A reader's guide to today's sky on your chart
Live transits are the moving planets right now, pressed against the fixed map of your natal chart. This guide walks through the mechanics of reading today's sky on a personal chart, drawing on Robert Hand's Planets in Transit (1976), Liz Greene's work on Saturn and outer-planet themes, and the layered Hellenistic methodology of Chris Brennan and Demetra George.
Key Takeaways
- Live transits are today's moving sky in contact with the fixed floor of your natal chart, the day-to-day weather you walk through.
- Tightest orbs first: a transit within 1 degree of exact is at peak intensity. Outside 3 degrees, the theme is approaching or separating but no longer loud.
- Inner planets (Moon, Mercury, Venus, Mars, Sun) shift today's mood; outer planets (Jupiter through Pluto) carry today's slice of a multi-year chapter.
- Pair this live read with annual profections to amplify the transits to your Lord of the Year, and with the 12-month transit calendar for the broader forecast.
- In traditional Western astrology, transits describe symbolic climate, not specific events, the choices inside the weather remain yours.
What are current transits?
A current transit is a moving planet in the sky right now making an aspect to a placement in your natal chart. In traditional Western astrology, your natal chart is the fixed map of where every planet stood at the moment of your birth, and it never changes. The transits are the live weather pressing against that fixed floor, hour by hour and day by day. When transiting Mars enters within a degree of your natal Venus today, the chart suggests Mars' themes (drive, friction, desire) come briefly into contact with Venus' themes (relationship, beauty, value). When the contact separates, the theme moves on.
The reason "live" matters is that the sky never sits still. The Moon completes a full orbit in 28 days and shifts aspect every couple of hours. Mercury and Venus typically take a year to complete their cycle and shift aspect daily. The Sun moves about a degree a day. Mars and Jupiter shift over weeks. Only the slow movers (Saturn through Pluto) hold steady enough to dominate a month or a year. A live reading captures all of these layers at once, which is what no static daily horoscope can do.
Robert Hand's Planets in Transit (1976) is the modern foundational text for this practice. Hand catalogued every planet-to-planet aspect by transit and walked through what each combination tends to look like in lived experience. The book has never gone out of print and remains the reference Astrid Moon reaches for when describing what a particular transit often correlates with in a client's day. According to Chris Brennan in Hellenistic Astrology: The Study of Fate and Fortune (2017), transits in the ancient tradition were never read alone, they sat on top of a time-lord framework (profections, zodiacal releasing, annual returns) that named the year's topic first.
For the underlying floor of your chart that the transits are working against, see your free birth chart. For the year-ahead view of where the slow transits are heading, the 12-month transit calendar samples each month for the next year so you can see the bigger arc this live moment sits inside.
How to read today's sky on your chart
Once your live result loads, the natural question is what to actually do with it. The sequence below is the one Astrid teaches in workshops, adapted from Robert Hand's methodology and the layered Hellenistic technique Chris Brennan documents in his work. Reading the live sky is not about chasing every aspect at once; it is about finding the loudest two or three voices and reading them in the context of the natal placements they are touching.
Begin with orb. The list of active transits is sorted by tightness, so the top of the list is also the loudest. A transit within 1 degree of exact is at peak intensity right now, today; a transit within 3 degrees is still strong but less dramatic. Anything beyond 6 to 8 degrees has faded, even if the calculator still surfaces it. Then move to the planets involved: the slow movers (Jupiter through Pluto) carry weeks or months of weight, the inner planets (Sun, Moon, Mercury, Venus, Mars) carry hours to days. A 1-degree Saturn aspect is the headline; a 1-degree Moon aspect is a passing mood.
Finally, look at which natal planet each transit is contacting. Transits to your Sun and Moon are the most personal; transits to the Ascendant and Midheaven shape how you show up in the world and in work; transits to your natal Saturn or Mars often surface the chart's structural pressure points. In my practice with clients tracking live transits, the most useful question is not "what are all the transits today?" but "which one or two transits today actually touch a sensitive natal placement?" The rest is background noise.
Orb: how close is close enough?
