Saturn is the slowest planet you can see with the naked eye. It needs about 29 and a half years to go once around the zodiac. So it spends a little over two years in each sign on average. But it does not spend the same time in every sign. I measured it over 27 full laps of Saturn, from 1613 to 2408, and Capricorn comes out on top, tied with Sagittarius. Saturn sits in Capricorn 9.21 percent of the time. A fair share would be 8.33 percent, one part in twelve. Gemini and Cancer, the low end, get only 7.51 percent each.
The reason is not mystical. It is orbital. Saturn is farthest from the Sun, and so moves slowest, when it crosses the first few degrees of Capricorn. This page gives you that measure, the method behind it, and the exact dates of every stay from 1900 to 2100. If you want to know whether you have this placement, the dates are the answer.
Do you have Saturn in Capricorn? Every stay from 1900 to 2100
Saturn returns to Capricorn about every 29.5 years. Each visit lasts close to three years. Most visits are not one clean run, though. Saturn goes retrograde once a year. Retrograde means the planet seems to drift backwards against the stars for about four and a half months. Nothing reverses in space. Earth simply overtakes Saturn on the inside lane, the way a slower car seems to slide back as you pass it. When that backward drift happens near a sign border, Saturn steps out of the sign and comes back.
Here is every crossing between 1900 and 2100. Times are in UTC, rounded to the nearest minute.
| Stay | Saturn enters Capricorn | Saturn leaves Capricorn | Where it goes. |
| 1900 to 1903 | 21 January 1900, 08:10 | 18 July 1900, 17:33 | Back into Sagittarius. |
| 1900 to 1903 | 17 October 1900, 05:03 | 19 January 1903, 22:15 | On into Aquarius. |
| 1929 to 1932 | 15 March 1929, 13:48 | 5 May 1929, 04:19 | Back into Sagittarius. |
| 1929 to 1932 | 30 November 1929, 04:22 | 24 February 1932, 02:47 | On into Aquarius. |
| 1929 to 1932 | 13 August 1932, 11:14 | 20 November 1932, 02:10 | Into Aquarius for good. |
| 1959 to 1962 | 5 January 1959, 13:32 | 3 January 1962, 19:01 | Into Aquarius, in one clean run. |
| 1988 to 1991 | 13 February 1988, 23:51 | 10 June 1988, 05:22 | Back into Sagittarius. |
| 1988 to 1991 | 12 November 1988, 09:26 | 6 February 1991, 18:51 | On into Aquarius. |
| 2017 to 2020 | 20 December 2017, 04:49 | 22 March 2020, 03:59 | Ahead into Aquarius. |
| 2017 to 2020 | 1 July 2020, 23:36 | 17 December 2020, 05:04 | Into Aquarius for good. |
| 2047 to 2050 | 24 January 2047, 15:41 | 11 July 2047, 02:59 | Back into Sagittarius. |
| 2047 to 2050 | 22 October 2047, 11:09 | 21 January 2050, 13:16 | On into Aquarius. |
| 2076 to 2079 | 3 December 2076, 16:03 | 28 February 2079, 17:26 | Ahead into Aquarius. |
| 2076 to 2079 | 2 August 2079, 12:26 | 27 November 2079, 14:20 | Into Aquarius for good. |
Read the table like a map of birth dates. If you were born inside one of those windows, your natal Saturn is in Capricorn. If you were born in a gap, it is not. A birth on the very day of a crossing needs the hour and the place, because the times above are UTC. A baby born in New York at 8 p.m. on 19 December 2017 was born on 20 December in UTC, one hour before Saturn crossed. That child has Saturn in Sagittarius.
The gaps matter as much as the stays. Take mid 1988. Saturn left Capricorn on 10 June and came back on 12 November. A child born in September 1988 has Saturn at the end of Saturn in Sagittarius, not in Capricorn. Many quick lookups give the whole of 1988 to 1991 as one block. They are wrong for about five months of births.
