression, soul urge or personality, plus a birthday on one of those days and the digit sum of the birth year. The source does not spell out the rule for names, so applying it there is our reading.
• Pinnacles: the first ends at 36 minus the life path, with a master counted as its single digit. The next two last nine years each, and to_age is null on the last.
• Challenges: master numbers are reduced first. main is the third challenge.
• Personal year and month: from as_of, by calendar year, reduced to one digit. Personal day is left out because the pages give no rule.

The source does not give meanings in a form we can reuse, so meanings come from our own number table, shared with the Chaldean operations and without its planets. Answers are in English only.
