English: Graph showing the equation of time (red solid line) along with its two main components plotted separately:
The part due to the obliquity of the ecliptic (mauve dashed line), i.e. the equation of time without the ecliptic; and
The part due to the Sun's varying apparent speed along the ecliptic due to the eccentricity of the Earth's orbit (dark blue dash & dot line), i.e. as if the earth was turning around the sun on a circle.