An orb is the allowed degree of separation between two planets for an aspect to count as active. The closer to exact (orb 0°), the louder the theme. As the orb widens, the felt intensity drops. Most modern astrologers use different orb conventions by aspect type and by the planets involved, with conjunctions and oppositions allowed the widest orbs and minor aspects allowed the tightest.
Robert Hand, in Planets in Transit (1976), uses a roughly 1-degree orb for outer-planet transits and a slightly wider 2-degree orb for Jupiter. Liz Greene, in her practice documented across Saturn: A New Look at an Old Devil and The Astrology of Fate, treats the 1-degree orb as the moment of peak intensity for Saturn and the outer planets, with the wider 3-degree orb framing the approach and separation. Below is the orb convention this calculator uses, drawn from contemporary practice.
Orb conventions by aspect type
- Conjunction (0°)
- 8° outer, 6° inner; 1° = peak
- Opposition (180°)
- 8° outer, 6° inner; 1° = peak
- Square (90°)
- 7° outer, 5° inner; 1° = peak
- Trine (120°)
- 7° outer, 5° inner; 1° = peak
- Sextile (60°)
- 5° outer, 4° inner; 1° = peak
- Saturn / Jupiter orbs
- Use the wider end of the range
- Sun / Moon transits
- Use the tighter end of the range
- Outer planet transits
- Read 1° as the active window
In practice, the rule of thumb is simple: anything inside 1 degree of exact is the loudest contact on the chart right now, anything between 1 and 3 degrees is still active and worth reading, and anything beyond 3 degrees can be set aside unless the planets involved are very slow. According to Demetra George in Astrology and the Authentic Self (2008), tighter orbs surface the strongest contacts; wider orbs catch more events but read with less precision.
Approaching, exact, separating: the three phases
An aspect does not happen in a single moment. It unfolds in three phases: the approach (the planet moving toward exactness), the exact hit (the day the aspect peaks), and the separation (the planet moving away). Each phase carries a different felt quality, and the slower the planet, the longer each phase lasts.
In the approaching phase, the theme is building. The chart suggests this period often correlates with restlessness, anticipation, or the sense that something is coming but not yet here. Robert Hand describes the approach as the time when the theme begins to organize itself in the unconscious; events and synchronicities cluster around the eventual exact date but rarely peak yet. In Liz Greene's reading of Saturn transits, the approach is where the chart sets the conditions of the lesson before the lesson actually arrives.
The exact phase is the day the aspect peaks. For the Moon, this lasts only hours. For Mercury and Venus, a day or two on either side. For Mars, several days. For Jupiter and Saturn, the exact phase is more accurately a window of a few weeks within which the planet stays inside 1 degree of exactness. Outer planets like Saturn often produce a triple-pass on a single natal point (direct, retrograde, direct) over a 12 to 18 month window. In Howard Sasportas's reading from The Gods of Change (1989), this triple-pass is the chart's way of insisting on the theme until it has actually been integrated.
The separating phase is the integration window. The peak has passed, and the felt intensity gradually drops as the orb widens. In my practice with clients, this is often where the actual change shows up; the dramatic events of the exact phase are still echoing, and the new structure is being lived into. The chart suggests the separating phase ends when the orb crosses about 3 degrees, after which the transit has effectively ended.
For the slow transits, the entire three-phase arc can take six to eighteen months. The 12-month transit calendar visualizes these arcs at a glance; this live page shows you which phase the slow transits are in today.
Inner vs outer planet transits TODAY
Today's live result mixes two very different kinds of weather. The inner planets (Moon, Mercury, Venus, Mars, Sun) are the fast movers; their transits describe today's mood and the texture of the next few hours or days. The outer planets (Jupiter, Saturn, Uranus, Neptune, Pluto) are slow; their transits today are simply today's slice of a much longer chapter that has been unfolding for weeks, months, or even years. Reading the live result well means knowing which voice is which.
Saturn squaring your Sun today is not a one-day event; it is the Saturn return-style work that is shaping this entire calendar year (see the dedicated Saturn Return guide if Saturn is currently in your natal Saturn sign). A Moon-Venus trine today, by contrast, lasts only a few hours and shifts the mood without changing the structural chapter. According to Howard Sasportas in The Gods of Change, the outer-planet transits are the chart's built-in initiations; the inner-planet transits are the daily texture inside those longer initiations.

