Stationary Planets at Birth: Station Retrograde and Station Direct

← Back to Planets

A station is the moment a planet's apparent motion along the zodiac reverses. Before a station retrograde the planet is moving forward and slowing down; after it, the planet is moving backward. A station direct is the opposite turn, at the end of a retrograde stretch. Around either turn the planet barely moves for a while, which is why astrologers describe it as stationary and why some of them give a planet born near its station extra attention.

This page explains what a station is, what the free birth chart does and does not show about it, and how to measure how close a birth was to one. If the word retrograde is new to you, start with what a natal retrograde is.

What the calculator does here: it shows a planet as retrograde (℞ on the wheel, R in the planet list) or with no marker. There is no "stationary" label, no station table and no speed figure on the chart. Stations are an astrological and astronomical concept this page discusses; they are not something the free chart outputs.

How the chart decides at the turn

For each planet the calculator works out its longitudinal speed, the rate at which its position along the zodiac is changing at the birth moment. If the speed is below zero, the planet gets the R. If it is zero or above, the planet is shown as direct. So the label flips at the station itself, and a speed of exactly zero counts as direct.

The speed comes from the calculator's own positions. For Mercury through Neptune, and for Pluto, it compares the position one hour before and one hour after the birth moment. For Chiron it interpolates between speeds stored once a day. The station times on this page come from the same routines, searched for the instant where that speed changes sign. They are the model's station times, quoted to the minute. Another ephemeris can put the same station a little earlier or later, so treat a time within a few minutes of a station as a close call rather than a settled fact.

Two practical consequences follow:

• Two people born a few hours apart, either side of a station, see the same degree on the chart but different labels.
• Nothing on the chart tells you that a planet was close to its turn. A planet shown direct may be one minute from turning retrograde.

Two births either side of a turn

Mercury turned retrograde on 1 April 2024. In the calculator's model the station fell at 23:14 British Summer Time (BST), with Mercury at 27°13' Aries. Ada and Ben are fictional people, both born in London (51.5074, -0.1278), and their Mercury positions come from the calculator.

The minute-by-minute check agrees: a chart for 1 April 2024 in London shows Mercury direct at 23:14 and retrograde from 23:15. Both speeds are tiny. At its fastest, Mercury covers about two degrees a day, so at birth both Ada's and Ben's Mercury were moving less than a hundredth of that rate.

The chart gives Ada no hint that her Mercury was about to turn, and gives Ben no hint that his had only just turned. If either of them reads about stations, the useful fact is the time distance from the turn and its direction: Ada was born before a station retrograde, Ben after it.

Why a degree alone cannot tell you

It is tempting to measure closeness to a station in degrees: "my Mercury is 7° from where it stationed." The trouble is that a planet crosses most of the degrees in its retrograde stretch three times. It passes forward, then backward, then forward again.

In spring 2024 Mercury stationed retrograde at 27°13' Aries and direct at 15°58' Aries on 25 April (13:54 BST). Every degree between those two points was crossed three times. The calculator's routines put Mercury at exactly 20° Aries at these moments (London time):

Three births at these moments would all show Mercury at 20°00' Aries, each about 7° from the retrograde station point, yet they were born at very different stages of the loop. Only the date and time place each one: before the turn, in the middle of the backward run, or after the turn forward. So a degree distance from a station point does not tell you how close the birth was to the station in time, or on which side of it.

Slow planets and long pauses

Slow planets hover for much longer. Saturn turned direct on 15 November 2024, at 14:20 Greenwich Mean Time (GMT) in the model, at 12°41' Pisces. Here is Saturn on London noon charts around that turn:

Over these eleven days Saturn's printed position changed by two arc minutes. At noon on 12 November its speed was -0.005° a day and at noon on 18 November +0.005° a day. The label flipped at a single minute: a chart for 15 November shows R at 14:20 and no R from 14:21. Someone born on 15 November at 09:00 and someone born there on 16 November at 09:00 share a Saturn degree but not a label.

That is why "how many days from the station" says more for a slow planet than "how many minutes of arc". Around this turn, Saturn's noon position stayed within about 6' of its station degree from 4 to 25 November 2024, three weeks in all, so a degree gap is tiny for many births that are days apart.

No cut-off is adopted

Astrologers do not agree on how near a station a birth must be to count as "stationary". Some use a day or two for Mercury, others a week or more for the slower planets, and some scale the window to each planet's speed. Astrologist.com does not adopt any of these windows, and this page does not set one. What it reports is a measurement: how much time separates a birth from the nearest calculated station, and whether the birth came before or after it.

How to check your own chart

1. Write down your birth date, local time and place, and the planet you are curious about. A reliable birth time matters here; without one, see retrograde planets without a birth time.
2. Find that planet's station dates and times for your birth year in any ephemeris or station table. Note the time zone those times are given in, usually Universal Time.
3. Convert the station time to the local clock time of your birthplace, including any summer time in force on that date. The time zones and daylight saving guide covers the usual traps.
4. Subtract: how many hours or days separate your birth from the nearest station, and was it a station retrograde or a station direct?
5. Compare the R on your free birth chart with that result. If the station is within a few minutes of your birth time, both the label and the station time are close calls.

Reading a planet born near a station

In many traditions a planet near its station is read as concentrated: its themes are said to show up with more weight, as though the planet were lingering on one point. A planet just past a station retrograde is sometimes described as turning its themes inward; one just past a station direct as starting to express them outward again. These are common associations, not rules. They do not predict events, and they do not make a planet stronger or weaker by any measure the chart computes.

Read the planet in the usual order first: sign, house if you have a reliable time, and its major aspects. Then add the station as one more note, if you find it useful. The planet guides for Mercury, Venus, Mars, Jupiter and Saturn and the outer planets cover the R itself.

Why stations happen where they do, well away from the planet's conjunction or opposition with the Sun, is explained on retrograde planets and the Sun. How often each planet is retrograde at all is on how common retrograde planets are. If you would like to talk a station through, you can ask the Astrologist with your chart open.
