How common the sign is overall
Each count is out of the 151 years examined. They add up to more than 151 because July 23 is a cusp date: in some years the Sun changes sign during the day, so that year counts for both signs.
Bars start at zero.Each bar is the share of the 151 years in which the Sun was in that decan (a ten-degree third of a sign) at some point of July 23. The years overlap: in some years the Sun is in two decans on this date.
An even split of the 12 signsBars start at zero.Over all simulated births, on any date of the year, not only July 23. Each entry also gives the years, out of 151, in which the Sun was in that sign at some point of July 23. Share of 2,000,000 simulated births (1950–2024), tropical zodiac.

The Moon moves no more than about 16 degrees a day, so within one date it is in one sign or, when it crosses a boundary, two. Which signs depends on the year: across 1900–2050 the Moon was in each sign on July 23 in the number of years below.

The Sun in Leo is in domicile, the planet's own home, and the tradition lists no other planet's rulership here. Leo is a masculine, fixed fire sign; the Sun is a masculine, day-team planet, so sect, gender and sign agree.
Leo is the fifth sign of the zodiac, a fixed fire sign with positive polarity, and the only sign the Sun governs in traditional astrology.

Cancer begins at the June solstice, when the Sun reaches its northernmost point. The Sun in Cancer sits in a feminine, cardinal water sign.
The Sun in Cancer places the Sun in a cardinal water sign with negative polarity, the sign the Moon governs in traditional astrology. Modern psychological astrology reads the Sun as identity and cardinal water as identity formed by caring, protecting and remembering.

The first decan of Leo covers 0° to 10° of the sign. Firmicus Maternus gives its face ruler, in the Chaldean order, as Saturn, while Leo's domicile lord, the planet that rules the sign, is the Sun. Chaldean order runs through the seven visible planets from slowest to fastest, and this decan falls to the slowest, Saturn. Medieval authors rank a face as the lowest of the five dignities. Saturn is in detriment in Leo, a concept the tradition names explicitly only late, so the face ruler has weak standing in the sign itself. Saturn is also a malefic, a planet the tradition treats as difficult in nature. It shares the Sun's day team under sect, the tradition's sorting of planets into day and night teams. Leo is a masculine, fixed fire sign. Later practice reads the face after the major dignities, not instead of them.
A note on “detriment”: the early Hellenistic texts note a planet opposite its own sign without naming it. The term is defined only in late and medieval sources, and scholars disagree on whether the idea was implicit earlier.

Reviewer's notes
Face ruler matches Firmicus Mathesis II.4 and the project's Chaldean decan table. Original claim that Hellenistic astrologers rank a face lowest was wrong (Firmicus equates a planet in its own decan with domicile; the ranking is medieval), so the text now attributes by author. Brennan's coverage of decans was not independently opened; existence of the 2017 book confirmed. Added a note that detriment is a late-named concept.

The first decan of Leo covers 0°–10° of the sign, and a decan is a ten-degree third of a sign. In the modern triplicity convention the first decan keeps the sign's own character, so this one is Leo by Leo. That makes it fixed fire, with the Sun as its governing planet. Modern psychological astrology reads this as the most characteristic expression of the sign, with warmth, pride and a drive for visible self-expression. Modern readings describe the tension as having no second sign to soften it, so need for acknowledgment appears unmixed. The Chaldean scheme, used by Hellenistic astrologers for the face, assigns this decan to Saturn instead, a planet associated with restraint. The two conventions differ because they use different rules.

Verified against the reference data: Leo 1 is Leo by Leo in the same-element scheme; the Chaldean face is Saturn. Sources: Brennan removed because a review states his book does not cover decans; Arroyo kept on the strength of a library record listing decans, so the modern reading is attributed to modern readings in general, not to his text.

The third decan of Cancer covers 20° to 30° of the sign. A decan is a ten-degree third of a sign. Firmicus Maternus gives its face ruler, the planet of that slice in the Chaldean order, as the Moon. The Moon is also Cancer's domicile lord, the planet that rules the sign. Chaldean order deals out the seven visible planets from slowest to fastest, Saturn, Jupiter, Mars, Sun, Venus, Mercury, Moon, three decans to each sign. Firmicus holds that a planet in its own decan acts as if in its own domicile. Medieval authors rank the face as the weakest of the five dignities. Here the face and sign rulers are the same planet, so a placement in this decan has the Moon in both roles. Cancer is a feminine, cardinal water sign. Later practice reads it as a lesser factor, after the planet's major dignities.

The third decan of Cancer covers 20°–30° of the sign. A decan is a ten-degree third of a sign. The modern convention, also used in Vedic drekkana, assigns each decan a second sign of the same element: here Pisces, the third water sign, after Cancer and Scorpio. According to Astrodienst, Alan Leo introduced it to Western astrology in the 20th century. Modern psychological astrology reads this as Cancer's protective, memory-bound character shaded by Pisces' permeability and imagination. Modern readings associate the decan with heightened sensitivity and a pull toward the intangible. The tension described is porous boundaries combined with a wish for shelter. The older Chaldean order, used by Hellenistic astrologers for their faces, gives this decan to the Moon instead. The two schemes assign different planets and signs, so decan readings depend on which one is used.

Reviewer's notes
Verified against the reference data: Cancer 3 spans 20°-30°; same-element sub-sign is Pisces (Cancer, Scorpio, Pisces); the Chaldean face of Cancer 3 is the Moon. The text says plainly that the same-element scheme is a modern convention, also in Vedic drekkana, and credits Alan Leo for its entry into Western astrology as Astrodienst reports (one source). Sources: Brennan removed because a review states his book does not cover decans; Arroyo kept on the strength of a library record listing decans, so the modern reading is attributed to modern readings in general, not to his text.
