Nodal Return, Saturn Square, Uranus Opposition: Ages

Saturn first comes back to its birth degree between the ages of 28.4 and 29.9. Uranus first reaches the point opposite its birth degree between 38.1 and 44.5, and Neptune first stands 90° past its birth degree between 38.8 and 42.1. Pluto’s square has no settled age at all: it came at 35.5 for a birth in August 1969 and comes at 52.3 for a birth in January 2001. The mean lunar node is back where it started after 18.6 years for everyone, and again at 37.2 and 55.8.

Each figure comes from a census of 720 births, one on the 1st of every month from January 1950 to December 2009 at noon IST, with the four planets followed day by day through the JPL DE421 ephemeris until it runs out in October 2053. Positions are tropical, measured from the equinox, because these events are a Western way of counting; a section further down shows what changes in the sidereal zodiac of an Indian chart. Ages are in years from the birth date, to one decimal (a tenth of a year is about five weeks).

Squares, Oppositions and Returns Defined

In Western transit work these events are measured between a planet in the sky and the same planet in the birth chart. When the moving planet has gone 90° beyond its birth longitude it is called the waxing square; at 180°, the opposition; at 270°, the waning square; and back at 360°, the return. Modern Western practice applies the same names to the node, so a nodal return is the node back at its birth longitude. Everything on this page is that geometry and nothing more. Searches for these events often ask what they signify for a person, and the page does not answer: a table of ages and dates offers no way of testing a reading, so it gives none for any of them.

The Age at Each Event, and How Many Passes

Saturn’s four events fall in a fixed sequence: first pass of the waxing square at 5.7 to 8.2, of the opposition at 12.8 to 16.3, of the waning square at 20.9 to 23.4 and of the return at 28.4 to 29.9, every birth in the census meeting them in that order. Uranus’s waxing square comes at 18.4 to 23.2. The last column is the stretch from the first exact pass to the last, for events with more than one; a single pass is a single date. For 101 births, all from 2001 on, Pluto’s square falls after the ephemeris ends, and for 15 more the passes are still under way when it ends, so those are left out of Pluto’s pass counts and spans but not its ages.

Saturn’s return in particular is the subject of an older page on this site, Saturn return at 29; the census adds the spread of ages around that number, and the fact that 63% of births get a single pass.

Why One Event Can Have Three or Five Passes

Seen from the Earth, each of these planets spends part of every year retrograde, moving backwards against the stars before it turns forward again. If the target degree lies inside the stretch that one of those loops covers, the planet crosses it going forward, again going backwards, and a third time going forward; that is a three-pass event. When the target lies in the overlap of two successive loops, it is crossed five times, and the event runs across two retrograde seasons, more than a year from first pass to last. The slower the planet, the larger the share of births whose target degree lies inside a loop, as the census shows. Saturn’s squares and opposition split close to evenly, with a single pass for 44 to 51% of births, and Saturn’s return is single-pass for 63%. Uranus has three passes at its opposition for 93% of births and never five. Neither Neptune’s square nor Pluto’s is ever a single pass: three for 73% and 69% of births respectively, five for the rest.

Saturn’s loops, along with those of Mercury to Jupiter, are listed on the site’s retrograde dates pages, and the stations of Uranus, Neptune and Pluto from 2026 to 2028 are on the outer-planet retrograde page.

How Long a Uranus Opposition Lasts

Counted from the first exact pass to the last, a three-pass Uranus opposition lasts 259 to 297 days in the census, with a median of 289: about 9.5 months. A three-pass Saturn return is shorter, with a median of 261 days. For the 7% of births with a single pass the opposition is one date. An astrologer who counts an orb, a band of degrees either side of the exact point, will quote a longer period, and how long depends on the orb chosen; this page counts exact passes only, which is its own choice and not a rule.

Pluto’s Square Moves by Years

Pluto’s orbit is far from circular, so it crosses some signs much faster than others, and the age at which it gets 90° past its birth position depends heavily on where it started. A January 1950 birth met the square at 40.9. The age then fell, to a low of 35.5 for the August 1969 birth, and has climbed since: 52.3 for a birth in January 2001, 16.8 years later in life than the youngest case. For five of the 2001 births and every birth from 2002 on, the square falls after October 2053, beyond the ephemeris, and so later still in life. Neptune, on a near-circular orbit, keeps its square inside 3.3 years of age for every birth in the census.

