How often do the lunar nodes change signs?

They change signs roughly every 18 months. The nodal axis moves backward through the zodiac, and both nodes cross into a new pair of opposite signs together; identify the North Node's destination and read it with the opposing South Node.

Should I read the North Node or South Node first?

Start with the North Node as the direction to develop, then use the South Node to identify the familiar pattern that needs less emphasis. They always occupy opposite signs and should not be interpreted separately; personal effects also depend on the natal chart.

Do Vedic and Western astrology interpret the lunar nodes differently?

Yes. Vedic astrology treats Rahu and Ketu as a major karmic axis, while modern Western astrology often frames the North Node as development and the South Node as an overused habit; check which framework an interpretation is using.

Lunar Nodes Sign Ingress

Sky event · applies to everyoneSteady♈︎Western Astrology

A lunar-node sign ingress occurs when the nodal axis moves into a new pair of opposite zodiac signs, roughly once every 18 months, marking a change in collective direction. The twelve forms are organized by the North Node's destination, such as Aries, Taurus, or Gemini, with the South Node entering the opposite sign. Read each form by comparing the direction to develop with the familiar pattern to reduce.

In detail

A nodal ingress forms when the retrograding lunar-node axis crosses a zodiac boundary, placing the North and South Nodes in a new pair of opposite signs for roughly 18 months. Vedic astrology treats Rahu and Ketu as a major karmic axis, while modern Western astrology commonly reads the North Node as a direction of development and the South Node as an overfamiliar pattern. The twelve forms differ by the North Node's sign and must be read with its opposite.
