What is a second (sidereal)?

A sidereal second is the time unit defined as 1/86,400 of a sidereal day, which tracks Earth's rotation relative to fixed stars rather than the Sun.

Why convert sidereal seconds to months?

This conversion helps relate precise astronomical time, based on Earth's star-relative rotation, to familiar calendar periods for easier interpretation of observational data.

Is the conversion exact?

No, since months vary in length and sidereal seconds differ slightly from standard seconds, the conversion provides an approximate equivalent.
