Earth to Spin Faster on July 22 to Make It One of the Shortest Days in Recorded History
Jul 22, 2025 - 10:00

On Tuesday, July 22, 2025, Earth will complete its rotation 1.34 milliseconds faster than the usual 24 hours, scientists say. That will make it the second-shortest day ever recorded, just behind July 10, 2025. The trend of shorter days has accelerated since 2020, attributed to factors like the Moon’s position, mass shifts from melting ice, and atmospheric changes.