Nodal Return Ages

The Moon’s node comes in two versions, set out more fully on the north node sign by birth date page. The mean node is the node of an averaged lunar orbit and slides backwards at one fixed rate, so its return age is the same for every birth: 18.6 years, which puts the second nodal return at 37.2 and the third at 55.8. The true or osculating node is taken from the Moon’s actual orbit at each instant and wobbles to either side of the mean one. For the 60 January births in the data, its first return comes between 18.56 and 18.78 years, from 19 days before the mean return to 61 days after it. It is a single crossing for 97% of them; the 1970 and 2008 births had three. Software set to the true node will therefore give a slightly different date for the same birth.

By Birth Year, 1950 to 2009

Each cell gives the age at the first pass for a birth on 1 January of that year, then in brackets the youngest and oldest age among that year’s twelve births. The spread inside one birth year reaches 1.5 years for Saturn’s return and 2.3 for Uranus’s opposition, so for a birth in any other month the bracket is the better guide. To find your own, look up your birth year, or for a closer value the two census births either side of your birthday; the planets’ signs for each birth year are on the Uranus, Neptune and Pluto sign dates page.

First Passes Due Between Now and the End of 2028

Of the census births, these will have the first exact pass of each event after 28 October 2026 and on or before 31 December 2028:

• Saturn return: births of Jun 1997 to Nov 1997, Feb 1998 to Jun 1999 and Jan 2000 to Feb 2000 (25 census births; first passes from 19 March 2027 to 6 August 2028)
• Uranus opposition: births of Jan 1983 to Jul 1983, Oct 1983 to Dec 1984 and Aug 1985 to Sep 1985 (24 census births; first passes from 28 May 2027 to 5 September 2028)
• Neptune waxing square: births of Feb 1986 to Jun 1986, Dec 1986 to Jan 1988 and Jul 1988 to Dec 1988 (25 census births; first passes from 6 April 2027 to 22 June 2028)
• Pluto waxing square: births of Dec 1985 to May 1986, Oct 1986 to Dec 1986 and May 1987 to Oct 1987 (15 census births; first passes from 18 February 2027 to 10 April 2028)

The months missing between the runs are births whose first pass came before 28 October 2026 or will come after 2028. Separately, some census births had the first pass before 28 October 2026 with more passes still to come after it: 4 for the Saturn return, 11 for the Uranus opposition, 13 for the Neptune waxing square and 12 for the Pluto waxing square.

Tropical or Sidereal: How Far the Dates Move

The angle between a planet and its own birth position is nearly the same in either zodiac, because each position is shifted by the ayanamsa of its own date. Nearly, not exactly: the ayanamsa grows by about 50 arcseconds a year, which on the site’s Lahiri formula comes to 0.56° over 40 years. A sidereal opposition therefore needs Uranus to travel that much further, and at the census’s average pace for Uranus (one circle in about 84 years) that takes about 48 days. So the shift is weeks, not days. Worked the same way at each event’s own average age, the sidereal first pass comes about 12 days later for Saturn’s return, 50 for Uranus’s opposition, 93 for Neptune’s square and 91 for Pluto’s. These use an average speed: a pass made near a station, where the planet is barely moving, can shift by more. The site’s Jupiter return census measured the same effect for that faster planet, a few days on average, and found that the zodiac can also change the number of passes.

What This Page Does Not Give

Ages, dates and pass counts only. No event here is described as good, hard or important, nothing is said about what anyone might do or feel at these ages, and none of them is offered as a reason to time a decision. The census births are at noon; a different birth time starts each planet from a slightly different longitude, which matters most for a pass made near a station. Dates are good to about a day and no time of day is printed.

In Brief

• Uranus opposition length: 259 to 297 days from first to last pass, or a single date
• Neptune square: 38.8 to 42.1; Pluto square: 35.5 to 52.3 within the ephemeris
• Nodal return: 18.6, 37.2 and 55.8 years (mean node); the true node’s first return within about two months of it
• Sidereal dates: later than tropical by about 12 days (Saturn return) to 91 and 93 days (Pluto and Neptune squares)
