Free Lot of Spirit Calculator

The Lot of Spirit is a calculated zodiacal point based on the Ascendant, Sun, and Moon. Ancient astrologers associated it with the mind, intention, deliberate action, employment, and rank. Its sign, house, and ruler describe how those topics are expressed in the chart.

Paulus Alexandrinus calls Spirit the lord of “soul, temper, mindfulness, and every power,” and says that it contributes to what a person does. Vettius Valens tells the reader to examine the Lot, its ruler, and the ruler’s place when judging action and employment.[1][2]

Modern astrologers often use life purpose as shorthand for this group of topics. That phrase can be useful if it stays modest. The Lot supplies symbolic testimony about intention and action. It does not identify one required career or guarantee a calling.

First determine whether the chart is diurnal or nocturnal. A day chart has the Sun above the local horizon. A night chart has the Sun below it. Paulus and Valens reverse the arc between the Sun and Moon according to this distinction, known as sect.[1][2]

This calculator follows that sect-sensitive method. All three positions are converted to absolute longitude from 0 to 360 degrees. The selected arc is added to the Ascendant, then the result is normalized into the same range.

Why calculators can disagree on night charts

Of the 326 surviving Greek horoscopes, 90 compute Fortune and 33 compute Daimon. Spirit is the second most attested lot in the documentary record. Among the charts that compute Fortune, only two depart from the sect-reversed rule. One of those is fragmentary and uncertain; the other is P. Lond. I 130, a horoscope cast for 31 March 81 CE. The surviving charts themselves reversed the formula by sect almost without exception.[7][9]

Ptolemy uses one Fortune formula by day and night. He writes, “Take as the Lot of Fortune always the amount of the number of degrees, both by night and by day, which is the distance from the sun to the moon.” He recognizes Fortune alone among the lots. Ibn Ezra later applies an unreversed rule to Spirit as well.[3][7][12]

In the fourth-century Mathesis, the transmitted directions for Daemon repeat the directions for Fortune and collapse the two calculations. Bram attributes this to confusion in Firmicus or his manuscript.[6]

Current calculators use different conventions. If two results disagree for a night birth, check the displayed formula first. Birth time, horizon handling, rounding, zodiac choice, and house system can cause other differences. The zodiacal degree does not change with the house system, although its house placement can.

Use an Ascendant at 10° Aries, a Sun at 20° Taurus, and a Moon at 5° Gemini. Their absolute longitudes are 10°, 50°, and 65°.

Sect reversed night formula: 10 + 65 − 50 = 25°. The Lot of Spirit is at 25° Aries.

Unreversed formula: 10 + 50 − 65 = −5°. After adding 360°, the result is 355°, or 25° Pisces.

The same birth data produces a different sign because the second calculation keeps the day arc at night. This is the first setting to compare when another calculator gives a different result.

Keeping Ptolemy’s unreversed Fortune formula beside sect-reversed Spirit collapses the pair in every night chart. Ptolemy’s Fortune is Ascendant + Moon − Sun in every chart, the same expression as the night Spirit formula in the table above. Fortune also falls at 25° Aries in this example, the same longitude as Spirit. The sect-reversed reading keeps the two lots as a reciprocal pair.[7]

The Sun and Moon longitudes come from the JPL DE440s planetary ephemeris through ANISE. The Ascendant is calculated from the birth time, location coordinates, and ecliptic obliquity. The calculator determines sect from the Sun’s position above or below the local horizon at the recorded birth moment.

The final longitude and zodiac sign are independent of the house system. This page reports whole-sign houses, where each sign forms one house beginning with the rising sign. A quadrant system such as Placidus can assign the same degree to a neighboring house.

Births close to sunrise or sunset require extra care. A small time error can move the Sun across the horizon, change the sect, and reverse the formula. An approximate time may be ambiguous in that window. The birth time rectification tool can help you examine the uncertainty.

Spirit and the Lot of Fortune are a reciprocal pair. Fortune describes bodily and circumstantial conditions. Spirit describes thought, intention, and deliberate action within those conditions. Ancient astrologers often read them together rather than treating either point as sufficient on its own.[1][2]

Because the two formulas reverse the same Sun and Moon arc, the lots sit at equal distances from the Ascendant in opposite directions. At a new moon they coincide near the Ascendant. At a full moon they coincide near the Descendant. When the luminaries are square, the lots oppose one another.[2][4][10][11]

One traditional manuscript siglum for Daimon shows a small circle or globe with two descending strokes. Avelar and Ribeiro reproduce this form in their account of the lots. Glyphs can vary by source and typeface.[9][11]

Horoscopes from Roman Egypt preserve the Lot of Daimon as a calculation used in practice. In his commentary on the deluxe horoscope P.Oxy. 4277, Alexander Jones writes, “The Lot of Daimon should be as many degrees ahead of the ascendant as the Lot of Fortune is behind it.” P.Oxy. 4277, 4279, 4284, and 4295 preserve Daimon.[4]

A chart preserved from Valens, No. L 106 in Greek Horoscopes, places Daimon in Cancer. Its reading states, “the Daimon in Cancer. Then in opposition to the Daimon, which forecasts the intellectual and the spiritual, was Saturn.” The astrologer uses Spirit as testimony about the mind.[5]

The named nativity of Pamprepios of Panopolis, dated 29 September 440 CE and preserved in Rhetorius, computes both Fortune and Daimon. Its commentary directs the reader to the lord of the Ascendant and the Lot of Daimon.[5][7] The Lot of Spirit survives in working documents, from Oxyrhynchus papyri to named late-antique nativities, rather than being a modern reconstruction.

