In recent years, Earth has been speeding up. In 2020, timeanddate reported that Earth had achieved its 28 shortest days since accurate daily measurements using atomic clocks began in the 1960s.
The shortest day of all in 2020 was -1.47 milliseconds on July 19.
Earth continued to spin quickly in 2021, although the shortest day of the year in 2021 was fractionally longer than in 2020.
Now, in 2022, things have speeded up again. On June 29, Earth set a new record for the shortest day of the atomic-clock era: -1.59 milliseconds.
Earth nearly beat its record again the following month, posting a length of day of -1.50 milliseconds on July 26.

And there is something called as Leap Second.
