Ayanamsha
The differnce between the origin of the fixed zodiac and the tropical zodiac. Defining the zodiac is the big problem and people have tried to solve it. The sky around earth is divided into 12 equal parts. Each part is a zodiac. The earth is tilted to roughly 23 degrees, and circles around sun with the tilt pointing towards or away from sun. Earth also rotates on its own axis. The precession of the equinoxes refers to the precession of Earth's axis of rotation with respect to inertial space. As the earth precesses every year the imaginary point of begining of zoadic also slides by say roughly 50 seconds a year. This is measured with reference to some fix star. This precession of the equinoxes gives a birth to ayanamsha. It is the difference between the tropical zodiac and the nirayana zodiac. So people in the past have tried to pinpoint exact location of fixed zodiac in the past. As They haven't agreed on which it should be we have various opinions. Most widely used are Lahiri (Default) also known as chitrapaksha. According to this the fixed or sidereal zodiac starts exactly 180 degrees from chitra (the spica) star. That origin is called nirayana mesha arambha bindu.
