Your horoscope says, "Saturn is squaring your Moon this week." You nod like you understand. You don't, quite, and it's a little unsettling.
The short answer: a transit is where a planet is in the sky right now, compared with where the planets were when you were born. Your birth chart stays fixed. The planets keep moving, and each time one touches a point in your chart, astrologers call that a transit. Here is how to read one in three questions.
The idea: two skies
Imagine two photographs of the sky. One is from the moment you were born. That's your natal chart. The other is today's sky. A transit is the conversation between them: today's Jupiter is meeting my birth Venus.
Most astrologers treat transits as themes, not fixed outcomes. They show what a stretch of time is about, and you choose what to do with it.
Three questions to read any transit
1. Which planet is moving?
The moving planet is the "energy." The faster it moves, the shorter its effect.
Planet | Roughly how long it spends in a sign | What it tends to feel like |
|---|---|---|
Moon | 2–3 days | Mood of the day |
Sun | About a month | The theme of the season |
Mercury, Venus | A few weeks | Conversations, relationships, taste |
Mars | 6–7 weeks | Drive, friction, energy |
Jupiter | About a year | Growth, openings |
Saturn | About 2.5 years | Structure, responsibility, testing |
Uranus | About 7 years | Change, surprise |
Neptune | About 14 years | Dreams, dissolving, confusion |
Pluto | 12–30 years | Deep transformation |
The slow planets are the ones astrologers talk about for big life chapters. The fast ones shape your day-to-day mood.
2. What does it touch?
A transit means something when the moving planet meets a point in your chart: one of your natal planets, or a house. A Jupiter transit to your natal Venus is about love and value. A Saturn transit to your natal Moon is about mood and security. The point it touches tells you which part of you is being asked a question.
3. At what angle?
The angle between the moving planet and your natal point is called an aspect. It sets the feel of the transit.
Angle | Name | The feel |
|---|---|---|
0° | Conjunction | Intense, a new start |
60° | Sextile | Easy opportunity |
90° | Square | Friction that pushes you to act |
120° | Trine | Flow, support |
180° | Opposition | Tension, a mirror, balance |
A transit is strongest when it's exact, and it's usually felt within a few degrees on either side. The slow planets can move over the same point more than once in a year, because they appear to slow down, turn retrograde, and come back. So a big transit often shows up as a chapter with a beginning, a middle and a second pass.
Which part of life: the house
Last, ask which house the moving planet is crossing. The house is the area of life: home, work, love, money, friends. A planet crossing your 7th house puts partnership in the spotlight. Crossing your 10th, it's career. Your houses depend on your birth time, so check your rising sign in your natal chart first.
A reading you can do in one minute
Take the sentence "Saturn is squaring your Moon" and run it through the questions:
Which planet? Saturn: structure, responsibility, slow.
What does it touch? Your Moon: your moods and what you need to feel safe.
What angle? A square: friction that pushes you to act.
Put together: a stretch where your sense of security is being tested, and where you are pushed to build something steadier. It's a theme, not a verdict. You can use it: tidy the routines that make you feel safe, and be kind to your mood.
You can use the same format for anything:
[Planet] [angle] my [point], in my [house]: this is a time about ___ for my ___.
Moon, Venus and the daily ones
The Moon makes transits every day, which is why your mood can shift so fast. Venus and Mercury move through your chart in weeks. When one of them turns retrograde, like in our Venus retrograde 2026 guide, it re-crosses the same points, so you get a second look at the same themes.
Our astrology calendar 2027 lists next year's Moon phases, eclipses and Mercury retrogrades, so you can see the fast-moving transits coming.
The Five Elements version
Timing also reads Five Elements, the Chinese system that reads your birth date as a mix of Wood, Fire, Earth, Metal and Water. It has its own idea of "what's passing through": each year and each ten-year stretch brings its own element, and it interacts with the mix you were born with. It's the same idea as a transit, seen from another tradition. You can see your mix on our Five Elements page.
Where Timing fits
Doing this by hand means comparing a birth chart with the sky every day, and no two charts give the same result. Timing does the comparison for you. Add your birth details once, and it reads your chart against today's sky and your Five Elements, then shows you how your day looks. Astrologers tune our readings and choose every tool inside Timing, and the AI explains the result so you don't have to decode a symbol. Open it in the morning and see what the sky is saying to you.

What is the difference between a transit and an aspect?
An aspect is the angle between two planets, like a square or a trine. A transit is a moving planet making an aspect to a point in your birth chart.

Most astrologers treat them as themes. They show what a period is about, and you choose what to do with it. They aren't fixed outcomes.
How do I see my transits?
You need your birth date, time and place to make a birth chart, then compare it with the current sky. Timing's app does the comparison each morning.
