The Earth is picking up speed, and it’s forcing scientists and timekeepers to consider an unprecedented move. According to ...

Broadly speaking, Earth takes roughly 24 hours to spin around on its axis. Ocean tides, volcanic activity and earthquakes can ...

Earth is spinning faster this summer, making the days marginally shorter and attracting the attention of scientists and ...

On July 9, 2025, scientists at the International Earth Rotation and Reference Systems Service (IERS) reported that the Earth ...

The science behind why the Earth will spin just a little bit faster on July 9, July 22, and August 5, this year.

This summer a few factors are adding up to make a handful of Earth’s spins—those occurring on July 10, July 22 and August 5—more than a millisecond faster than the average of the past several decades.

July 22 will not be a normal 24-hour day. Instead, Earth's rotation will be completed just shy of those 24 hours. Find out ...

Scientists have anticipated that Earth's rotation will quicken enough to create three shorter days between July and August. The first was Wednesday, July 9, which had about a -1.30 ms "length of ...

When we measure the rotation rate of the Sun, we find that it's one of the slowest rotators in the entire Solar System, taking from 25-to-33 days to make one 360-degree rotation, dependent on ...

“Earth has recorded its shortest day since scientists began using atomic clocks to measure its rotational speed,” TimeandDate reported. “On June 29, 2022, Earth completed one spin in 1.59 ...

Each rotation takes 24 hours, or 86,400 seconds. The Earth has been experiencing many short days recently: in 2020, Earth experienced the 28 shortest days in recorded history.

The planet’s rotation was completed 1.59 milliseconds short of a 24-hour day on June 29, breaking the record for the world’s shortest day in modern history.
