Saturn-Neptune Conjunction: Every Date from 1900 to 2100 and Who It Touched

A Saturn-Neptune conjunction is the moment Saturn and Neptune sit at the same degree of the zodiac, and it comes round every 35 to 37 years. The latest one was on February 20, 2026 at 11:52 a.m. EST (8:52 a.m. PST), at 0°45′ Aries, and it was a single exact pass. The one before it was 1989 (three passes in Capricorn), and the next is June 7, 2061 at 20°24′ Gemini. This page lists every pass from 1900 to 2100, the four phases of the cycle with their dates, and who was born close to each meeting. Dates use the Western tropical zodiac and US Eastern time unless marked UTC.

Every Saturn-Neptune conjunction, 1900 to 2100

We found the moments when the difference between Saturn’s and Neptune’s apparent ecliptic longitude reaches 0°, using the Swiss Ephemeris. Neither planet moves in a straight line as seen from Earth, because both go retrograde for part of each year. When a meeting happens near Saturn’s turn, the two can pass three times in one year instead of once, which is what happened in 1952-53 and 1989.

We checked all ten passes against NASA’s JPL Horizons service, using its Saturn and Neptune barycenter bodies and their apparent ecliptic longitudes from Earth’s center. For every pass Horizons found the crossing within one to eight minutes of ours; the gap is under three minutes through 2026 and widens in 2061 and 2096, the far edge of what is predicted. We also compared the 1917 to 1989 rows, degree by degree and date by date, with the appendix of A. E. O’Neill’s 2005 PlanetWaves article, and every date and degree matched (O’Neill gives July 22, 1953, which is our UTC date). Earlier meetings, by our calculation: March 28, 1703 (Aries), July 2, 1738 (Cancer), September 27, 1773 (Virgo), December 1, 1809 (Sagittarius), 1846 (three passes in Aquarius, April 4, September 5 and December 11 UTC) and May 12, 1882 (Taurus). The Astrology Podcast’s list of year-only conjunctions (1773, 1809, 1846, 1882, 1917, 1952/53, 1989) agrees.

The 2026 conjunction: one pass and a near miss

Neptune crossed into Aries for the last time on January 26, 2026 at 12:40 p.m. EST, after a first visit from March 30 to October 22, 2025. Saturn followed on February 13, 2026, and the two met seven days later at 0°45′ Aries. They did not meet again: Saturn’s retrograde, from July 26 to December 10, 2026, brings it back to 7°56′ Aries, still about 6.3° ahead of Neptune on December 10.

The reason 2026 is a single pass and 1989 was triple is timing against Saturn’s loop. In 1989 the first pass (March 3) came while Saturn was still direct, the second (June 24) while both planets were retrograde, and the third (November 13) once Saturn was direct again. In 2026 the meeting fell in February, well before Saturn’s retrograde began, and Saturn had pulled away by the time it turned.

The summer of 2025 is worth knowing about because it often gets counted as a conjunction. On July 16, 2025 Saturn stood at 1°55′ Aries and Neptune at 2°08′ Aries, 0.21° apart. Saturn had turned retrograde on July 13 and the gap opened again, so there was no exact pass. Counting it, the planets were within 1° of each other from June 9 to August 24, 2025 and again from February 8 to March 5, 2026, which is why some writers describe the conjunction as running for a year or more. See our Saturn in Aries guide for Saturn’s own ingress dates and the house table for your rising sign.

As of October 14, 2026, Saturn is at 10°31′ Aries moving backward and Neptune is at 2°30′ Aries, 8.0° apart. The separation stays under 10° until March 2, 2027, so the “within 10°” window below is still open to births. For where Neptune sits for your birth year see Uranus and Neptune signs by birth date.

The cycle: conjunction, square, opposition, square

Astrologers split the roughly 36-year cycle at the angles 90°, 180° and 270° between the two planets. The table gives the first and last exact pass of each phase for the three completed cycles (1917, 1952-53 and 1989), the one that began in 2026 and the one after it. A square is a 90° angle and an opposition is 180°; each usually takes three passes because of the retrograde loops, but not always (the 1963 square and the 2026 conjunction were single).

Counted from the first pass, the 1989 cycle reached its square about 9.3 years later (June 25, 1998), its opposition at 17.5 years (August 31, 2006) and its waning square at 26.7 years (November 26, 2015). The cycle that began in 2026 hits the same checkpoints in 2033, 2042 and 2052. The 2042-43 opposition has five passes, which ties the 1899-1900 opposition for the most passes (five) of any phase we found.

What comes next, 2026 to 2061

These are the exact passes still ahead of us, calculated the same way. We checked each date against JPL Horizons at daily resolution, and Horizons agreed on the day for every pass in the table.

