True Node vs Mean Node
Reviewed by María Blaquier
Published July 16, 2026 · Updated August 9, 2026
If you have opened your draconic chart next to another site's and found a planet sitting in a different sign, nothing is broken. Both charts are almost certainly calculated correctly. They are answering the same question using two different definitions of the same point: the Moon's North Node.
We use the true node. Several other calculators, including Astro-Seek's draconic tool, use the mean node. The gap between the two is small, usually a degree or so, and in an ordinary birth chart you would probably never notice it. A draconic chart amplifies it, because the node is the one point the entire chart is built from.
The short answer
A draconic chart is made by subtracting the North Node's longitude from every point in your birth chart. That lands the node at 0 degrees Aries and carries everything else along with it.
So whatever number you use for the node gets subtracted from all of it. Change the node by one degree and you change every placement by exactly one degree, in the same direction, at the same moment. The chart does not rearrange itself. It slides.
The slide only becomes visible when a planet was already sitting close to the edge of a sign. Then a single degree is enough to carry it across the line, and a Sun that reads 28 degrees Leo on one site reads 0 degrees Virgo on the other.
Two ways to define one point
The lunar nodes are the two places where the Moon's orbit crosses the Earth's path around the Sun. That orbit does not hold perfectly still. The Sun tugs at it, and the orbital plane wobbles.
The true node is the node of that wobbling orbit, measured at the exact moment you were born. Because the wobble is real, the true node speeds up, slows down, comes to a full stop, and even moves forward for a few days at a time before resuming its backward motion.
The mean node smooths the wobble away. It is the average position, drifting backward at a steady three arcminutes a day and completing its circuit in 18.6 years. It never stops and it never turns forward.
Both are legitimate. They describe the same axis at different resolutions.
Where the two nodes cross the sky
In her video on the true node and the mean node, María starts a step earlier than most explanations, with what a node physically is. Astrology is geocentric, so the ecliptic is the apparent path of the Sun around the Earth, and it is defined as latitude zero. Planets can sit above it or below it, while the Sun always travels exactly along it. The Moon's orbit around the Earth is tilted against that path, so the two planes intersect at exactly two points. Where the Moon crosses from north of the ecliptic to the south, that crossing is the South Node. Where it crosses from south to north, that crossing is the North Node.
That geometry is also why eclipses belong to the nodes. When a New Moon or a Full Moon happens on the ecliptic or very close to it, near one of the nodes, one luminary covers the other and an eclipse occurs. The points the whole draconic zodiac is measured from are the eclipse points of the sky.
True node and mean node side by side
| True node | Mean node | |
|---|---|---|
| What it tracks | The Moon's actual orbital plane at your moment of birth | The average position, with the wobble smoothed out |
| Motion | Mostly retrograde, but it stations and turns direct a few days a month | Always retrograde, always at the same speed |
| Can it be stationary? | Yes | Never |
| Typical gap from the other | A degree or so, rarely more than two | A degree or so, rarely more than two |
| Who uses it | Us, in every chart we produce | Some other calculators, including Astro-Seek's draconic tool |
The two never stray far apart. They can still land on opposite sides of a sign boundary.
A worked example
Take a real chart that came to us through support. Calculated as a true node, its North Node falls at 24 degrees 41 minutes of Libra. Calculated as a mean node, the very same moment gives 26 degrees 00 minutes of Libra. The two disagree by 1 degree 18 minutes.
Now subtract each of those from the same tropical Sun at 24 degrees 48 minutes of Pisces.
With the true node, the draconic Sun lands at 0 degrees 06 minutes of Virgo. With the mean node, it lands at 28 degrees 48 minutes of Leo.
Same Sun, same sky, both sums correct. The Sun sits six arcminutes inside Virgo on one reading and just short of the line on the other. The sign boundary is what makes a difference of 1 degree 18 minutes look like a different chart.
And it happened to every other point in that chart at the same time, by the same amount. Lilith moved from 29 degrees 36 minutes of Libra to 0 degrees 55 minutes of Scorpio. The reader noticed her Sun and her Lilith because those two happened to be standing on thresholds. Her Mars and her Jupiter shifted by the identical 1 degree 18 minutes and she never saw it, because they had room to move.
The same choice, seen in the ephemerides
The gap shows up in mundane timing too, and María demonstrates it with a live comparison in the video, watching the node change signs in mid 2026. Measured as the mean node, the axis slipped back from Pisces into Aquarius at the end of July. Measured as the true node, the same ingress arrived in August. One axis, two calendars, days apart.
