What the nodes are

The nodes are the two points where the Moon's path crosses the Sun's. They sit exactly opposite each other, so a north node in one sign always comes with a south node in the opposite sign. They move backward through the zodiac and take about 18.6 years to go all the way around, which is roughly a year and a half in each sign, so people born close together share them.

Read them as an axis

The south node is your familiar territory: tendencies that come easily and can turn into a rut. The north node is a less comfortable direction to grow toward. With the north node in Aries and the south node in Libra, the familiar move is going along with the room, and the growth is saying what you want first. Pick one small north node move this week and see how it feels.

Questions

Do I need my birth time?

The nodes move slowly, so your birth date is almost always enough. If they changed signs on your birthday, you'll see both and be asked for a time.

Is the south node a bad placement?

No. It's the familiar side of the axis, strengths included. The risk is getting stuck there, and the north node is the counterweight.

Why does another app show a different node?

This tool uses the true node. Some apps show the mean node, which is usually close but can land in a different sign for a birth near a sign change.
