Your decan
The first decan of Leo is the sign with nothing cutting it — double Sun, pure performance, pure pride. You are the most radiant, most generous, and most nakedly hungry for recognition of all the Leos. When the room lights up, you're not near the source — you are the source.
What sets your third apart
With the Sun ruling both the sign and this decan, there's no second planet to add complexity, detachment, or a reason to share the spotlight. It makes you the most genuinely warm and magnanimous Leo — and the most likely to collapse into sulking when the applause stops, because your entire internal weather depends on whether people are looking.
Your gift
Presence so natural and warm it fills a room before you've said a word.
Your watch-out
You've built your self-worth on the audience; when they look away, you don't know who you are.
The exact degrees, and who rules them
A decan is a third of a sign: ten degrees of zodiac, not a mood. Yours is Leo 0°00′ to 9°59′ — the first ten degrees the Sun crosses on its way through Leo, roughly Jul 23 – Aug 1 in most years. Sun-sign dates shift by up to a day between years because the tropical year is not a whole number of days, so if you were born within about 24 hours of either end, run the actual chart rather than trusting a date table.
| Tradition | Ruler | What it governs |
|---|---|---|
| Sign ruler (all three decans) | Sun | The baseline Leo everyone shares |
| Chaldean face | Saturn | structure, limits and time |
| Triplicity decanate | Sun | identity and vitality |
The two systems disagree, which is normal and worth knowing: the Chaldean faces run the seven classical planets in speed order straight through all 36 decans without regard to sign boundaries, while the triplicity decanates give the first third of every sign to its own ruler and then step through the other signs of the same element. Most popular astrology quotes the triplicity ruler (Sun) without saying so; the older Leo face here is Saturn.
Read either way, the point is the same: visibility — this third wants the thing it does to be recognisably its own.
How it actually shows up
The decan is a modifier, not a second sign. It shifts emphasis inside Leo rather than replacing it — so everything true of Leo is still true of you, with identity and vitality turned up. Three places people notice it:
- Under pressure. A Leo sun typically performs the hurt until it is noticed. In this third that reaction takes its colour from Sun — identity and vitality is what the reaction ends up being about.
- In how you start things. The first decan sits at the front of the sign, where its qualities are least diluted and most raw.
- Next to the other two. Compare it directly: the second decan (Aug 2 – Aug 12) runs on Jupiter, and the third decan (Aug 13 – Aug 22) runs on Mars. Same sign, three noticeably different settings.
What it is not: a personality test, and not something to weigh against your Moon or rising, both of which say considerably more about you than a third of your sun sign does. The big three is where to look next.
Your decan is a hint. Your chart is the answer.
The decan refines your sun sign — but your moon, rising and every planet are where the real story lives. Run your full birth chart, free.
Degree ranges are exact by definition (each decan is ten degrees of zodiac); the calendar dates shift by up to a day between years. Rulerships are the classical Chaldean face and triplicity decanate assignments, both stated above.
