Transits: the moving sky

This is an introduction to ZodiacFolk’s reflective approach to modern Western astrology, which measures the zodiac from the March equinox (the “tropical” zodiac). Other traditions, including predictive ones, work differently.

Your birth chart is a snapshot: where every planet was the moment you arrived. But the planets didn’t stop. They’ve been moving ever since, and a transit is simply the name for where a planet is right now compared with your snapshot.

Think of the birth chart as a map of a town, and transits as the weather moving over it.

How it works

Each day, astrologers look at the planets overhead and ask: which part of your chart is a moving planet touching? “Transiting Mars meets your natal Moon” (natal just means from your birth chart) is a technical way of saying the Mars of today is sitting on the spot where your Moon was at birth. Put in plain words: your energy and action are meeting what helps you feel at ease.

Speed matters

The faster the planet, the shorter its stay in a sign. These are rough times spent in a sign, and retrograde stretches can make a stay longer.

• Moon: changes signs about every two to three days. A transit that comes and goes in hours.
• Sun: about a month per sign.
• Mercury, Venus, Mars: a few weeks to a couple of months per sign, depending on the planet.
• Jupiter: about a year per sign.
• Saturn: about two and a half years.
• Uranus, Neptune, Pluto: many years each, so their transits are long chapters.

A quick rule: Moon transits are the mood of the day, the personal planets are the theme of the week or month, and outer-planet transits are the long story of a season of life.

How long a transit lasts is a separate question from how long a planet stays in a sign. A transit to a spot in your chart lasts while the moving planet is within the allowed wiggle room (the orb) of that spot, and a planet that goes retrograde can return to the same spot more than once.

What does retrograde mean?

Sometimes a planet appears to move backward across the sky, as seen from Earth. This is an optical effect, like a car you’re passing on the highway seeming to drift back. Astrologers call it retrograde and tie it to revisiting things rather than starting them. Mercury goes retrograde roughly three or four times a year, for about three weeks each time. It doesn’t mean something is about to go wrong. It’s an invitation to double-check your email before you send it.

What a transit can and can’t tell you

A transit describes a theme: “this is a good stretch for thinking carefully” or “this angle tends to bring tension to routines.” It doesn’t tell you what will happen. Two people with the same transit can have completely different days, because their lives and charts are different. Use transits as a prompt for reflection: what part of my life does this question touch?

Why “today’s sky” feels personal

Everyone shares the same sky at the same moment. What makes a reading personal is where those planets land in your chart. That’s what a good daily reading does: it takes the shared sky and shows which part is touching you.

Try this

Check where the Moon is today (a quick search works). Then ask three questions: what sign is it in, does that feel like a style I’d enjoy today, and what’s one small thing I could do in that style? If the Moon is in a gentle sign, take a slower walk. If it’s in a bold one, say the thing you’ve been rehearsing.

Next: make a star map of the real sky above any place and moment.
