WebScientists monitoring the Earth's rotational speed expect the trend of having shorter days to continue through 2024. According to their calculations, an average day in 2024 will be about 0.2 ms shorter than 86,400 seconds. … Earth rotates once in about 24 hours with respect to the Sun, but once every 23 hours, 56 minutes and 4 seconds with respect to other distant stars ( see below ). Earth's rotation is slowing slightly with time; thus, a day was shorter in the past. This is due to the tidal effects the Moon has on Earth's rotation. See more Earth's rotation or Earth's spin is the rotation of planet Earth around its own axis, as well as changes in the orientation of the rotation axis in space.
