US EditionMysterious boost to Earth's spin will make Aug. 5 one of the shortest days on record
EARTH, AUG 5 – Earth's rotation is accelerating due to factors like the moon's recession and melting ice sheets, causing three shorter days in 2025, with one 1.36 milliseconds shorter, scientists say.
- On Tuesday, Aug. 5, 2025, Earth's solar day will be 1.34 milliseconds shorter than 24 hours, making it one of the shortest days since records began.
- Amid less understood core dynamics, scientists note that the reasons for Earth's rotation speed increase in recent years are unclear, with liquid core slowdown likely involved.
- In July, scientists forecast solar days shorter than 24 hours on July 9, July 22, and Aug. 5, with Aug. 5 being the shortest at 1.36 milliseconds less.
- While imperceptible to humans, millisecond variations can affect computers, satellites and telecommunications, necessitating atomic clock tracking.
- Experts caution that a negative leap second could be added if Earth's rotation accelerations continue through 2029, with about 40% probability by 2035.

August 5 will be the third shortest day this summer — scientists worry about long-term effects: ‘Big deal’
Scientists say that Earth will spin a tad faster than usual on Tuesday — shortening the usual 24-hour day by 1.25 to 1.51 milliseconds. This prediction was made by the International Earth Rotation, Reference Systems Service and the U.S. Naval Observatory, according to TimeandDate.
