“Saturn is squaring my Sun — how long will this last?” It’s the natural follow-up to every transit reading, and the answer matters: a three-day Moon transit asks for a journal entry, while a two-year Pluto transit asks for a life strategy. Duration is what turns transit information into transit wisdom.
This guide breaks down how long transits last by planet, why some transits hit three times, and how to read the timeline of any transit you’re experiencing.
Duration by Planet: The Short Version
How long a transit’s exact aspect lasts depends on the transiting planet’s speed:
- Moon: hours. A Moon transit to a natal planet lasts part of a day — mood weather, not climate.
- Mercury, Venus: days to ~2 weeks. Brief seasons of mental or relational flavor.
- Sun: ~2–3 days of exact contact, part of the annual cycle through your chart.
- Mars: days to ~2 weeks (longer when retrograde). Short bursts of drive or friction in the contacted area.
- Jupiter: weeks to a few months of close contact; ~a year in each sign. Expansive seasons you can actually plan around.
- Saturn: months of close contact; ~2.5 years per sign. The restructuring seasons — long enough to build something real.
- Uranus: many months to over a year of close contact; ~7 years per sign. Change arrives in waves.
- Neptune: a year or more of close contact; ~14 years per sign. Dissolution so gradual you may not notice until you look back.
- Pluto: 1–3 years of close contact; 12–30 years per sign. Transformation at tectonic speed.
But “exact contact” isn’t the whole story. A transit is typically felt across a wider orb — often considered active within 5–8° of exact for slow planets — which can extend the experienced season well beyond the exact dates. And then there’s retrograde…
Why Some Transits Hit Three Times
Slow planets (Jupiter through Pluto) periodically appear to move backward — retrograde — from Earth’s perspective. When a transiting planet goes retrograde near one of your natal planets, it typically crosses that point three times:
- First pass (direct): the theme arrives. Something enters your awareness — an event, a realization, a disruption.
- Second pass (retrograde): the theme goes inward. Review, reconsideration, dealing with what the first pass surfaced. Often the most psychologically intense phase.
- Third pass (direct again): resolution and integration. You act on what you’ve understood; the season completes.
A Saturn transit that would last months as a single pass can span 9–12 months across three passes. A Pluto transit’s triple-pass can stretch over two years or more. This is why “how long does it last” needs the retrograde-aware answer: check whether the transiting planet stations retrograde during the contact.
The three-pass rhythm is also interpretively useful: it describes a natural arc of encounter → integration → resolution that mirrors how humans actually process big changes. Our retrograde calendar tracks when each planet stations.
Orb: The Felt Edges of a Transit
A transit isn’t “on” only at the exact degree. Astrologers use orbs — a range of degrees around exactness — to describe when a transit becomes active:
- Approaching (applying): the transit builds as the planets move toward exactness. Many people report feeling a transit before it’s exact — the themes constellate in advance.
- Exact: the peak — often (not always) when events or realizations cluster.
- Separating: the transit fades as planets move apart. Integration phase; the season’s meaning settles.
For slow-planet transits, a working orb of ~5° approaching to ~3° separating gives a realistic felt window. That turns a “Saturn square Sun exact March 15” into “a Saturn-square-Sun season roughly December through June, peaking in March.” The season framing is almost always more useful than the date.
Overlapping Transits: Reading the Chord
Real life rarely serves one transit at a time. You’ll often have two or three significant slow-planet transits overlapping — say, Jupiter trining your Moon (expansion, warmth) while Saturn squares your Sun (testing, responsibility) simultaneously.
Read overlaps as a chord, not a conflict: life genuinely contains both currents at once. The Jupiter transit doesn’t cancel the Saturn one; they describe different life areas (or different facets of the same area) operating simultaneously. “A season of professional testing alongside personal warmth and support” is a coherent, common human experience — and more honest than picking one transit as “the” story.
When prioritizing overlaps, weight by: slower planet first (Pluto outranks Jupiter), tighter orb first (exact beats approaching), and personal planets contacted (transits to Sun/Moon/Venus/Mars usually feel more personal than to Jupiter/Saturn).
How to Map Any Transit’s Timeline
- Find the exact date(s) — one pass or three? Check for retrograde stations during the contact.
- Add the orb window — roughly 5° approaching, 3° separating for slow planets; convert to dates (about 1° ≈ 1–2 weeks for Saturn, longer for outer planets).
- Name the three phases — encounter, integration, resolution — and note where you are in the arc.
- Check overlaps — what else is active? Read the chord.
- Translate duration into strategy: days → ride it out mindfully; months → plan around it; a year+ → build with it (Saturn rewards construction; Pluto rewards surrender to necessary change).
The Bottom Line
Transit duration runs from hours (Moon) to years (Pluto), with retrograde triple-passes extending slow-planet contacts into months-long arcs of encounter, integration, and resolution. Read the orb window, not just the exact date; read overlapping transits as chords; and match your response to the timescale — mindfulness for days, planning for months, building for years.
