Your decan

The third decan of Leo is the Sun's warmth lit by Mars-Aries fire. You're the most action-driven, competitive, and openly bold of the Leos — less the lounging king, more the one who charges into the arena to earn the crown.

What sets your third apart

Mars, by way of Aries, adds drive and impatience to Leo's natural pride. It makes you braver and more direct than the other Leo decans, but also quicker to anger and more likely to turn a need for admiration into a need to win. Your warmth runs hot both directions.

Your gift

Courage to match the confidence — you don't just want the spotlight, you go take it.

Your watch-out

Pride plus a short fuse; you defend your ego like a battlefield no one was attacking.

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 20°00′ to 29°59′ — the third ten degrees the Sun crosses on its way through Leo, roughly Aug 13 – Aug 22 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.

Both surviving decan systems agree here, which is not the usual case — the Chaldean faces and the triplicity decanates both hand this stretch to Mars. When they agree, the sub-flavour is about as well attested as decan theory gets.

Read either way, the point is the same: urgency — this third of the sign starts sooner and argues quicker than the other two.

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 drive and confrontation turned up. Three places people notice it:

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.
