Jupiter takes about one year to go through each sign.
It has an expansive energy to it. What ever it touches grows. This means if it touches something good, that good grows. But, if it touches something bad, that bad grows.
In your birth chart it represents your pool of life experiences. When you step out of your comfort zone and expereince something new, you expand your world view. Jupiter can be foreign culture, language, food, or lands. It’s things that take you so far out of the realm of what you are used to in ways that can help your perspectives grow in unthinkable ways.
Where Mercury represents your lower mind, Jupiter is your higher mind. It’s when you take all the information that Mercury collected and you synthesize it. You create your own philosophies and theories about the world.
Jupiter energy can also be found in higher education. The life of a scholar is the life of a Jupiter dominated person. Universities are the home to tons of students who come to learn and deepen their understanding in their field of choice. They take knowledge beyond the bare necessities into the realm of deep comprehension. Professors conducting research and teaching theirs discovers is also Jupiter. Jupiter not only wants to understand, but it wants to share that understanding with others.
It’s an adventurous planet. It represents long distance travel. It’s any trip that’ll take more than a day to do. It gives you the desire to explore things out side of your own daily reach. It often requires freedom for this very reason. With out freedom, Jupiter would be too tied down to truly grow and bloom.
Jupiter is also notorious for its association with luck, though I am typically weary of calling it luck itself. Whatever energy you invest in Jupiter goes a really long way, and luckily enough Jupiter is incredible intuitive. If you listen to the pull, it’ll take you right where you need to go. You’ll find that you really don’t have to put in much work when you happen to always be in the right place at the right time. It also tends to have our back. Even if we don’t go to the right place, usually the wrong place wont be that bad itself.
Where Jupiter is it’s easier to get a bird’s eye view of things. It asks you to broaden your perspectives, and when you zoom out past all the little mundane things, it’s often easy to see things will be all right. It’s a happy-go-lucky planet, not getting caught up in the hows, but rather following the whys.

Personally, my Jupiter is in Sagittarius and the Sixth house. I tend to have an easy time with routine stuff, not having to put in a lot of effort. I also am really good at looking at the little details and recognizing how they create the bigger picture.
