Shorter days ahead? Why Earth might spin faster on 3 days in July and August

Earth is expected to spin slightly faster on three specific days in July and August: July 9, July 22 and August 5. This could lead to slightly shorter days. On those dates, the length of a day may reduce by 1.30, 1.38 and 1.51 milliseconds, respectively. Scientists have observed that since 2020, Earth has been rotating a little faster than usual, though the exact cause remains a mystery
