What the calculator returns
Astrolium's free Lot of Spirit calculator returns the Hellenistic Lot of Spirit by sign, degree, and whole-sign house, computed with the correct sect-aware formula based on your chart's diurnal or nocturnal status. Inputs are birth date, time, and place; the tool first determines sect by whether the Sun sits above or below the horizon at birth, then applies the day formula (Ascendant + Sun − Moon) or the night formula (Ascendant + Moon − Sun) and reduces the result to the 0–360 range. The output names the Lot's sign, degree, and whole-sign house, plus the lord of Spirit with its own natal house, sign, and condition, and every natal planet making a sign-based aspect (conjunction, sextile, square, trine, opposition) to the lot with exact orb. Math runs on Swiss Ephemeris, accurate to under 1 arc second. Practitioners read Spirit as the action-and-mind counterpart to Fortune, the body-and-fate lot. Free, no account required.
The output is 3 cards:
- The Lot of Spirit. Sign, exact degree, and the house it occupies. The chart wheel marks the lot at its exact position.
- The lord of Spirit. The planet ruling the sign Spirit occupies, with its natal house, sign, and aspects. The lord matters as much as the lot itself.
- Aspects to Spirit. Every natal planet making a sign-based aspect (conjunction, sextile, square, trine, opposition) to the lot, with exact orbs.
The math runs on the Swiss Ephemeris at arc-second precision, the same library Solar Fire and Astro Gold use.
Spirit and Fortune: the mirror pair
The Lot of Spirit is the mirror of the Lot of Fortune. Where Fortune reads the body and what happens to you, Spirit reads action and what you choose. The 2 lots are computed with reciprocal formulas:
| Sect | Lot of Spirit | Lot of Fortune |
|---|---|---|
| Day chart (Sun above horizon) | Ascendant + Sun − Moon | Ascendant + Moon − Sun |
| Night chart (Sun below horizon) | Ascendant + Moon − Sun | Ascendant + Sun − Moon |
The formulas swap the Sun and Moon. As a result, Spirit and Fortune always sit at supplementary distances from the Ascendant, on opposite sides of the chart. The hellenistic tradition treats them as a doctrinal pair: Spirit (solar, what you do) is the active component, Fortune (lunar, what happens) the passive. Brennan walks through the pairing in chapter 17 of Hellenistic Astrology; Schmidt covered it across several Project Hindsight conferences.
The 7 hermetic lots all inherit sect-sensitivity from this same Sun-Moon principle.
How to read Spirit
The Lot of Spirit indicates action, career, vocation, and what the native chooses. It is the chart's primary indicator for vocational direction, that is, what work the soul is structured to take on.
- Identify Spirit's sign and degree. The sign colors how the lot expresses. Spirit in Capricorn reads as structured, slow-building action. Spirit in Sagittarius reads as expansive, teaching, publishing action.
- Identify Spirit's house. Use whole-sign houses for hellenistic work. Spirit in the 10th emphasises public career. Spirit in the 6th emphasises craft and daily work. Spirit in the 9th emphasises teaching, travel, publishing.
- Locate the lord of Spirit. The planet ruling the sign Spirit occupies is the lord. Where the lord sits natally and what aspects it makes are nearly as important as the lot's own placement.
- Note aspects to Spirit. Conjunctions, sextiles, squares, trines, and oppositions from natal planets activate the lot. Apply sign-based aspect rules.
- Run zodiacal releasing from Spirit. ZR from Spirit produces a timeline of vocational eras and chapters across the life. Astrolium runs this in 1 click after computing Spirit.
Quick reading template. Spirit in the 10th house: a vocational arc oriented around public role and recognition. Spirit in the 5th: creative work, teaching children, the arts. Spirit in the 12th: behind-the-scenes work, monastic or research vocations, the hidden craft. Traditional house topics scale to Spirit; the lot foregrounds them across the 12 houses as the locus of chosen effort.
Spirit in zodiacal releasing
The most consequential working use of Spirit is as the starting point for zodiacal releasing, the hellenistic technique that releases nested time periods from the lot and produces the Spirit ribbon across the life.
ZR from Spirit reads vocational timing. The L1 periods (8 to 30 years long) are vocational eras, the chapters of working life. The L2 sub-periods (months to years) are sub-chapters within. Peak Spirit periods (when an L1 or L2 sign is angular relative to Spirit) tend to be years of public action, output, and recognition: the year the book gets written, the year the company launches, the year the work becomes visible.
The Spirit ribbon does not move in lockstep with the Fortune ribbon. A peak Spirit period during a quiet Fortune period is the year of major output that does not yet pay (the book finished but not sold). Reading both ribbons together lets you separate vocational momentum from material consequence. Astrolium runs ZR from Spirit in 1 click after Spirit is computed, with both ribbons displayed side by side in the predictive timing feature.
Spirit and the vocational question
Clients ask vocational questions in patterns: "should I make this move?", "is now the year for the book?", "what kind of work am I structurally suited to?", "when will the career arc shift?" Most of these are Spirit questions, not Fortune questions.
The basic read:
- Spirit's sign and house describe the kind of vocation the chart is structured for, that is, the character of the work.
- The lord of Spirit's placement describes where the vocation is supported or stressed, that is, the conditions under which the work happens.
- Aspects to Spirit and to its lord describe the texture of the vocational arc: supported, contested, isolated, collaborative.
- ZR from Spirit dates the eras and chapters of the working life. When the major pivots happen.
A working procedure: compute Spirit, identify its lord, run ZR from Spirit to find the current L1 and L2, cross-reference with the year's profections and the nearest saturn return. The convergences are the high-density vocational windows. For the doctrinal foundation of Spirit and Fortune in the ancient sources, read the arabic parts guide.
After the calculator
Compute Spirit, then run its partner lot. The part of fortune calculator gives you the body-side counterpart: what happens, the material life, the contingent circumstance. Together Spirit and Fortune form the spine of hermetic predictive work.
For the full 7-lot panel (Fortune, Spirit, Eros, Necessity, Courage, Victory, Nemesis), the predictive timing feature computes all 7 with sect-aware formulas and tracks transits to each across 75 years of timeline. The $29 per month Pro tier exposes all 7 lots pre-computed for every chart on your client roster.
For the interpretive context, read the arabic parts guide. For the broader doctrinal setting, see the hellenistic astrology guide. For the predictive technique that releases from Spirit and Fortune in parallel, read the zodiacal releasing guide.
