Transits: today’s sky against your chart
A birth chart never changes. The sky changes every day. A transit is the angle between the two, and it is where everything this site calls “today” comes from.
Two charts laid over each other
Picture two circles. The first is your birth chart: ten bodies frozen at the minute of birth, permanently. The second is the sky right now, the same for everyone on the planet. Lay them over each other and look at where bodies of the second form angles with bodies of the first. Those are transits.
The rules are the same as for aspects inside a chart: the same six angles, the same orbs. There is nothing new to learn.
An example: the sky against that same chart
- ♄ □ ♆transiting Saturn — square to natal Neptune, orb 0.7°
- ♃ □ ♇transiting Jupiter — square to natal Pluto, orb 0.9°
- ♄ ☌ ♂transiting Saturn — conjunction to natal Mars, orb 2°
- ♇ △ ☿transiting Pluto — trine to natal Mercury, orb 2.4°
- ♃ □ ♀transiting Jupiter — square to natal Venus, orb 2.5°
- ♃ · ☽transiting Jupiter — quincunx to natal Moon, orb 1.2°
The six strongest on September 13, 2026. The next day the list is different — which is why transits are computed each time rather than stored.
Six rows out of the thirty-odd found that day. Not picked at random: the site weighs a transit by two things — how exact the angle is and how slow the body is. A Moon transit lasts hours, a Saturn transit months, and treating them as equal would be dishonest.
Fast and slow
The difference in scale is the main thing here, and the thing most often left unexplained:
- The Moon — hours. It changes sign every two and a half days, so its transits are what makes today unlike yesterday.
- Sun, Mercury, Venus — days. About a month per sign.
- Mars — weeks.
- Jupiter and Saturn — months. These are what people usually mean by “a period in life”.
- Uranus, Neptune, Pluto — years. A transit of one of these to your Sun happens once or twice in a lifetime and lasts longer than it is remembered as lasting.
So the daily horoscope here is built mainly from the Moon: it is the only body that manages to change within a day. The slow planets are background.
Where the text on a sign page comes from
The order is this. Overnight the sky for the day is computed. For each of the twelve signs the angles from that sky to the sign’s arc are taken: where the Moon is, at what angle, what the sign’s ruler is doing, whether a slow planet is pressing. The text is written from those numbers — and next to it stands a “computed from” block with the same lines.
A Sun-sign horoscope is the coarse version: it takes a thirty-degree arc instead of your Sun’s exact degree and knows nothing of the other nine bodies. So a sign page answers “what about today in general”, and a chart answers “what about today for me”.
The Saturn return
The best-known transit in the tradition, and the only one with an exact schedule, because it depends on a single number: Saturn completes an orbit in about twenty-nine and a half years. So at roughly that age it comes back to where it stood in your chart — and again at about fifty-nine.
The tradition reads it as a passage between stages: the first return ends youth, the second ends mid-life. How far that holds is yours to judge; what is certainly true is the number itself. You can check it in half a minute in any astronomical reference.
Three questions for any transit
If you do not know where to start, these three questions give more than any table of meanings:
- Which body is transiting? That sets the scale: hours, weeks or years.
- What is the orb? An exact angle is the peak; an orb at the edge of tolerance means either not yet or already over.
- Applying or separating? The first means ahead, the second means already happened. The difference between those two is bigger than the difference between a trine and a square.
What a transit does not do
It does not cause events. Saturn crossing your Sun is not arranging difficulties for you — in the tradition it corresponds to a stretch when something has to be endured. The difference is not verbal: the first reading makes you a victim of circumstance and the second does not.
And it has no day-precise schedule. A transit has an orb, so it lasts as long as the angle stays inside the tolerance: hours for the Moon, years for Pluto. Any text promising “on the 14th specifically” is promising something the system does not contain.

Transits to your chart are computed in the reading — alongside the natal aspects, with the same orbs and the same “computed from” list.
