What is a transit? The sky right now, and your own chart
If your natal chart is the terrain, a transit is the weather moving over it. A plain look at how the planets overhead relate to you right now, with none of the warnings.

You have probably heard someone say “careful, Mercury’s retrograde.” What a transit actually is, though, rarely gets explained. That is the one thing I want to write about today, carefully.
The map that doesn’t move, and the moving sky
Your natal chart is a single map, a copy of the sky at the moment you were born. It never changes for the rest of your life. The planets up in the sky, on the other hand, are still moving, right now, this second.
A transit is one of those moving planets, and looking at transits means looking at where the sky as it is now sits against the map you were born with. The natal chart is terrain that stays put; the transits are the seasons and weather passing over it. The same patch of land asks something different of you on a clear day than it does in a storm.
What it can tell you
There are stretches when the moving Jupiter comes to sit on top of your natal Sun. Astrology tends to read that as a time when the view opens up and things move more easily. The opposite happens too: when the moving Saturn forms a heavy angle, that reads as a time to stop, set your feet, and shore up the ground under you.
The important part is that a transit is not a prediction of when something will happen. Knowing what kind of wind is blowing before it arrives gives you a little room in how you take the same event. If you know rain is coming, you can leave the house with an umbrella. That is about the right distance to keep with it.
On Mercury retrograde
The most famous transit of all is probably Mercury retrograde. People tie it to crossed wires and scrambled plans, but the thing underneath it is simpler: from where we stand on Earth, Mercury appears to move backward for a while.
This, too, is not knowledge for bracing yourself. Treating it as “let me add one more check than usual for now” is about as much weight as it needs to carry. You don’t have to give anything up because of a retrograde.
Seeing your transits in Hoshidou
In Hoshidou you can lay the planets of the sky as it is now over your own natal chart and see where they fall. Start by just watching where the moving Sun or Moon is passing through your chart. The wind blowing over you right now starts to come into view.
This overlay shows up in Hoshidou as the triple wheel. It stacks three concentric rings — natal, progressed, and transit — so you can see, on one screen, how the sky now is working against the map you were born with.
