Equinoxes do not occur on the same date each year because of the following reason: Statement 1: Difference of 6 hours in revolution time. (365¼ days) Statement 2: Difference of 5 hours in rotation time. (24 1/5 days) Statement 3: Change of seasons Statement 4: Differential heating of different places across the world.

A year is the amount of time it takes a planet to orbit its star one time. ... It takes Earth approximately 365 days and 6 hours to orbit the Sun. It takes Earth approximately 24 hours — 1 day — to rotate on its axis.
Since the Sun's motion differs from the stars' motion by one degree, and it takes 4 minutes for the Earth to turn through one degree, it takes the Sun 4 minutes longer to go around the sky than it takes for the stars to do so, and the rotation period of Seasonal Changes
Our year is divided up into four seasons: summer, fall, winter, spring. Unless someone lives at the equator, each season delivers different weather patterns. Generally, it's warmer in spring and summer, and cooler in autumn and winter.he Earth is 4 minutes less than the length of its day.
Differential heating- differences in the amount of heat received when different surfaces are heated by the sun. ... Example: snow will heat less than soil b) The sun's energy is spread out over a large area, so it heats the Earth's surface unevenly.