For an ordinary chart that difference is trivia. For a draconic chart it moves every planet, because the node's longitude is subtracted from every point at its exact degree. María repeats the consequence twice in that video: the choice changes the positions of the draconic planets, and it changes the calculation of the draconic chart itself.
So which node is right?
Neither, in the way the question is usually meant. This is a choice each astrologer makes, and María Blaquier is direct about it in her own draconic astrology course:
Which one is better? Well, this is up to the astrologer to decide. Personally, I tend to use the true node, but this doesn't mean that the mean node doesn't work. That's a decision for each astrologer to make.
Why María uses the true node
Her preference has a specific origin, and it is a technical one.
María works with the stationary node, a technique resting on an observation published by the American astrologer and psychiatrist Anthony Louis: when the node is stationary in a solar return, that year tends to bring significant and memorable events. Louis reported it from roughly fifty solar returns of well-known people who had a major event in the year concerned, and he is careful to present it as an observation he noticed rather than a formal study.
The technique carries a hard requirement inside it. A mean node can never be stationary, because it is an average and it always moves backward at the same fixed rate. Only a true node can come to a stop. Any astrologer who wants to read stationary nodes is therefore obliged to use the true node.
The mean node can never be stationary. Only the true node can. That is why I started using the true node.
Consistency is the part that actually matters
Whichever node an astrologer picks, the discipline is in using it everywhere.
We use the true node in every chart we produce, with no exceptions, because mixing the two is not a systematic reading. A chart built on a true node and compared against transits built on a mean node will disagree with itself by a degree, and that degree will show up as a contact that is not there or a contact that is missing.
The same applies to you as a reader. If you are going to compare charts across two sites, set both to the same node first. Otherwise you are comparing two systems and calling the difference a discrepancy.
What to do when two sites disagree
Check the node setting first. If the other site lets you choose, switch it to the true node and see whether the difference disappears. Usually it does, and that is the end of the mystery.
If the placement is within a degree of a sign boundary, read it as a threshold. Two calculations putting your Sun on either side of a cusp are telling you something real: that Sun is standing in a doorway. Neither sign is a mistake, and the placement will carry a flavour of both.
If the gap is bigger than about two degrees, the node is not your culprit. Look at the birth time and the time zone instead. An error in either moves the angles quickly and can move the Moon, and it produces differences that a node setting never could.
Will draconicchart.com support other nodes?
We have seriously considered building a tool for advanced astrologers that lets you run a chart on a node other than the true North Node. It is something we may build and publish further along.
Nothing is scheduled, so we would rather not put a date on it. If you want to hear about it if and when it exists, leave your email below and we will write to you.

Frequently asked questions
- Does this site use the true node or the mean node?
- The true node, in every chart we produce, with no exceptions. It is subtracted from every placement and every house cusp to build your draconic chart.
- Why does Astro-Seek show a different draconic chart than this site?
- Because its draconic calculator subtracts the mean node while we subtract the true node. The two nodes sit about a degree apart, and since the draconic chart subtracts that value from every point, the whole chart shifts by that degree. You only notice on placements that were already close to a sign boundary.
- How far apart are the true node and the mean node?
- Rarely more than a degree or two. They can still fall in different signs when they straddle a boundary. In May 2020, for example, the true node entered Gemini while the mean node stayed in Cancer for the rest of the month.
- Is the true node more accurate than the mean node?
- The true node is more precise, in that it reflects the Moon's actual orbital plane at your moment of birth rather than an average of it. Whether that precision makes for a better reading is a separate question, and astrologers answer it differently. Very good astrologers work with each.
- My draconic Sun changed signs between two sites. Which sign is really mine?
- Both calculations put your Sun in almost exactly the same place in the sky. It happens to be standing within a degree of a sign boundary, which is why a shift of one degree moves it across. In our readings it will be in the sign the true node gives, and it is worth reading the neighbouring sign too, since a placement that close to a cusp carries something of both.
- Will draconicchart.com let me choose a different node?
- Every chart we produce today uses the true North Node, and that is deliberate: it keeps every reading on one consistent system. We have considered a tool for advanced astrologers that would let you pick a different node, and we may build it further along, though nothing is scheduled. There is a form on this page if you want to be told when it exists.
