What is the complete spin of the earth that takes 24 hours?

Answer 1

The earth spin around its axis in almost 24 hours.

Consider for sake of argument that an invisible line is drawn through the earth vertical from the south pole to the north pole (like a top). The earth spin around this line approximately once every 24 hours.

This axis is, however, really not vertical from the north to the south pole. Instead this axis is tilted 23.5 degrees.

Answer 2

The Earth completes one full rotation on its axis every 24 hours, which is what creates the cycle of day and night. This rotation is equivalent to 360 degrees.