Mercury retrograde, live check
One of the most common reasons people open a live transit calculator is to check whether Mercury is retrograde right now. Mercury is the fastest planet other than the Moon, and its apparent backward motion through the zodiac (the planet does not actually reverse, it only appears to from Earth's vantage) happens roughly three times a year for about three weeks each.
In traditional Western astrology, Mercury retrograde is read as a review-and-revise window, not as a structural transit. Robert Hand frames it as a time when the conscious mind has the opportunity to revisit, edit, and clarify what was set in motion before, the second draft after the first draft has been written. In my practice with clients, Mercury retrograde works best as a permission slip for the editing pass, the difficult conversation you needed to have again, the contract you suspected was rushed.
Demetra George, in Ancient Astrology in Theory and Practice (2019), notes that the Hellenistic tradition read retrogrades with more nuance than modern pop astrology often does. A retrograde planet has a different essential meaning depending on whether it is in its own sign, in detriment, or near the Sun (combust). The simple modern reading (avoid signing contracts, expect tech glitches) is a folk reduction; the classical reading is more layered, treating the retrograde as a change in the planet's mode rather than a uniform warning.
When to use live transits vs the 12-month calendar
CrystalStones.com offers two complementary transit tools, and knowing when to use each is the difference between confusion and clarity. The live transit calculator on this page surfaces today's exact-orb aspects, including the fast inner-planet contacts that shift hour by hour. The 12-month transit calendar surfaces the slow-planet outlook for the next year, sampled mid-month so you can see the broader arc of Saturn, Jupiter, and the outer planets.
Use the live page for today's weather, the day's mood, the micro-timing of whether right now is the moment to send the email or wait until tomorrow. Use the calendar for the year's forecast, the question of when the next Saturn or Jupiter aspect peaks and what windows are best for big moves. Both tools draw on the same astronomical engine; they differ in lens and time horizon. According to Chris Brennan in Hellenistic Astrology (2017), the ancient tradition layered both perspectives reflexively: a daily transit reading sat inside a yearly profection inside a multi-year zodiacal release.
A worked example: suppose you are deciding whether to launch a project this week. The live transit calculator shows transiting Mercury trine your natal Mars today, at orb 0.5°. That is excellent micro-timing for a focused action this afternoon. The 12-month calendar, meanwhile, shows transiting Saturn square your natal Sun for the next eight months. That is the larger climate, and it suggests the project itself will face structural pressure regardless of when you launch this week. The two tools together produce a layered read: launch this afternoon, but plan for the slower Saturn work to shape the year.
In short, this page tells you the weather; the transit calendar tells you the climate. The chart suggests both are needed, and that reading either in isolation produces a thinner reading than the layered approach.
Reading today's transit through your profected year-lord
The deepest layer of transit reading in the Hellenistic tradition is the profected year-lord. Annual profections advance one house of the chart per year of life, starting from the rising sign at birth. The planet ruling the activated house becomes the Lord of the Year, which Chris Brennan calls the year's "internal weather system." A transit to the Lord of the Year is amplified, the year's topic itself is being touched; a transit to a non-year-lord planet, by contrast, reads as background weather.
Here is the practical mechanic for today's sky. If transiting Saturn is squaring your natal Mars today, and Mars is your Lord of the Year, then this transit lands with extra weight, the year's entire theme is colored by this single contact. If transiting Saturn is squaring your natal Mars and Mars is not your Lord of the Year this year, the transit still operates, but it functions as a sub-theme to whatever your actual year-lord is doing.
Demetra George reads this layering in Astrology and the Authentic Self (2008) as the difference between weather and climate within a single day. The transit is the weather of the moment; the profected lord is the climate of the year; the natal chart is the underlying terrain. A live transit reading without a profection reading is weather without climate, which can be misread as the whole story when it is only a slice.
Calculate your current annual profection first, then return to this page and notice which of today's transits land on your Lord of the Year. Those are the contacts that matter most this year, and the ones whose orb windows are worth tracking week by week.
