Leo runs on the Sun. Big days line up with solar transits and 5th-house activations—visibility, creativity, attention.
What's in Leo
Jupiter is in Leo right now.
Every planet's sign todayLeo season, to the day
Leo season next runs 23 July to 23 August. Those are real crossings, computed from the Swiss Ephemeris—the almanac's “July 23 – August 22” is a rounded average, and it is a day out most years.
What touches Leo in September 2026
Every movement this month that stands in a whole-sign relation to Leo, with the solar house it falls in. Sky-to-sky aspects are left out: they have no sign of their own, so they stand in no relation to yours.
- Venus enters Scorpio on the 10th, square your sign—your 4th house.
- Mercury enters Libra on the 11th, sextile your sign—your 3rd house.
- Uranus stations retrograde in Gemini on the 11th, sextile your sign—your 11th house.
- The full moon falls in Aries on the 26th, trine your sign—your 9th house.
- Mars enters Leo on the 28th, in your own sign—your 1st house.
- Mercury enters Scorpio on the 30th, square your sign—your 4th house.
What a sign gives the engine—and what it doesn't
Sun rules Leo, and that matters to the scoring in one specific way—not the way most sun-sign writing implies. Nothing gives Sun extra weight because you are Leo; the scoring never reads your Sun sign at all. What it does read is the transiting planet’s own condition: a Sun moving through Leo is in domicile, and our astrology engine counts that contact for more than the same aspect from a Sun with no dignity.
In Leo, the Sun is in domicile; Saturn is in detriment, and no planet falls here. Those conditions are the whole of what a sign does to a transiting body in our rulebook—the same dignity table the scoring reads, which is why a transit from a planet in its own sign counts for more than the identical angle from one with nothing here.
Right now Leo’s ruler, the Sun, is in Virgo, holding no dignity either way there.
The other thing a sign gives our astrology engine is geometry. Every transit stands in a whole-sign relation to Leo—conjunct, sextile, square, trine or opposite—and that relation is fixed by the sign alone, so it is computable without knowing anything else about you. The dated lines above are exactly that, and exactly its limit.
Leo is a fire sign, with Aries and Sagittarius. That is a fact about the sign and not about the scoring: our rulebook has no element term in it at all. The dated list above is computed for Leo alone, and it comes out different for Aries and Sagittarius—same element, different geometry.
“Leo, today the universe is on your side.”
Right now the sky holds what it holds—and whether any of it is “on your side” depends on where it lands in your chart, not on your being Leo. Here is what is actually in the sign, and what touches it this month.
Kalendom is the precise and honest horoscope: it reads your natal chart against the real sky and turns months like this into your exact dates.
What the chart doesn't tell you
Sun-sign astrology is the entry point—it's also the least specific bit. Two Leo suns born minutes apart in the same city can have wildly different days because their Ascendants (the cusp of the 1st house) sit at different degrees. House placement is where the mainstream horoscope stops and we keep going.
That's why the calculator asks for your birth time. With a real Ascendant, the Kalendom engine maps every transit to a specific house, so "Mars in your 5th" means something concrete for your life rather than a generic Leo blurb.
Your sign is a personality, not a calendar
Everything above describes what Leo tends to feel like. None of it can tell you when—two people born three weeks apart are both Leo and share almost none of the same strong days. Timing comes from a whole chart meeting a moving sky, so here is one being scored against three real months of it.
We build your natal chart with the Swiss Ephemeris, place it in Placidus houses, then score each day by how the transiting planets aspect your chart—per life area, 0 to 100, with the exact reason. It is astronomy applied to your birth chart, not numerology.
The rulebook encodes that tradition whole—four centuries of transit doctrine, written down as rules you can read, not a model that guessed. Read the methodology.
