Your transit chart: current astrology transits, live

Your birth chart is a snapshot that never changes. The planets kept moving after you were born, and transits are the angles they make to that snapshot today. That is how astrologers talk about timing: why this month feels heavy, or why a door suddenly opens.

On the wheel above, your natal planets sit on the inner ring and today’s planets on the outer ring, with lines for the aspects between them.

The table lists every transit within orb of a natal point, tightest first. Each row gives the date it is exact and whether it is applying, still building, or separating, already on its way out.

The Moon, Sun, Mercury and Venus set the tone for a day or a week. Jupiter, Saturn, Uranus, Neptune and Pluto mark the longer chapters, sometimes holding one aspect for months and passing over the same point two or three times as they go retrograde.

The free version shows today. With Plus you get a timeline you can drag forward and back across the coming months, watching the planets move around your wheel, with every exact aspect marked so you can see what is coming and when it peaks.

Plus also includes a written transit reading: the overall climate, the contacts that stand out, and what is building versus fading.

Transits to the Moon and the angles need an accurate birth time. The section below explains which transits still work without it.

If you are not sure of your time, check the birth certificate before you read anything into the angles.

The most useful thing to know when reading any transit is how fast the moving planet travels, because speed sets the duration. The Moon covers a degree in about two hours, so a lunar transit lasts an afternoon. Mercury and Venus take roughly a day per degree at average speed. Mars is slower, and a Mars transit is usually read across a week or two.

The slow planets are a different scale entirely. Jupiter takes about a month to cross the six degrees around an exact contact, so a Jupiter transit is a matter of weeks. Saturn takes around three months of forward motion, then usually goes retrograde back over the same point and comes forward a third time: roughly a year with three exact dates. Uranus, Neptune and Pluto stretch that further still, and a Pluto transit to a natal point can run for two or three years.

This is why the same aspect means completely different things depending on who is making it. The Moon square your Sun is a mood; Saturn square your Sun is a chapter. When two sources appear to disagree about what a square means, they are very often reading different planets at different speeds and are both right.

A transit does not switch on at the moment of exactness. Astrology works with an orb, a tolerance in degrees around the exact angle, and the transit is considered active across that whole range. Sigastra uses a tight orb for transits so the timeline stays useful, but even a tight orb means the effect builds before the date and fades after it.

The practical shape is a curve rather than a switch. The transit becomes noticeable as the planet enters orb, peaks at exactness, and eases off as it separates. If you wait for something to happen on the exact date and decide astrology has failed when nothing does, you have misread the date: it is the peak of the curve, not an appointment.

Retrograde motion complicates it in a useful way. When a slow planet stations retrograde inside the orb, it crosses the same point three times (forward, back, forward again), and the tradition reads those three passes as a sequence: something arrives, gets reconsidered, then settles. The three dates can be calculated years in advance; what fills them cannot.

Transits to your Sun, Mercury, Venus, Mars and the slow planets work from a birth date alone, to about a degree. Those placements move slowly enough that a few hours of uncertainty does not move them meaningfully, so a chart without a time still produces a usable transit list for most of the planets.

Transits to the Moon, the Ascendant and the Midheaven are a different matter. The Moon covers about thirteen degrees a day and the Ascendant a whole sign every two hours, so an hour of error can put both in the wrong place entirely. Without a reliable time, those transits cannot be timed reliably, so we leave them out rather than guess.

The same limit applies to house-based transit readings. Saying that a transit falls in your seventh house is a statement about the houses, and the houses rotate with the Ascendant. If your birth time is uncertain, the sign-based half of a transit reading still holds and the house-based half is the part to treat carefully. Treating them differently is simply more accurate than pretending both are equally reliable.

One more thing the timeline cannot show you: transits do not arrive one at a time. On any given month several are in orb at once, and the way they combine matters more than any of them alone. A Jupiter transit inside a Saturn transit reads as growth that has to be earned; the same Jupiter transit on its own reads as an opening. Reading the strongest transit in isolation is the most common way a technically correct list produces a misleading conclusion.
