0° in astrology
Understand 0 degrees as the start of a zodiac sign, distinguish rounding from an actual ingress, and check a birth chart near a boundary.
Read the guide ↗THE SKY DEGREES REFERENCE
Read the degree before the meaning.
A degree locates a point on the 360-degree zodiac circle. Each sign occupies 30°, each degree contains 60 arcminutes, and each arcminute 60 arcseconds. Convert a longitude below, then explore how different traditions add meaning to the measurement.
COORDINATE TOOL
Longitude → sign & degree
Use longitude in your chosen zodiac. This tool does not convert tropical to sidereal coordinates.
Gemini
14° 15′ 0.00″
Decan 2 · 14.250000° within the sign
Seconds are truncated to preserve the side of a boundary. The default 74.25° is a worked arithmetic example.
29° and the anaretic degree
Read the final degree of a zodiac sign accurately. Learn what anaretic means in modern astrology and why 29° does not guarantee a crisis.
Read the guide ↗Decans: three parts of a sign
Find a placement’s decan from its exact degree, understand the 10° and 20° boundaries, and separate different decan-ruler traditions.
Read the guide ↗Bounds and terms
Understand traditional bounds as unequal sign divisions, why Egyptian and Ptolemaic tables differ, and how to check a degree near a boundary.
Read the guide ↗What degree theory adds—and assumes
Separate a measured zodiac longitude from modern degree symbolism, decans and bounds. Use a reproducible checklist when comparing interpretations.
Read the guide ↗The twelve 30-degree intervals
The same intervals are used within a chosen zodiac. Tropical and sidereal systems select different reference origins; the converter does not choose an ayanamsa for you.
| Sign | Longitude |
|---|---|
| Aries | 0° ≤ longitude < 30° |
| Taurus | 30° ≤ longitude < 60° |
| Gemini | 60° ≤ longitude < 90° |
| Cancer | 90° ≤ longitude < 120° |
| Leo | 120° ≤ longitude < 150° |
| Virgo | 150° ≤ longitude < 180° |
| Libra | 180° ≤ longitude < 210° |
| Scorpio | 210° ≤ longitude < 240° |
| Sagittarius | 240° ≤ longitude < 270° |
| Capricorn | 270° ≤ longitude < 300° |
| Aquarius | 300° ≤ longitude < 330° |
| Pisces | 330° ≤ longitude < 360° |
Keep the setting with the result.
Record the birth time, location, zodiac and house system when you compare charts. A changed sign label or house placement can reflect a changed convention. If the recorded time is unknown, an exact Ascendant or house cannot be recovered by guessing.
