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 28 in the number of years below.
Bars start at zero.Counts overlap: a year in which the Moon changes sign during the date counts for both signs. UTC dates.

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.

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.

Reviewer's notes
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.
