Earth to have 2nd-shortest day in history Jul. 22
Digest more
Earth is spinning faster this summer, making the days marginally shorter and attracting the attention of scientists and timekeepers. But these days are not ‘short’ in terms of how many sunlight hours they have — rather because they clock in at slightly less than exactly 24 hours.
On July 9, 2025, scientists at the International Earth Rotation and Reference Systems Service (IERS) reported that the Earth completed its rotation approximately 1.3 to 1.6 milliseconds faster than the standard 24-hour period. Moreover, this is expected to happen again on July 22 and August 5 this year.
Broadly speaking, Earth takes roughly 24 hours to spin around on its axis. Ocean tides, volcanic activity and earthquakes can affect rotation speed. For years, however, the Earth has been spinning faster,
Our planet is going to spin a little faster on July 9, July 22, and August 5, thanks to the moon’s distance from the equator.

The Earth's Rotation Is About to Spin Up So Much That Tomorrow Will Be Much Shorter Than Today
The Earth's rotation is about to accelerate significantly. According to scientists, July 9, July 22, and August 5 of this year will be some of the shortest days in recent memory as a result, slicing well over a millisecond off the usual 24 hours ...

Over the course of Earth’s history, its rotation has been slowing down. Some 1.4 billion years ago , a day lasted 18 hours and 41 minutes and during the Age of Dinosaurs, a day was only 23 hours.