How long each stay really lasts
I counted the days Saturn spent inside the sign on each visit. The span from first entry to final exit is longer, because it includes the weeks outside during a backward drift.
| Stay | Days inside Capricorn | Span from first entry to last exit | Number of crossings. |
| 1900 to 1903 | 1,003 days | 1,094 days | Four crossings. |
| 1929 to 1932 | 965 days | 1,346 days | Six crossings. |
| 1959 to 1962 | 1,094 days | 1,094 days | Two crossings. |
| 1988 to 1991 | 934 days | 1,089 days | Four crossings. |
| 2017 to 2020 | 991 days | 1,093 days | Four crossings. |
| 2047 to 2050 | 990 days | 1,093 days | Four crossings. |
| 2076 to 2079 | 934 days | 1,089 days | Four crossings. |
The shortest stay held 934 days. The longest held 1,094. The median, the middle value, is 990 days, or two years and eight months. The 1959 visit is the odd one out. It was the only one of the seven with no step back at all. Saturn walked in on 5 January 1959 and walked out almost three years later to the day. The 1929 visit is the other extreme. It crossed the border six times, and the whole span ran to three years and eight months.
Why Saturn slows down in Capricorn
Saturn’s path around the Sun is not a circle. It is an ellipse, a stretched circle. At its far point, called aphelion, Saturn is about 10.07 times as far from the Sun as Earth is. At its near point, called perihelion, it is about 9.01 times as far. Johannes Kepler worked out the rule in 1609. A planet sweeps equal areas in equal times, so it crawls at the far end and hurries at the near end. For Saturn, the gap in speed around the Sun is about 25 percent.
Now the key fact. Every aphelion of Saturn between 1900 and 2100 fell with Saturn in the first five degrees of Capricorn, seen from the Sun. Here are the dates from my run.
| Aphelion, rounded to the month | Where Saturn stood, seen from the Sun. |
| July 1900 | About 2 degrees of Capricorn. |
| November 1929 | About 2 degrees of Capricorn. |
| May 1959 | About 3 degrees of Capricorn. |
| September 1988 | About 2 degrees of Capricorn. |
| April 2018 | About 4 degrees of Capricorn. |
| July 2047 | About 2 degrees of Capricorn. |
| March 2077 | About 4 degrees of Capricorn. |
The near point sits on the other side of the circle, in the first few degrees of Cancer. So Saturn moves slowest in late Sagittarius and early Capricorn, and fastest in late Gemini and early Cancer. That is why Sagittarius and Capricorn share the top spot, and why Gemini and Cancer share the bottom.
Here is the full count, over 27 full laps of Saturn. Each lap runs from one entry into Aries to the next.
| Sign | Share of time with Saturn there, 1613 to 2408. |
| Capricorn | 9.21 percent of the time. |
| Sagittarius | 9.19 percent of the time. |
| Aquarius | 9.01 percent of the time. |
| Scorpio | 8.92 percent of the time. |
| Pisces | 8.64 percent of the time. |
| Libra | 8.48 percent of the time. |
| Aries | 8.10 percent of the time. |
| Virgo | 8.01 percent of the time. |
| Taurus | 7.72 percent of the time. |
| Leo | 7.70 percent of the time. |
| Gemini | 7.51 percent of the time. |
| Cancer | 7.51 percent of the time. |
Turn those shares into days. One orbit of Saturn lasts about 10,759 days. Capricorn gets about 990 of them. Cancer gets about 807. That is a gap of six months per lap. So Saturn in Capricorn is not rare. It is in fact among the two most common Saturn signs.
Do not read too much into the gap between first and second place. Capricorn beats Sagittarius by 0.02 points on this window. Over ten laps, from 1849 to 2143, Capricorn led by 0.03 points. Over 26 laps, from 1613 to 2378, Sagittarius edged ahead by less than 0.01 points. Call it a tie. What holds on every window I tried is the shape: those two signs on top, Gemini and Cancer at the bottom.
How I measured it, so you can redo it
A figure no one can check is worth nothing. Here is the recipe.
First route. I used the astronomy-engine library, which computes planet positions from the VSOP87 theory of the planets. For each moment, I took Saturn’s position as seen from Earth, corrected for light travel time. I turned it into a longitude on the ecliptic of date. The ecliptic is the Sun’s yearly path across the sky, and the longitude is the distance along it, counted from the spring equinox. That is the tropical zodiac, the one used on this site. I stepped through time every two days. Each time the sign changed, I closed in on the exact moment by halving the interval, down to one second. Then I added up the time between crossings, sign by sign.
