Astrological Transits: What They Are and How to Read Them

An astrological transit is a planet's real position in today's sky compared with your birth chart. When a moving planet reaches a sensitive point in your chart, such as your Sun, your Moon or an angle, astrologers say it is transiting that point, and they read the meeting as a theme active in your life for as long as the contact lasts.

Your birth chart is fixed: it records where everything was at the moment you were born. The planets kept moving. Right now Saturn, Jupiter and the rest are somewhere in the zodiac, and each one is forming angles to the planets in your chart. That is why the same week can feel easy for one friend and heavy for another. The sky is the same; the charts it touches are not.

What is a transit in astrology?

A transit is the contact between a planet as it moves today and a planet, angle or house in your natal chart. It has three parts:

• The transiting planet: the one moving in the sky now, which brings its own nature. Saturn brings structure and limits, Jupiter growth, Mars drive.
• The natal point it touches: the part of you being acted on. A transit to your Moon reaches your emotional life; a transit to your Venus reaches love and what you value.
• The aspect between them: the angle, such as a conjunction, square or trine, which sets the tone of the conversation. The guide to aspects covers each one.

A simple image helps. Your chart is the map and transits are the weather moving across it. The weather means little until you know which part of the map it is falling on.

Transits, progressions and solar returns

Transits are one of several timing methods astrologers use, and they are the only one based on where the planets actually are today.

• Transits compare the real, current sky with your natal chart.
• Secondary progressions are symbolic: each day after your birth stands for one year of your life, so the sky on your 30th day of life describes your 30th year.
• A solar return is a chart cast for the moment each year when the Sun comes back to its exact natal position, which can fall a day either side of your birthday.

A common teaching convention says transits describe outer circumstances and progressions inner development. The astrologer Robert Hand calls this "a very common theory" in Planets in Transit. It is a useful starting point, not a law.

How long transits last

How long a transit lasts depends on the speed of the moving planet. Fast planets pass a point in hours or days; slow ones stay for months or return to it over years.

• The Moon spends about two and a quarter days in each sign, so its transits colour moods over a day or two.
• The Sun spends about a month in each sign, and Mercury and Venus usually a few weeks, though a retrograde can stretch that.
• Mars usually spends six to seven weeks in a sign, and up to about six months when it turns retrograde.
• Jupiter spends about a year in each sign, so its transits mark chapters of a year or so.
• Saturn spends about two and a half years in each sign. Its contacts with your planets are the ones people remember.
• Uranus, Neptune and Pluto take seven years, fourteen years and anywhere from about twelve to thirty years per sign. Their transits describe eras rather than events.

There is no fixed rule for how close a transit must be to count. Robert Hand wrote that "strictly speaking, there is no such thing as an 'orb' of influence concerning a transit", and in practice many astrologers allow a few degrees for the slow outer planets and much less for the fast ones. The closer to exact, the louder the theme.

Why some transits happen three times

A slow planet can cross the same point in your chart three times because of retrograde motion. Saturn and the outer planets each turn retrograde for several months every year; Saturn's retrograde lasts about four and a half months. If one of those turns happens near your natal planet, the transiting planet crosses it going forward, backs over it, then crosses it a final time.

Many transits make only one exact pass. Whether you get one or three depends on where the stations fall, which is why the dates are worth looking up in an ephemeris rather than guessed from an age bracket. When there are three, people often describe the first pass as the issue arriving, the second as the review and the third as the resolution.

How to read a transit, step by step

Reading a transit well means following it back into your own chart. Five questions do most of the work:

1. What is the transiting planet? Its nature sets the theme: Saturn asks for commitment, Jupiter offers room, Uranus brings change, Neptune softens edges, Pluto goes deep.
2. Which natal planet or point does it touch? That is the part of your life being worked on.
3. Which houses does that natal planet occupy and rule? They show where the theme turns up in your days. The 12 houses explains each life area.
4. Which house is the transiting planet moving through? That adds the setting for the whole period.
5. Did your birth chart already link these two planets? A transit that repeats a natal aspect tends to bring an old theme back with more force.

Robert Hand adds a practical point: a long outer-planet transit is often timed by the faster planets that hit the same point along the way. The slow transit sets the chapter; the quick ones mark the scenes.

A worked example

Say your natal Moon is at 14° Cancer in your 4th house, and transiting Saturn reaches 14° Aries, making an exact square to it. Saturn's nature is structure and responsibility. The Moon is your emotional needs and sense of home. The 4th house is family and where you live.

Read together: a stretch when home life asks for more care and more structure than usual. It might mean taking on more responsibility for a parent, setting firmer routines, or deciding what kind of home you actually need. If Saturn makes three passes, the theme runs for most of a year. If your Moon already squares Saturn in your birth chart, it is a familiar lesson, back for a deeper round.

The transits astrologers watch most

Astrologers tend to watch the slow transits first, because they describe the chapter you are in:

• Saturn's cycle: roughly every seven years Saturn makes a hard angle to its own natal place (square, opposition, square), with the Saturn return arriving between about ages 28 and 30.
• The Jupiter return: about every twelve years, a fresh start in Jupiter's own themes.
• Midlife transits: the Uranus opposition in the early forties and the Neptune square at around 40 to 42.
• Outer planets crossing personal points: Uranus, Neptune or Pluto on your Sun, Moon, Ascendant or Midheaven.
• Eclipses and stations falling on or near your natal planets.

Some astrologers also use annual profections, a Hellenistic technique that gives each year of life a house and a ruling planet, and then watch transits involving that planet most closely.

Mercury retrograde and other retrogrades

A retrograde is the apparent backward motion of a planet as Earth overtakes it, or as it overtakes Earth. Mercury does it three or four times a year for about three weeks at a time, which is why it is the one everyone talks about.

Read a retrograde like any other transit: by where it falls in your chart. Mercury retrograde through your 3rd house of conversation or your 10th house of work matters more to you than one passing through a quiet corner of your chart. Most astrologers treat retrogrades as times for review, revision and returning to unfinished things, rather than for starting from scratch.

Frequently asked questions

What transits am I going through right now?

The transits you are going through right now are the angles today's planets make to the planets and angles in your birth chart. To find them you need your natal chart, ideally with a birth time for the houses and angles, and today's planetary positions from an ephemeris. Start with Saturn, Jupiter and the outer planets, since they describe the longer chapters.

How long does a transit last?

A transit lasts as long as the moving planet stays close to your natal point. A Moon transit passes in hours, a Mars transit in days, and a Saturn transit can run for months. When Saturn or an outer planet turns retrograde nearby, the same transit can stretch across most of a year in three exact passes.

Why does a transit happen three times?

A transit happens three times when the moving planet turns retrograde near your natal point. It crosses the point going forward, moves back over it during the retrograde, then crosses it again once it turns direct. This is common with Saturn, Uranus, Neptune and Pluto, but many transits make only one exact pass.

What is the difference between a transit and a progression?

A transit uses the planets' real positions in today's sky and compares them with your birth chart. A secondary progression is symbolic: it treats each day after birth as one year of life and reads the chart for that day. Many astrologers use transits for outer events and progressions for inner development, often side by side.

Start with your birth chart

A transit only means something against the chart it touches. Before you follow what the sky is doing now, know where your own planets sit: their signs, their houses and the aspects between them. Your birth chart shows all of it, with a reading written for that chart, and the guide to the planets explains what each one brings when it moves.
