Calculate your North Node sign and degree
The North Node is always opposite the South Node, and it moves slowly through the zodiac. That’s why the degree can be just as important as the sign. This calculator gives you the exact degree so you can interpret your nodal axis more precisely.
How to use the North Node calculator
- Open the North Node Calculator.
- Enter your birth date and birth time (if unknown, use 12:00).
- Select the time zone offset your birth time was recorded in.
- Click Calculate to see your North Node sign and degree.
Mean node vs true node
This site uses the mean North Node, a smooth value often used in astrology software. Some astrologers use the true node (which includes short-term oscillations). If your chart settings specify “true node,” your result may differ slightly.
North Node Calculator FAQ
Do I need my birthplace to calculate my North Node?
For the North Node’s zodiac position (sign/degree), the key input is time. Birthplace is mainly needed for houses and angles (Ascendant/MC). If you want houses added, we can extend the calculator.
Is the North Node the same as Rahu? What about Ketu?
In many Vedic astrology contexts, the North Node is called Rahu and the South Node is called Ketu. They are always opposite each other in the zodiac, at the same degree.
Why does my North Node differ from another website?
Differences usually come from mean vs true node, time zone/daylight saving settings, or rounding. Make sure you’re using the same node type and the correct time zone offset for your birth time.
How often does the North Node change signs?
The North Node moves slowly and typically stays in a sign for roughly 1.5 years. Exact sign-change timing can vary slightly depending on whether you use mean node or true node.
What if I don’t know my exact birth time?
Use 12:00 (noon) as a starting point. The North Node moves relatively slowly, so the sign often stays the same, but the degree can shift.
Does daylight saving time (DST) affect the result?
Yes, it can. If your birth time was recorded in local time, you need the correct UTC offset at the moment of birth (including DST, if it was in effect). A wrong offset can shift the calculated degree.
North Node sign table (by date)
If you only need a quick answer, you can approximate your North Node sign using the table below. If your birth date falls close to a sign-change date, use the calculator with your exact birth time.
Important: This table is generated using the mean North Node (UTC noon sampling). Some sites publish tables based on the true North Node instead, which can shift the changeover slightly. For an example of a true-node table format, see Cafe Astrology’s “North Node Sign Tables” page: cafeastrology.com/northnodetables.html.
