Draconic Chart

A draconic chart is a version of your birth chart in which the zodiac is measured from the Moon’s North Node instead of the spring equinox: the node becomes 0° Aries, and every planet shifts by the same amount. This calculator works out your natal positions from your birth data, finds the lunar node, and lists both charts side by side with a printable draconic wheel.

What is a draconic chart?

In Western astrology the ordinary (tropical) zodiac starts at 0° Aries, where the Sun crosses the celestial equator in spring. A draconic chart instead starts the zodiac at the Moon’s North Node — the point where the Moon’s orbit crosses the ecliptic heading north. The node is placed at 0° Aries and every planet, angle and point moves by the same amount, so all the relationships (aspects and house placements) stay the same; only the signs change. Astrologers who use it often describe it as a chart of underlying motivation or “soul” themes.

How the calculation works

1. Convert the birth time to Universal Time using the UTC offset in force at the time.
2. Calculate the tropical longitudes of the Sun, Moon and planets, and the Ascendant and Midheaven from the birthplace.
3. Calculate the Moon’s North Node — mean (a smooth average) or true (including its wobble).
4. Subtract the node’s longitude from every point.
5. Read the new signs: the node is 0° Aries; a planet 30° past the node is at 0° Taurus, and so on.

Worked example

If the North Node at birth is at 12° Aquarius (312° of the zodiac) and the Sun is at 24° Gemini (84°), the draconic Sun is 84 − 312 = −228°, which is 132° — 12° Leo. Every other point moves back by the same 312°. Aspects don’t change: if the Sun and Moon were 90° apart in the natal chart, they are still 90° apart in the draconic chart.

Mean node or true node?

Both are used. Choose the one your astrologer or tradition uses, and note it on printed charts.

Birth data tips

• Use the exact birth time if you have it — the Moon moves about half a degree an hour, and the Ascendant about a degree every four minutes.
• Enter the UTC offset that applied at the time, including daylight saving time.
• Latitude and longitude of the birthplace matter for the Ascendant and Midheaven, not for the planets.
• If the birth time is unknown, ignore the Ascendant, MC and exact Moon degree.

Reading the table

The table lists each point’s natal (tropical) position and its draconic position. Because the shift is the same for every point, the draconic wheel looks like the natal wheel rotated. Many people compare the two — for example, noting when a draconic planet falls on a natal planet or angle.

The lunar nodes explained

The Moon’s orbit is tilted about 5° to the Sun’s apparent path (the ecliptic), so it crosses the ecliptic at two points each month. The North (ascending) Node is where the Moon crosses heading north; the South Node is exactly opposite. The nodes slowly move backwards through the zodiac, completing a full circle in about 18.6 years. Eclipses happen when a new or full moon occurs near a node — which is why the nodes were important to ancient astronomers, and the source of the old name “draconic”, from the dragon once said to swallow the Sun or Moon.

How much the chart shifts

Because the node moves about 19° a year backwards through the zodiac, the size of the draconic shift depends on your birth year. People born about 18.6 years apart have similar node positions and therefore similar draconic shifts, while people born nine years apart have nodes roughly opposite each other. The draconic shift is the same for everyone born on the same day, but the Ascendant and Midheaven still depend on the time and place.

Draconic charts and other variants

Accuracy

The calculator uses published astronomical approximations for planetary positions and the lunar node, computed in your browser. Positions are typically within a fraction of a degree for dates between about 1800 and 2050, which is sufficient for sign and approximate degree placement. For professional work, compare with an ephemeris.

A note on astrology

Astrology is a cultural and interpretive tradition, not a science; this page describes how draconic charts are calculated and used within it. The positions themselves are astronomical calculations.

Astrology printables

The optional pack includes blank chart wheels for natal and draconic charts, a comparison worksheet for natal vs draconic placements and a glyph reference sheet. The calculator above is free.
