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.

Most people think a day on Earth is just the time it takes for the planet to make one full rotation on its axis, but that’s not entirely true. In this video, we uncover the surprising truth about Earth’s rotation and explain why a single 360-degree spin isn’t enough to complete a full day.
