The Earth completed its shortest day on record in late June 2022 which beat the previous record set in 2020. The report was published on July 27 by the Norwegian time zone tracking website timeanddate.com. It said the Earth completed one full revolution on June 29 in 1.59 milliseconds less than 24 hours.
This counts as the shortest day since scientists began using thee atomic clock to measure the planet’s rotational speed. The times are taken from data provided by the International Earth Rotation and Reference Systems Service. The planet usually takes a couple of milliseconds or longer to complete one rotation every century.
The author of the report wrote “within this general pattern, however, the speed of Earth’s spin fluctuates, … From one day to the next, the time Earth takes to complete one rotation goes up or down by a fraction of a millisecond.”
