For a few days this summer, your days will be just a smidge shorter
You're not running late — Earth is just moving faster, at least for a few days this summer.
On July 22, Earth will spin about 1.38 milliseconds faster than its typical 86,400 seconds in a day. If that's not quick enough, Earth will rotate 1.51 milliseconds faster on August 5.
Those numbers are calculated by the International Earth Rotation and Reference Systems Service, according to The IERS tracks Earth's orientation in space and schedules leap seconds, which are added to help keep our clocks synchronized with astronomical time (when Earth moves a bit more sluggish).
