What are transits? How today's sky meets your birth chart

Transits are where the planets are today compared with your birth chart. How they work, which ones matter most, and how daily readings are built from them.

Your birth chart is a snapshot of the sky at one moment. But the sky kept moving. Transits are where the planets are now, read against that snapshot. They’re the basis of every personal daily reading, including ours.

How a transit works

Take a planet in the sky today and compare it with a planet or point in your birth chart. If the angle between them is meaningful, astrologers call it a transit, and read it as that part of your life being touched for a while.

The angles are the same ones used in compatibility:

Angle Name Feels like
0° Conjunction A strong focus; something starts or comes to a head
60° Sextile An opening, if you act on it
90° Square Friction and pressure to change
120° Trine Ease and support
180° Opposition Tension between two sides; balance needed

Fast and slow transits

How long a transit lasts depends on how fast the planet moves:

  • The Moon changes sign every couple of days. Its transits set the mood of a day.
  • The Sun, Mercury and Venus take a few days to pass a point: themes for the week.
  • Mars lingers about a week: a burst of energy or friction.
  • Jupiter and Saturn take weeks or months, and mark longer chapters.
  • Uranus, Neptune and Pluto can take a year or more, and describe big, slow shifts.

The transits people talk about most

How our daily reading uses transits

Our app looks at the faster planets (Sun, Mercury, Venus, Mars) and the slow, important ones (Jupiter and Saturn) against your Sun, Moon, Venus, Mars and rising sign. It keeps the closest few and describes them in plain words: what’s being lit up, what might rub, and one thing to try. It adds the Moon’s sign and phase for the mood of the day, and reads it all alongside your Destiny Matrix chapter and personal year.

Reading transits sensibly

  • Transits describe pressure and opportunity, not events.
  • The same transit feels different to different people, depending on the rest of the chart and what’s going on in their life.
  • Notice which transits match your experience over time. That tells you which ones to pay attention to.

Questions people ask

What are transits in astrology?

They’re the current positions of the planets compared with your birth chart, read as themes affecting different parts of your life.

What are the most important transits?

Slow ones, such as the Saturn return, Jupiter’s movements and outer-planet transits, mark the biggest chapters. Fast ones set the tone of days and weeks.

How long does a transit last?

From a few hours (the Moon) to more than a year (Pluto), depending on the planet.

Do I need my birth time to read transits?

Not for most planet-to-planet transits. You do need it for transits to your rising sign, midheaven and houses.