The techniques built on Spirit returned to wider use through the recent revival of Hellenistic astrology. Brennan places Project Hindsight and Robert Schmidt’s translations at the center of that revival. The 1993 Paulus translation cited on this page was the project’s first published Hellenistic text. Zodiacal releasing from Spirit is another revived technique used by contemporary practitioners.[8]

Valens gives the ruler of Daimon special weight. He says its best position is at the Lot of Fortune or the tenth place from Fortune, where he counts the nativity illustrious and distinguished. In its proper place or at another angle, he judges it as distinguished and vigorous as circumstances allow.[2]

Obert treats the ruler as perhaps the most important single factor in evaluating the Lot. He judges the ruler’s location and condition, including dignity or debility. Its aspect to the Lot shows how much support the Lot receives from its ruler. Angular placements tend to be strong, prominent, visible, and active. Cadent placements tend to be weakest, with action turned inward.[10]

Taken together, a strongly placed Spirit with a well-supported ruler tends toward visible, self-directed activity. A weakly placed Spirit can describe effort that runs quieter or routes through others. This is a tendency rather than a verdict. The substitution doctrine below lets Fortune carry Spirit’s topics when Spirit is poorly situated, and Spirit can do the same for Fortune. A weak placement therefore leaves other routes open.

The Greek name is klēros Daimonos, usually translated as Lot of Daimon or Lot of Spirit. The ancient Greek word daimōn had a wider range than the later English word demon. Depending on the context, it could refer to a divine power, an allotter, a guardian, or a personal spirit. Scholars often connect the word with allotting or dividing, which suits a klēros, an allotted share.[9]

Greenbaum traces two enduring ideas to Plato: daimons mediate between gods and humans, and each person has a personal daimon that guides them through life. For astrologers, this personal daimon could be discerned in the chart.[9]

In the Myth of Er at the end of Plato’s Republic, souls choose the daimon that will accompany their next life. The order of choice is determined by drawing lots. This pairing of a guardian with the drawing of lots supplies the conceptual background for a klēros of the Daimon. The modern phrase life purpose echoes this older idea of a guiding spirit allotted at birth.[9]

Part of Spirit and Lot of the Sun are common alternate English names. Translation history produced other names, but several neighboring lots have similar titles. This page uses Spirit and Daimon because those labels identify the calculation without merging it with a separate lot.[11]

Ruler and place. Valens calculates Daimon, then immediately directs the reader to its ruler and the place occupied by that ruler. This is why the result gives the ruler more weight than a sign description alone.[2]

Employment and rank. In Book IV, Valens begins a timing sequence from Daimon when investigating employment or rank. He begins from Fortune for bodily matters. Chris Brennan reports using the same distinction for career and life direction in modern practice. Firmicus calls Daemon “the essence of the soul” and adds, “from this place we find professions.”[2][6][8]

Other Hermetic lots. Paulus measures the Lot of Eros from Spirit to Venus and the Lot of Victory from Spirit to Jupiter. The Fortune and Spirit pair also supplies the starting points for the Lot of Basis.[1][2]

Substitution. Valens says that Spirit can distribute both bodily and active topics when Fortune or its ruler is poorly situated. Fortune can carry both sets of topics when Spirit or its ruler is poorly situated.[2]

Ptolemy’s alternative. In the Tetrabiblos, Ptolemy assigns bodily events to the Ascendant and property to Fortune. He assigns the soul to the Moon, dignity to the Sun, and actions to the Midheaven. Spirit is absent from this system.[3]

Timing and life. Valens titles Book IX, chapter 2, “The Lot of Fortune and Daimon. Their Relationship to the Topics of Propitious and Impropitious Times and of Life.” He treats the pair as controlling places in judgments of time and in his length of life procedures.[2]

Zodiacal releasing can begin from the sign containing Spirit when the subject is action, employment, or reputation. Each sign receives a fixed period. Capricorn is the exception to Saturn’s ordinary minor years in this technique, receiving 27 years while Aquarius receives 30.[8]

When the release starts from Spirit, peak periods occur as the active sign reaches Fortune itself or the fourth, seventh, or tenth sign from Fortune. A peak period indicates heightened activity or visibility within this method. It does not guarantee a particular event.[8]

The zodiacal releasing calculator calculates the full sequence, including subperiods and loosing of the bond dates.