Neptune does not leave Aries until 2038-39: it first reaches Taurus on May 22, 2038, steps back to Aries on October 21, 2038 and moves on for good on March 23, 2039. So the sextile and the square fall with Neptune in Aries; by the 2042-43 opposition it is in Taurus. Saturn will meanwhile have left Aries on April 12, 2028; see your Saturn sign by birth date for where it is in your chart.

Who was born close to a conjunction

There is no single agreed orb, so we give three measures: within 1°, within 5° and within 10° of an exact conjunction, using the Saturn-Neptune difference on the day of birth. A window can be split because the retrograde loops carry the planets in and out of range; gaps are marked. Ages are as of October 14, 2026.

The 1989 group, born between December 23, 1988 and January 18, 1990 (ages 36 to 37), has Saturn and Neptune within 5° of each other in Capricorn and are turning 37 as the 36-year cycle closes. The 2026 group is now infants. The 1952-53 group (within 5° of each other from September 22, 1952 to October 8, 1953) is aged 73 to 74.

The US births data we use for other Numyra studies, the CDC and Social Security Administration files, begins in 1994, so we cannot count how many Americans were born inside the 1989 window, and 2026 births are not yet published. We have not estimated them.

Which phase you were born in

Every person was born during one of the four quarters of the cycle, which tradition treats as a generational mood: how far Saturn is ahead of Neptune in the sky on your birthday. The dates use first exact passes, so birthdays within a few months of a boundary can fall either side.

What tradition says about the cycle

In modern mundane astrology, the study of nations and societies, Saturn stands for structure and Neptune for dissolution and ideals. One modern reference puts it this way:

Saturn builds, defines, and maintains structuresKerykeion, Saturn-Neptune Cycles in Mundane Astrology

The same page says Neptune dissolves and imagines, and treats the conjunction as the seed of a new cycle, the squares as tests, and the opposition as the point of greatest tension. Another source, A. E. O’Neill quoting Eric Francis, calls it:

one of history’s most important clocks to watchEric Francis, quoted in A. E. O’Neill, “Heavy Water: The Saturn-Neptune Cycle”

Writers commonly attach events to each meeting: the Russian Revolution to 1917, the death of Stalin to 1952-53, and the fall of communist governments in Eastern Europe to 1989. The US State Department’s historian describes that last event this way: the Berlin Wall fell on November 9, 1989. On our dates that was four days before the third and last exact pass on November 13, and about four and a half months after the second, so the “conjunction year” matches only loosely to any single day. Associations like these are chosen after the fact, from a long history with many events available, and we treat them as tradition, not evidence of cause. For the sign pairing now in play see Pluto in Aquarius and the Uranus opposition, two other slow cycles running alongside this one in the 2020s.

The 2026 pass is an unusual start to a cycle because it falls at 0°45′ Aries, within the first degree of the tropical zodiac, so astrologers who count the zodiac from there describe it as a reset. That reading belongs to the tradition and cannot be tested.

Frequently asked questions

When was the last Saturn-Neptune conjunction?+

February 20, 2026 at 11:52 a.m. EST (8:52 a.m. PST, 16:52 UTC), at 0°45′ Aries. Before that, 1989 had three passes (March 3, June 24 and November 13) in Capricorn.

How many exact passes did the 2026 conjunction have?+

One. Saturn came within 0.21° of Neptune on July 16, 2025 but turned back, so 2025 was a near miss, and in 2026 Saturn pulled away before its own retrograde began.

When is the next Saturn-Neptune conjunction?+

June 7, 2061 at 12:08 a.m. EDT (04:08 UTC), at 20°24′ Gemini, a single pass. After that comes August 27, 2096 at 8°09′ Virgo.

How often do Saturn and Neptune meet?+

About every 36 years. The gaps between first passes from 1917 to 2096 are 35.2 to 37.0 years, averaging 35.8.

Who is most affected by the 2026 conjunction?+

Astrologers usually look at natal planets or angles within a few degrees of 0°45′ Aries, and at planets near 0° to 2° of Cancer, Libra and Capricorn, which sit at 90° and 180° to it. People born within 5° of the conjunction (April 8, 2025 to April 20, 2026) will have it in their birth chart. No orb is standard, and any effect is a matter of tradition.

What is the next Saturn-Neptune aspect after the conjunction?+

A single waxing sextile on June 27, 2031 at 15°30′ Gemini (Saturn) and Aries (Neptune), then the waxing square in 2033-34, the opposition in 2042-43 and the waning square in 2052-53.

Did the Berlin Wall fall at a Saturn-Neptune conjunction?+

It fell on November 9, 1989, between the second pass (June 24) and the third (November 13) of the 1989 conjunction. Astrologers link the two, but the match is a reading made afterward, not a measured cause.

Are Saturn and Neptune still close together now?+

On October 14, 2026 they are 8.0° apart (Saturn at 10°31′ Aries, Neptune at 2°30′ Aries). Their separation stays under 10° until March 2, 2027.