Crystal pairings for today's loudest transit
Beyond the symbolic reading, each transiting planet can be paired with a crystal that anchors the day's work in something tactile. The pairings below follow Judy Hall's The Crystal Bible (2003) and Melody's Love is in the Earth (1995), cross-referenced with the planetary symbolism each crystal is traditionally associated with in modern crystal practice. These are tradition-attributed correspondences, not medical advice, crystals work as physical reminders of symbolic attention.
Transiting planet to crystal
- Sun transits
- Sunstone (joy, vitality) or Citrine (radiance)
- Moon transits
- Moonstone (lunar attunement) or Selenite (emotional clarity)
- Mercury transits
- Sodalite (clear thinking) or Blue Lace Agate (smooth communication)
- Venus transits
- Rose Quartz (heart) or Green Aventurine (relational harmony)
- Mars transits
- Carnelian (action, courage) or Hematite (channelled fire)
- Jupiter transits
- Citrine (expansion) or Lapis Lazuli (wisdom)
- Saturn transits
- Black Tourmaline (boundary) or Smoky Quartz (containment)
- Uranus transits
- Labradorite (change) or Selenite (clarity in upheaval)
- Neptune transits
- Amethyst (dream-life) or Moonstone (intuition)
- Pluto transits
- Black Obsidian (shadow work) or Hematite (anchoring)
Use the crystal as a daily anchor through the orb window of the transit. Many people find that carrying or wearing the stone during the approach and exact phases gives the day's work a physical referent, a small object that says I am paying attention to this.

How to use the live transit calculator
The five-step sequence below mirrors the HowTo schema on this page and walks through the practical use of the calculator from input to layered reading. Each step builds on the previous, and the layered reading at step five is the one Astrid teaches as the floor of professional practice.
- 1
Enter your birth date, time, and location
The calculator uses astronomy-engine to compute the live positions of all ten planets and circular-natal-horoscope-js for your natal chart. Birth time accuracy matters most for the Ascendant and Midheaven; a four-minute error can shift an angle by a full degree.
- 2
Identify the tightest aspects today
The top of the active transit list is sorted by orb tightness, with slower planets weighted ahead of faster ones. Anything inside 1 degree of exact is at peak intensity right now; anything beyond 3 degrees is fading.
- 3
Note which natal planet each transit is contacting
Transits to the Sun, Moon, Ascendant, and Midheaven are the most personal. Transits to natal Saturn or Mars often surface the chart's structural pressure points. Transits to natal outer planets carry generational themes more than personal ones.
- 4
Read the aspect phase: approaching, exact, or separating
The approach phase builds the theme; the exact hit is the peak; the separation integrates. Outer-planet transits can spend months in each phase. Inner-planet transits cycle through all three in a day or two.
- 5
Layer with your profected year-lord
Calculate your annual profection first. Transits to the Lord of the Year are amplified; transits elsewhere are background weather. This is the layered Hellenistic reading Chris Brennan walks through in Hellenistic Astrology (2017).
For a daily horoscope based on today's sky against your Sun sign (a generalized read rather than a personal one), see the daily horoscope. For the broader year ahead, the 12-month transit calendar pairs naturally with this page.
Frequently asked questions
Common questions Astrid receives from clients new to live transit reading, with the same answers indexed in the FAQ schema on this page.
What is a transit in astrology?
A transit is a moving planet in today's sky making an aspect to a placement in your natal chart. In traditional Western astrology, the natal chart is the fixed floor of your birth moment, and transits are the live weather over that floor. Robert Hand's Planets in Transit (1976) is the modern standard reference for this practice.
How is a live transit different from a 12-month transit calendar?
This page shows what is in tight orb right now, today, including the fast inner-planet transits (Sun, Moon, Mercury, Venus, Mars) that shift hour by hour and day by day. The transit calendar at /transit-calendar is the 12-month outlook focused on slow movers (Jupiter through Pluto). Use this page for today's weather and the calendar for the year ahead.
What is an aspect orb?
