Just saw this on Facebook, interesting topic but I didn't take the time to "google" for verification.
"Earth is predicted to spin slightly faster on three specific days in 2025—July 9, July 22, and August 5—resulting in some of the shortest days ever recorded, according to a new report by Timeanddate.com. The difference will be subtle, measured in milliseconds, with August 5 expected to be about 1.51 milliseconds shorter than the average day.
Scientists believe this unusual acceleration may be caused by a combination of factors, including movements in Earth’s molten core, melting glaciers redistributing mass, and climate phenomena like El Niño and La Niña. Intriguingly, the Moon's position—being farthest from Earth's equator on these days—could also play a role.
Experts are puzzled by the trend, as Earth was expected to slow down over time, not speed up. This could eventually lead to an unprecedented adjustment in global timekeeping: the subtraction of a leap second by 2029. Physicists and geophysicists remain baffled by the cause, with some suspecting mysterious changes deep within Earth’s interior, as current ocean and atmospheric models fail to explain the sudden rotational boost."
