Pinnacles in numerology

Pinnacles are four long stretches of a life in Western numerology, each with its own number and focus. The API ends the first at age 36 minus the life path digit. The next two last nine years each, and the fourth runs for the rest of life. John Doe's four pinnacles are 5, 7, 3 and 9.

Pinnacles: how the API works it out

The API reduces the month, the day and the year of birth, keeping master numbers. The first pinnacle adds the month and the day. The second adds the day and the year.

The third adds the first two pinnacles, and the fourth adds the month and the year. Each sum is reduced again, with 11, 22 and 33 kept. Books differ on when the stretches change.

The API ends the first pinnacle at age 36 minus the life path digit. The next two last nine years each, and the fourth runs for the rest of life. This is stated in basis.pinnacles.

John Doe was born August 15, 1990, and his life path is 6. So his first pinnacle, 5, runs from birth through age 30, until his 31st birthday in August 2021. His second, 7, runs from age 31 to 39.

The third, 3, runs from 40 to 48, and the fourth, 9, from 49 on. POST /v1/western returns them under pinnacles.items. Each item has id, number, digit, from_age, to_age, from_year and to_year.

The fourth has null for its end. The current field marks the stretch running on the as_of date, which defaults to today. On October 1, 2026, that is John Doe's second pinnacle.

Each reading is the general entry for its number.
