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.

Scientists anticipate that Earth's rotation will quicken enough to create three shorter days between July and August, starting Wednesday, July 9.

This is an unprecedented situation and a big deal,” said Duncan Agnew, a geophysicist at the University of California, San Diego.
