US EditionEarth to Record 1.3ms-Shorter Day Tomorrow After Unexplained Spin-Up
EARTH, JUL 14 – Earth will experience days up to 1.51 milliseconds shorter this summer due to faster rotation influenced by the Moon and complex geophysical factors, scientists say.
- On July 5, 2024, Earth completed a full rotation in 1.66 milliseconds less than the usual 24-hour period, setting a new record for the shortest day ever measured.
- This speed-up follows a trend starting in 2020, though scientists remain uncertain about the internal causes of Earth's accelerating spin.
- Seasonal changes move Earth's mass away from its spin axis in northern summer, slowing rotation, while the moon's varying distance affects daily spin length.
- Leap seconds have been periodically added since 1972 to align atomic clocks with Earth's time, but none have been added since 2016 despite these changes.
- The unusual acceleration challenges precise timekeeping and industries like telecommunications and finance, implying potential future disruptions if spin speed rises.

During this summer, on July 9, July 22 and August 5 to be exact, the days will not last the standard 86,400 seconds. Namely, the Earth will certainly - and so far inexplicably - speed up its rotation, shortening the duration of the day not by the usual 1.3, but by as much as 1.5 milliseconds.
Miami, Jul 12 (EFE).- The current summer of the northern hemisphere has some of the shortest days in history due to the acceleration of the rotation of the world, according to data from the International Earth Rotation and Reference Systems Service (IERS) and the United States Naval Observatory. On July 9 and July 10 they were some of the shortest days since registration because they lasted an estimated 1.23 and 1.36 milliseconds less than the o…
Earth's rotation could speed up. If the planet were to spin faster, not only time but also the order of the world could be disrupted.
