If it feels like you don’t have enough time in the day, there’s a reason for that. A scientific one, in fact.

A new study found that Earth’s rotation speed has increased quite a bit, causing a day this past June to be 1.59 milliseconds shorter than the average day, which is about 86,400 seconds. Apparently, Earth’s rotation has been speeding up since 2016, according to scientist Leonid Zotov, and shows no signs of slowing back down. In 2020, for example, scientists recorded the 28 shortest days since 1960.