Second route. I asked JPL Horizons, the ephemeris service of NASA’s Jet Propulsion Laboratory, for Saturn’s longitude on every day of the same 27 laps, from June 1613 to March 2408. That is about 290,000 daily positions, read for the center of mass of Saturn and its moons. I counted the time per sign. The two routes agree within 0.01 points for every sign.
For the crossing times in the first table, I used Horizons as the reference. I found each crossing on an hourly grid, then on a one minute grid. The first route lands within 25 minutes of Horizons on every crossing but two, both in 1900, where the gap reaches 59 minutes. Saturn moves so slowly that a tiny error in position turns into minutes on the clock. Times after 2040 carry an extra doubt of a minute or so. They depend on a forecast of Earth’s spin, which slows by tiny steps that no one can predict exactly.
Why ten orbits? A short window can lie. Sixty years hold about two laps of Saturn, and the start and end dates decide which signs get an extra visit. I chose a window that starts and ends with Saturn entering Aries, so every sign gets exactly ten visits.
The aphelion dates come from the first route. I tracked Saturn’s distance from the Sun every ten days and kept the peaks.
What the old books say about Saturn here
Capricorn is Saturn’s own sign, and it has been for two thousand years. Claudius Ptolemy set out the scheme in the Tetrabiblos, written in Alexandria around 150 AD. Each of the five visible planets gets two signs. One is its day house and one is its night house. For Saturn, Aquarius is the day house and Capricorn is the night house. Vettius Valens, writing a few decades later in his Anthologies, keeps the same pairing. William Lilly repeats it in Christian Astrology in 1647. A planet in its own sign is said to be in domicile. Think of a host at home, free to run the place its own way.
The opposite signs, Cancer and Leo, are Saturn’s detriment, where it works like a guest in someone else’s house. Its exaltation, a place of honour, is Libra. Its fall, the sign of least ease, is Aries.
Here is a detail worth pausing on. The sign where Saturn moves slowest today is its home. The sign where it moves fastest, Cancer, is its detriment. That match is neat, and it is also a coincidence of our era. The far point of the orbit drifts forward by one or two degrees per century. My run puts it near the end of Scorpio around 100 AD. So Ptolemy could not have used it, and did not. He built the scheme from the seasons and the order of the planets. Keep the two facts apart: the rulership is tradition, the slow pace is physics.
Capricorn hosts two other planets with strong status. Mars is exalted there, at 28 degrees. Jupiter is in its fall there, at 15 degrees. Where Jupiter joins Saturn in this sign, the chart pairs a planet at full strength with one at its weakest. That happened for 280 days in 2020.
The company Saturn keeps on each visit
Saturn never visits alone. The slower planets set the backdrop, and they change from one stay to the next. This is where two people with Saturn in Capricorn, born thirty years apart, part ways.
1929 to 1932. Pluto sat opposite, in Cancer. I found three exact oppositions: 17 February, 8 July and 13 December 1931, each with Saturn near 20 degrees of Capricorn. An opposition means two planets face each other across the circle.
1959 to 1962. No outer planet shared the sign. Uranus was in Leo, Neptune in Scorpio and Pluto in Virgo. This is the cleanest version of the placement in the century, with one straight run and no crowd.
1988 to 1991. This is the crowded one. Saturn spent 934 days in Capricorn. On 898 of them, Uranus and Neptune were in Capricorn too. So most people born in those years carry three planets in the sign. Saturn met Neptune three times: 3 March, 24 June and 13 November 1989, all near 11 degrees of Capricorn. You can read more on Uranus in Capricorn. One common claim needs a fix. The three meetings of Saturn and Uranus in 1988 all fell in the last degrees of Sagittarius, not in Capricorn. The first came on 12 February 1988, one day before Saturn crossed.
2017 to 2020. Pluto was in Capricorn on every one of the 991 days. Saturn met Pluto on 12 January 2020, at about 23 degrees of Capricorn. Jupiter shared the sign for 280 of those days. Then Saturn left on 17 December 2020. Four days later, on 21 December, it met Jupiter at just under half a degree of Aquarius. That meeting belongs to Saturn in Aquarius, not to this sign. More on the backdrop sits in our page on Pluto in Capricorn.
