Planets in Signs
Jupiter governs growth, luck and belief, and Leo is a fire sign in fixed mode. Here is what the placement does, its shadow, and the real dates Jupiter is in Leo.

Jupiter spends about a year in each sign, so anybody born in the same window shares the sign with you. What makes it yours is the house it falls in and the aspects it makes to the rest of your chart. This page is about the sign. The other half needs your birth time.
Before the sign, the planet. Jupiter rules growth, luck and belief. The question it keeps asking is where do I expand. Wherever Jupiter sits in a chart is the department that question gets answered in.
Leo is a fire sign, which describes what it cares about, and fixed, which describes how it goes about things. Fire acts first and thinks about it afterwards. Fixed signs hold on.
Jupiter is neither dignified nor debilitated in Leo. It neither rules the sign, nor is exalted in it, nor is in detriment or fall. In traditional terms that is called peregrine, and it means the planet is working without any particular advantage or handicap: it simply takes the character of the sign it is in. Most placements in most charts are like this, which is worth saying because pages that describe every placement as either blessed or cursed are not describing astrology.
Where life keeps handing you more than you asked for, run through Leo. In practice that tends to look like warm, generous and proud, applied specifically to growth, luck and belief, rather than to everything you do.
Leo's keyword is "I will", and the version of that which belongs to Jupiter is narrower than the sign description you will have read elsewhere. Somebody with Jupiter in Leo and very little else in the sign is not a Leo person. They are a person who handles growth, luck and belief the way Leo does.
More of whatever Leo counts as good, which here is something that moves, and the freedom to change direction without a conversation about it. Jupiter does not moderate; it enlarges whatever it touches, including the sign's blind spots.
And what it finds hard: knowing when enough has arrived. Needs the room to notice, enlarged, which is a specific kind of trouble.
Jupiter returns to Leo on a regular cycle. These are the real dates, computed from an ephemeris rather than copied, so you can check your own birth date against them.

This is the part most planet-in-sign pages leave out, and it is why two people with the same placement can recognise almost nothing of each other in it. Jupiter in Leo in the tenth house is a public thing. The same placement in the twelfth is nearly invisible, including to the person who has it.
Which house it lands in depends on your rising sign, which depends on your birth time. The rising sign pages set out the whole structure, and the table there shows which house Leo occupies for each of the twelve.
| Planet | Jupiter |
| Sign | Leo |
| Element and mode | Fire, Fixed |
| Sign ruled by | the Sun |
| Essential dignity | None. Neither dignified nor debilitated here |
| Needs a birth time | Rarely for the sign, always for the house |
The same planet in the signs either side is the sharpest comparison available: Jupiter in Cancer and Jupiter in Virgo. And the leo decans narrow a thirty-degree sign down to ten, which is three times more specific than the placement on its own.
Jupiter governs growth, luck and belief, so in Leo it handles that department in a Leo way: warm, generous and proud.
It is neutral, or peregrine: Jupiter neither rules nor is exalted in Leo, and is neither in detriment nor fall. It simply takes on the character of the sign. Most placements are like this.
Not for the sign itself, which Jupiter holds for a year in each sign. You do need one for the house it sits in, and the house is half the meaning.
Overcommitting, then resenting the commitment, shaped by Leo's tendency to needs the room to notice.
