Did you feel it? Earth just had one of its shortest days ever and 2 more are coming

Graphic showing a rotating Earth and a vector of a speedometer showing maximum speed.

On July 9, 2025, Earth spun a little faster than usual, enough to make the day about 1.3 to 1.6 milliseconds shorter than the standard 24 hours.

That may not sound like much, but it was the shortest day since modern records began.