An orb is the allowed degree of separation between two planets for an aspect to count as active. Within 1 degree is very tight and the theme is at peak intensity. Within 3 degrees is still strong. Robert Hand uses a roughly 1-degree orb for outer-planet transits and a 2-degree orb for Jupiter; faster inner planets are typically read within a 2 to 3 degree orb.
How do I know if a transit is affecting me TODAY?
Look at the tightest orbs on your result page. A transit within 1 degree of exactness is most likely to be felt in lived experience today. Outer-planet transits inside that 1-degree orb can stay active for weeks; inner-planet transits inside the orb are usually only active for a day or two. The closer to exact, the louder the theme.
What's the difference between approaching, exact, and separating phases?
Every transit unfolds in three phases. Approaching means the moving planet has not yet reached the exact aspect and the theme is building; the felt sense is often anticipatory or restless. Exact is the day the aspect peaks. Separating means the planet has passed the exact degree and the theme is integrating. Slow planets can spend months in each phase; the Moon's aspects last only hours.
What's the loudest transit on my chart right now?
The top result on this page is sorted by importance: tighter orbs first, with slow-moving outer planets weighted ahead of fast inner planets. The chart suggests the first listed transit is the year's headline if it involves an outer planet, or the day's headline if it involves an inner planet. Read it as the loudest current voice in your chart's choir.
How do I read multiple transits at once?
Read them as one composite weather pattern, not as separate events. In my practice with clients, if Saturn is squaring your Sun and Venus is trining your Moon in the same week, the period reads as structural pressure on identity layered with relational softness underneath. The combination produces a felt texture that no single transit captures alone.
Is Mercury retrograde right now?
Check this page. Mercury's status (direct or retrograde) is shown next to its current position in the Sky Right Now panel. Mercury is retrograde roughly three times a year for about three weeks each. For the full schedule of upcoming retrogrades, see the dedicated Mercury Retrograde guide.
What does it mean if Saturn is transiting my Sun today?
Saturn transits to the natal Sun classically mark a chapter of structural pressure on identity and direction. Liz Greene, in Saturn: A New Look at an Old Devil, frames Saturn's contact with the Sun as the work of becoming more fully responsible to who you are. The chart suggests this is rarely a single day's event; the transit will be within orb for weeks or months around exactness.
What does it mean if Jupiter is transiting my Venus today?
Jupiter transits to natal Venus typically expand the relational and aesthetic life. Robert Hand, in Planets in Transit, reads this contact as a time of openness, social ease, and often noticeable benefit in love or money. The chart suggests the window is real but limited; Jupiter moves on, and the lift is best treated as an opportunity rather than a guarantee.
How long does a typical transit last?
Slow planets stay within tight orb for weeks or months. Saturn within 1 degree of a natal point typically lasts six to eight weeks. Jupiter within 2 degrees lasts about three to four weeks. Mars within 2 degrees lasts about a week. Mercury, Venus, and the Moon move through and out of orb in hours or a day or two.
Can I 'wait out' a difficult transit?
Outer-planet transits cannot be waited out the way a Mercury retrograde can; the chapter has to be lived through. Liz Greene cautions in The Astrology of Fate against trying to dodge the symbolic work of a transit. The wiser approach is to learn the theme, do the work it asks for, and let the orb separate naturally. The transit is the climate, not a punishment.
How do transits relate to my horoscope?
A daily horoscope is a generalized read of today's sky against your Sun sign. Personal transits, which this page generates, contact every position in your chart specifically. The horoscope is the weather forecast for everyone of your sign; live transits are the weather forecast for you alone, using your birth time and location.
What's the difference between a transit and a natal placement?
The natal placement is fixed at birth and describes a permanent feature of your chart, your Sun in Pisces or your Mars in the 10th house. A transit is temporary and describes a moving planet making aspect to that natal placement today. Natal placements are the floor; transits are the weather over the floor.
Should I use live transits or progressions for daily timing?
Live transits are the better tool for daily and weekly timing. Secondary progressions are a symbolic technique (one day after birth equals one year of life) and move very slowly; the progressed Moon, the fastest progressed point, moves about one sign every two and a half years. Demetra George reads progressions as complementary to transits, with transits surfacing daily weather and progressions surfacing inner-life chapters.
