Here is a graph showing the amount of Earth rotation every 86,400 seconds constructed with IERS data of the last year:
The definition of a day that matters to us earthlings is the average amount of time from one solar noon to the next (or alternatively, the time it takes for the Sun to appear above the same meridian from day to day); it is called a solar day. The sidereal day, which is the time it takes for some given distant star to appear above the same meridian from day to day, is not the one that really matters to us; this is also the amount of time it takes for the Earth to rotate 360 degrees.
While the Earth is rotating on its axis, it is also travelling along its orbit. In about the amount of time it takes to complete one revolution, it has also travelled about one degree along its orbital path so that in order for the Sun to appear above the same meridian, the Earth has to rotate about 361 degrees.

What does Earth’s rotation cause us to experience?
Explain why the Sun appears to move across the sky from east to west each day.
Students recorded when the Sun rose and set over three days.
Day | Sunrise | Sunset |
|---|---|---|
Monday | 6:45 AM | 7:30 PM |
Tuesday | 6:46 AM | 7:29 PM |
Wednesday | 6:47 AM | 7:28 PM |
What pattern do you notice?
