As Earth spins faster than it has in decades, atomic clocks are catching the difference, and shorter days are on the horizon.

As for when this three-day event will happen, there are three days this summer when the moon will be around its furthest distance from Earth’s equator, resulting in the slight increase in Earth’s rotational speed. Scientists are predicting that this will happen on July 9, July 22 and Aug. 5.

Scientists anticipate that Earth's rotation will quicken enough to create three shorter days between July and August, starting Wednesday, July 9.
