How NUMERA calculates
Method: Pythagorean, version 3. Every number in the app opens to its full arithmetic.
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |
|---|---|---|---|---|---|---|---|---|
| A J S | B K T | C L U | D M V | E N W | F O X | G P Y | H Q Z | I R |
Letters
Vowels are A, E, I, O and U. W is always a consonant. Y is a vowel when no vowel stands beside it in its name (an option can make it always or never a vowel). Each name is reduced on its own, then the names are added. Accents are set aside; a name in another alphabet is read from the Latin spelling the person chooses, never transliterated automatically.
Reduction and master numbers
Digits are added until one is left. In the core numbers 11, 22 and 33 are master numbers and are kept wherever they appear (an option reduces them). Life Path reduces month, day and year separately before adding them. Masters are never kept in Challenges, Balance or any cycle.
Core numbers
Life Path: month + day + year. Expression: every letter of the birth name. Soul Urge: its vowels. Personality: its consonants. Birthday: the day of the month. Maturity: Life Path + Expression. Attitude: birth month + birth day. Rational Thought: the first name + the birth day. Balance: the initials, reduced to one digit. Karmic Lessons: values no letter carries. Hidden Passion: the value most letters carry. Subconscious Self: 9 minus the number of Karmic Lessons. Karmic Debt: 13, 14, 16 or 19 before the last reduction of Life Path, Expression, Soul Urge or Personality, or as the birth day.
Pinnacles and Challenges
Pinnacles: month + day, day + year, the first two added, month + year (masters kept). Challenges: |month − day|, |day − year|, the difference of the first two, |month − year|, with every part reduced to one digit. The first period runs to age 36 minus the Life Path; the second and third last nine years; the fourth runs for life.
Period Cycles
The birth month, day and year, each reduced. The first period lasts until the first Personal Year 1 on or after the 27th birthday; the second lasts 27 years; the third, for life.
Cycles
Personal year: birth month + birth day + the year (it turns on January 1, or on the birthday as an option). Personal month: personal year + the month. Personal day: personal month + the day. Universal cycles use the date alone. Every cycle ends in 1 to 9.
Dates
Gregorian calendar dates with no time. “Today” is the date in the person’s time zone, so the Personal Day changes at their midnight, daylight-saving days included. A February 29 birthday falls on March 1 in years without one.
