Every six years, Earth spins slightly faster and then slower. Cyclic changes in day length overlie decades-long trends. The world turns slightly faster and slower on a regular 5.9-year cycle, a new study suggests.

The Earth rotates once in about 24 hours with respect to the sun and once every 23 hours 56 minutes and 4 seconds with respect to the stars (see below). Earth's rotation is slowing slightly with time; thus, a day was shorter in the past.he Earth rotates once in about 24 hours with respect to the sun and once every 23 hours 56 minutes and 4 seconds with respect to the stars (see below).
