Aug 5 set to be one of year's shortest days — by 1.34 milliseconds
UNITED STATES, AUG 5 – August 5, 2025, will be 1.34 milliseconds shorter due to Earth's accelerating rotation influenced by its core, atmosphere, oceans, and the Moon's weakening gravity, scientists say.
- On August 5, 2025, Earth's solar day will be 1.25 milliseconds shorter than the standard 24 hours, marking one of the shortest days recorded since tracking began.
- Similar shortened days occurred on July 9 and July 22, 2025, with each day falling short of 86,400 seconds.
- Scientific agencies, including the International Earth Rotation and Reference Systems Service , monitor these changes closely as they may require adjustments to global time standards.
- Scientists are monitoring Earth's rotation closely as it has accelerated recently, raising concerns about potential long-term implications for the planet's environment.

This Tuesday, August 5, the Earth will turn faster than normal, shortening the duration of the day by 1.25 millisecond. Although imperceptible for daily activities, this change in the rotation of the planet has generated concern in the scientific community. Astronomers explain that the Earth's rotation is not constant.A full day does not always amount to 24 exact hours.The duration may vary due to the gravitational influence of celestial bodies,…
Tuesday might be shorter than 24 hours, according to scientists
(CNN, KYMA/KECY) - No one will even notice, but Tuesday is predicted to be slightly less than 24 hours, by more than one millisecond. Scientists say the reason is Earth is spinning faster, likely due to changes in the Earth's liquid core and atmospheric influences. Shorter days have occurred a few times this year already. The shortest day of this year, so far, was July 10. The shortest day ever was July 5 of last year by 1.66 milliseconds. The d…
Today Will Be One Of The Shortest Days On Record And Scientists Don't Know Why
As of August 5, 2025, Earth will experience one of the shortest days on record—by just over a millisecond. This unexpected increase in rotational speed has puzzled scientists and may force changes in how we keep time in the future. Key Facts: On August 5, 2025, Earth’s solar day will be 1.25 milliseconds shorter than the standard 24 hours. Similar shortened days occurred on July 9 and July 22, 2025. The shortest recorded day was July 5, 2024, a…
Why on Earth is the planet’s day getting shorter?
Quality Stock Arts/ShutterstockEarth will complete a rotation 1.33 milliseconds earlier than usual on Tuesday, August 5. That makes it one of the shortest days of 2025 at 86,399.99867 seconds long. How that happens, and how we can even measure it with such precision, might make your head spin faster too. On average, Earth physically rotates in 23 hours, 56 minutes, 4 seconds and 90.5 milliseconds – this is called a sidereal day. It is Earth’s “t…
