The Northern & the Southern Celestial Hemispheres

From Aries to Libra is the Northern Celestial Hemisphere. When the Sun is in the Northern Hemisphere, days have more duration.

From Libra to Aries is the Southern Celestial Hemisphere. When the Sun is in this Hemisphere, nights have more duration.

The Great Circle called the Zodiac, " the oblique line that beareth all planets", as Dante called it, is divided into 4 quadrants of (360/4) 90 degrees.

The First 90 degrees is Odd
The Second 90 degrees is Even
The Thirdt 90 degrees is Odd
The Fourth 90 degrees is Even

"Oja yatra guanira kotir apara meshadi jookadhi kau"

The distance traversed by a planet is called Bhuja & the untraversed distance is Koti.

We give below the equation of Bhuja

In the First Quadrant, if a planet traverses 42 degrees, the bhuja is 42 degrees


In the first 90 degrees, the same longitude
In the Second 90 degrees, longitude = 180- longitude
In the Third 90 degrees, longitude = longitude - 180
In the Fourth 90 degrees, longitude = 360 - longitude

This equation of Bhuja should be applied for all astro mathematical calculations.