2047 to 2050 and 2076 to 2079. By then Pluto has moved on to Pisces and then to Aries. Saturn will stand in Capricorn without an outer planet beside it, much as it did in 1959.
Reading Saturn in Capricorn in a real chart
The sign tells you how Saturn works. The house tells you where. A house is one of twelve slices of the chart, each tied to one area of life. Our planet of structure guide covers the planet in general. Here is what the home sign adds.
In the old reading, a planet in domicile acts with its full means. For Saturn, that means order, time and limits, used on purpose rather than suffered. Liz Greene, in Saturn: A New Look at an Old Devil, reads Saturn as the place where you feel lack and then build skill to cover it. In its own sign, that building has good tools. Stephen Arroyo makes a similar point. He sees Saturn as the part of the chart that asks for effort and pays back in solid form.
Sect changes the tone. Sect sorts charts into day births and night births, by whether the Sun was above the horizon. Chris Brennan and Demetra George both explain the Hellenistic rule. Saturn belongs to the day team. In a day chart, it is milder and more useful. In a night chart, it is out of sect and harder to carry. So Saturn in Capricorn in a night birth reads as a strong Saturn with a heavy hand. In a day birth, it reads as a strong Saturn working in your favour.
The house counts too. In the tenth house, the house of career and public name, Saturn in its home sign doubles the theme of rank and duty. Our page on Saturn in the tenth house goes into it. In the fourth house, the same Saturn turns to home and family. That pattern shows up in the Capricorn man, whose caution in love follows the same Saturn timetable.
One caution. A strong Saturn is not a cold person. It is a person who keeps promises, and who wants the same from others. Warmth comes once trust is earned. Robert Hand, in his book Planets in Transit, treats each Saturn transit as a test of what you have built. With Saturn at home in your chart, those tests hit ground that is already firm.
Your Saturn return with this placement
Your Saturn return is the moment Saturn comes back to the exact spot it held when you were born. It first lands between age 28 and 30. With Saturn in Capricorn at birth, your return always falls in the next Capricorn stay. People born in 1959 to 1962 had their first return in 1988 to 1991 and their second in 2017 to 2020. People born in 1988 to 1991 had their first return in 2017 to 2020. Their second is due in 2047 to 2050. Babies born in 2017 to 2020 meet theirs in 2047 to 2050 as well.
Because Saturn is slow in this sign, a return here takes a bit longer to play out than one in Gemini or Cancer. The exact dates for your birth year sit in our guide to the Saturn return and when yours lands.
Where this fits with your Sun sign
Saturn in Capricorn is not the same as being a Capricorn. Your Sun sign comes from your birthday in the year. Your Saturn sign comes from your birth year. Most people with Saturn in Capricorn have a Sun in some other sign. For the sign itself, its dates and its traits, see our page on the Capricorn sign.

Frequently asked questions
When was Saturn last in Capricorn?
From 20 December 2017 to 22 March 2020, then again from 1 July to 17 December 2020, in UTC. It will not be back until 24 January 2047.
How long does Saturn stay in Capricorn?
Between 934 and 1,094 days per visit from 1900 to 2100, with a median of 990 days. That is close to two years and eight months.
Is Saturn in Capricorn rare?
No. It is one of the two most common Saturn signs. Saturn sits there 9.21 percent of the time over 27 full laps, from 1613 to 2408, against 7.51 percent for Gemini and Cancer.
Why does Saturn spend more time in Capricorn?
Saturn is farthest from the Sun, and so slowest, when it crosses the first degrees of Capricorn. Every aphelion from 1900 to 2100 fell there.
Is Saturn strong in Capricorn?
In the old scheme, yes. Capricorn is Saturn’s night house in Ptolemy, Valens and Lilly, so Saturn is in domicile there. Sect then decides whether that strength feels easy or hard.
I was born in 1988. Do I have Saturn in Capricorn?
Only if you were born between 13 February and 10 June, or after 12 November. Births from mid June to mid November 1988 have Saturn in Sagittarius.
