About this calculator
This is a traditional numerology reading, not an evidence-based assessment or prediction. The selected method reduces the birth date either by reducing day, month and year separately or by reducing their combined digit sum. Master numbers 11, 22 and 33 can be retained when enabled.
Worked example
calculated with the default values below
Date of birth 1990-06-15 · Keep master numbers Yes (11, 22 and 33) · Total method Reduce day, month and year separately Life path number 4 · Day number 6 · Month number 6 · Year number 1 · Traditional meaning The builder — practical and dependable · Note Numerology is a traditional practice, not an evidence-based assessment

Formula and variables
s(n) = Σᵢ dᵢ, n = Σᵢ dᵢ × 10ⁱ, dᵢ ∈ {0,…,9}; r(n) = {n, n ≤ 9 ∨ n ∈ M; r(s(n)), n > 9 ∧ n ∉ M}; L = r(r(day) + r(month) + r(year))
- day

- year
- birth year
- r

- L
- life path number
- s
- digit sum, s(n) = Σᵢ dᵢ
- d
- digit of n, dᵢ ∈ {0,…,9}
- M
- master-number set: {11,22,33} when kept, ∅ otherwise
The separate method reduces date components independently before adding them; all-at-once reduces their combined sum. If enabled, 11, 22 and 33 are retained. Numerology is traditional entertainment, not an assessment.
Frequently asked questions
How do the two calculation methods differ?
The separate method reduces the day, month and year individually before adding them. The all-at-once method reduces their combined sum. Keeping master numbers preserves 11, 22 and 33; numerology is a traditional practice, not an evidence-based assessment.
