Earth's Rotation Speeds Up, Shortening Days in 2025
5 Aug
Summary
- NASA partners with Netflix to stream live space events
- August 5, 2025, predicted to be 1.34 milliseconds shorter than 24 hours
- Variations in Earth's core and atmosphere impact atomic clocks

As the world prepares for August 5, 2025, scientists are predicting that it will be one of the shortest days of the year, approximately 1.34 milliseconds shorter than the standard 24-hour period. This phenomenon is attributed to changes in the Earth's core and atmospheric influences, which can impact atomic clocks and systems reliant on precise timekeeping.
While these millisecond variations may go unnoticed by the average person, they can have significant implications for scientific and technological applications. To keep the public engaged with the wonders of space, NASA has partnered with Netflix to stream live events such as rocket launches, spacewalks, and breathtaking views from the International Space Station.
As the Earth's rotation continues to fluctuate, scientists will closely monitor these changes and their impact on global timekeeping. The ability to accurately measure and predict these variations is crucial for maintaining the synchronization of critical systems and networks that rely on precise time measurements.
