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.

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

Earth is expected to spin faster than usual in the upcoming weeks, leading to slightly shorter days, scientists report, according to Live Science. On July 9, July 22, and August 5, 2025, the position of the moon will influence Earth's rotation, making each day between 1.3 and 1.51 milliseconds shorter than the standard 24 hours.
