Free South Node Calculator

The South Node is the descending point where the Moon's orbit crosses the ecliptic from north latitude to south latitude, and it is always exactly opposite the North Node.[1] The nodal axis moves backward through the zodiac by about one sign every eighteen months and completes a circuit in about 18.6 years.[2]

Modern authors give that astronomical point different weight. Jan Spiller reads the South Node as an overemphasized response inherited from past lives, one that tends to take over when you act without awareness.[3]Familiar past patterns can also form firm foundations, in Schulman's account, and support present achievement as readily as they can limit it.[4] Elizabeth Spring revised her earlier North Node emphasis and treats the South Node as a past life story that carries suffering and earned wisdom.[5]Both skill and blind spots can sit inside the automatic pattern in Forrest's account.[6] Spiller, and Schulman in part, read the South Node as the overused response. Spring treats it as both gift and story. Forrest sits between them because the established pattern carries real skill yet can stay automatic enough to create blind spots. The calculator identifies the point; the South Node guide develops the interpretation.

Read the two nodes as one line through the chart. Spiller's chapters describe the whole nodal axis even when their headings foreground the North Node.[3]Balance and reciprocity between the developed South Node end and the North Node faculties still being cultivated are central to Teal's reading.[7] Jeffrey Wolf Green describes the two ends as past and present modes of operation serving an evolutionary intention.[8] The arc between the nodes carries the meaning for Mark Jones, who objects when either end is judged in isolation.[9] A Scorpio South Node therefore gives a Taurus North Node at the same degree.[1]The pair sets established responses beside a contrasting field of practice, a reciprocity central to Teal's reading.[7]

The glyphs preserve the older names. Melanie Reinhart identifies the North Node as Caput Draconis, the Dragon's Head, and the South Node as Cauda Draconis, the Dragon's Tail.[10]The South Node glyph (☋) sets two small circles above an open arc. The North Node glyph (☊) inverts it, with the arc above the circles. Their mirrored shapes make the opposition visible. The karmic synastry calculator checks nodal contacts between two charts, while the draconic chart calculator places the North Node at zero degrees Aries.

These authors share the same astronomical point and assign different meanings to it. Their definitions range from an overused response to an inherited capacity, while the traditional row applies a separate increase and decrease rule.

Astrologers have not settled on one frame. Spiller uses the true node, while Marilyn Muir has found value in both and provisionally prefers the true node.[3][12] Teal and Reinhart both settle on the mean node, Teal for natal and progression work, Reinhart with a true node check near boundaries.[7][10]Spring follows the mean through her teachers' lineage.[5]The mean node also anchors Forrest's teaching method.[13]

We lead with the true node and show the mean node beside it. The true node is the Moon's osculating orbital node computed from the DE440s planetary ephemeris through ANISE, referred to the true equinox of date. The mean node uses the standard linear formula: longitude 125.04452 minus 1934.136261 times the Julian centuries from J2000. The two frames can separate by up to about two degrees. Between 1930 and the last sampled date, they sit in different signs on 62 separate stretches of days, all within a few weeks of a sign boundary. The true node is sampled through September 3, 2026; later dates in the generated range assume the mean node.

This table shows the true South Node sign for every birth year from 1930 through 2026. Years with a sign change are split into dated segments, so a calendar year can contain more than one South Node sign. The North Node appears beside each South Node because the two points always form one opposite pair. True node positions are sampled through September 3, 2026, and every table date refers to noon UTC. Frame notes identify dates when the generated true and mean node signs differ. Those notes matter most for births near zero or twenty-nine degrees of a sign. The table is a date guide rather than a substitute for a chart calculation. Enter your birth date above for the exact degree. Add a recorded birth time and place for the full house-based result and its ruler.

As of October 18, 2026, the South Node is in Leo.

The true node is sampled through September 3, 2026. The next changes below use mean node dates through 2030.

• Mean node date: March 7, 2028, South Node enters Cancer.
• Mean node date: September 25, 2029, South Node enters Gemini.

The house places the South Node pattern in a field of activity. Forrest describes the house as the area you enter through an effortless pull, while the sign describes the motive and manner of that pull.[6]Teal's description of the first house South Node centers excessive independence and self-absorption, with partnership as the balancing field.[7]Schulman shows the reverse pairing through a seventh house South Node, where identity can become submerged in a partner's view.[4] These are tendencies within an axis, so the opposite house remains part of the reading. Your exact birth time matters because the rising sign anchors the houses. Without a known time, the calculator can still give the sign and degree, while the house remains unresolved. The twelve links below lead to the full house guides; their labels draw on Celeste Teal, Jan Spiller, and Martin Schulman.

Find the planet that traditionally rules the South Node sign, then read that planet's sign and house. Green says the ruler adds the area and manner that helped the South Node's prior mode operate.[8]Schulman gives a narrower rule for mutual reception: when a nodal ruler occupies the opposite node's sign, past material becomes necessary to the present direction.[4] This calculator uses Mars for Aries and Scorpio, Venus for Taurus and Libra, Mercury for Gemini and Virgo, the Moon for Cancer, the Sun for Leo, Jupiter for Sagittarius and Pisces, and Saturn for Capricorn and Aquarius. The result card names the traditional ruler. The twelve sign readings below name Pluto with Scorpio, Neptune with Pisces, Uranus with Aquarius, and keep the traditional ruler first where it differs.

Past life readings carry different levels of certainty. Spring treats Evolutionary Astrology as a many lives model, yet she limits a South Node reading to an emotional and spiritual narrative rather than a recoverable biography.[5] Forrest suspends judgment between reincarnation and genetic inheritance because both models describe dispositions brought forward from the past.[6] You can therefore use past life language literally or as a way to examine old, automatic patterns. The chart supplies themes for reflection rather than proof of a specific former identity.

Medieval western doctrine uses another rule. Abu Ma'shar and al-Qabisi describe the Dragon's Head as increase and the Dragon's Tail as decrease, so the South Node can reduce the good of a benefic or reduce the harm of a malefic.[14] In Vedic astrology the South Node is Ketu and the North Node is Rahu; Reinhart presents those as the Indian names for the eclipse axis.[10] The nodes complete an 18.6 year circuit[2][11], and Doser rounds the figure to 18.5 years. This places nodal returns around ages 18 to 19, 37 to 38, and 55 to 56. The nodal return calculator gives the dates for one birth chart.
