Why not just draw the transiting planets’ lines on the map?

Because they sweep. A line’s position depends on sidereal time, so a transit line crosses every longitude on Earth once a day. Asking where Jupiter’s line is today gets the answer "everywhere, in turn". Desktop software plots them because its users are electing a precise moment, not choosing where to spend a season.

So what is actually moving?

Nothing on the map. Your natal lines are fixed for life. What changes is which natal planet is under transit — and while it is, every line belonging to that planet is carrying a charge. The map stays still; the meaning moves.

Which transits count here?

Mars and outward. The Moon, Sun, Mercury and Venus aspect everything within days, which produces a permanent hum rather than a window. They are weather. This page is about seasons.

What is the difference between a season and a passage?

What is doing the pressing. Saturn, Uranus, Neptune and Pluto move slowly enough to reshape something over months — a season. Mars and Jupiter cross in weeks — a passage. Both are usable; they are usable for different things.

Does a charged line mean I should go there?

It means that line is live rather than dormant. Whether you want what it carries is a separate question — a charged Saturn line is a real opportunity to build something and a poor choice for a holiday. Read the line first, then the timing.

Why does nothing open in my next twelve months?

Slow transits arrive on their own schedule and some years genuinely are quiet. That is worth knowing: an empty year is a reason not to force a move, and the timeline shows you where the next opening is.

What Is Cyclocartography?

Astrocartography draws the places where each planet in your birth chart was angular — rising, setting, culminating, or at the bottom of the sky. Those lines are fixed. They were set the moment you were born and they will be in the same places when you are eighty. Cyclocartography adds the one thing a static map cannot carry: time. Not by moving the lines, but by asking which of them is currently under pressure. That question has an answer measured in weeks and months, which is the scale a person deciding where to spend the next year actually needs.

Why Drawing Transit Lines on a Map Does Not Work

The intuitive build is to compute where the transiting planets are angular today and draw those lines instead. It produces a picture, and the picture is useless. A line's position depends on sidereal time, which advances a full turn every day. So a transit line does not sit somewhere — it sweeps. Over twenty-four hours, transiting Jupiter's Midheaven line crosses every longitude on Earth. Ask where it is and the honest answer is "everywhere, in turn". Choosing a city because a transit line passes through it is choosing a city because the Earth rotates. Professional desktop software does plot these, and correctly so, because its users are doing something different: electing a precise moment for a precise act. If you want to know where on Earth to sign a contract at 14:32 next Tuesday, a transit map answers that. If you want to know where to live next year, it cannot.

Your Lines Do Not Move — Their Charge Does

Here is the pivot that makes timing work. Your natal Venus lines are wherever they are, permanently. What is not permanent is Venus itself being quiet. When transiting Saturn comes to conjunct your natal Venus, that placement is under pressure for months — and everything derived from it comes under the same pressure, including all four of its lines on the map. Nothing has moved. The Venus MC line runs through the same longitude it always has. But for the length of that transit, standing on it means something it did not mean last year: the part of you that line represents is being worked on. That is what this page computes. For every natal planet, it scans the year ahead for transits from Mars outward and reports the stretches when each one is charged.

Reading Your Heat Timeline

One lane per natal planet, running left to right across the next twelve months. A bar means that planet is under transit, so its lines are live. Thicker bars are seasons: Saturn, Uranus, Neptune or Pluto, slow enough to reshape something over months. Thinner bars are passages: Mars or Jupiter, crossing in weeks. Both are usable, for different things. The faster bodies are excluded on purpose. The Moon aspects every point in your chart within a couple of days; the Sun, Mercury and Venus take a few weeks each. Including them would hold every lane permanently warm and hide the windows underneath. They are weather. This page is about seasons. An empty year is a real result and worth having. It means no slow transit is due, which is a reason not to force a decision rather than a failure of the tool.

Timing a Move or a Trip

Two questions, asked in order. Where, then when. First read the line itself. A Jupiter line and a Saturn line offer entirely different things, and a charged line you do not want is still a line you do not want. Timing does not change what a placement means; it changes whether that meaning is currently loud. Then match the tempo to the commitment. A season — months of a slow body working on the placement — is the window worth relocating inside. A passage of a few weeks is a trip, a visit, a stretch of concentrated work. Signing a lease for a three-week Mars passage is a category error. And the peak is not a deadline. The strongest day is where the transit perfects, but the window is the whole stretch. Arriving early and staying through it is closer to how these things are usually lived.
