The Brief July 9 is expected to be one of the shortest days in history, but you won’t notice a difference. The Earth has been moving faster in recent years, and scientists aren’t exactly sure why.

Before 2020, the shortest length of day variation measured by an atomic clock was -1.05 milliseconds – meaning the Earth rotated 1.05 milliseconds faster than 86,400 seconds.
