The Earth’s rotation is faster than usual, resulting in the shortest day ever recorded. Because of this minute shift in time, we may need to consider a negative leap second. The negative leap second would be a leap second that would occur when the time difference between now and the previous leap second was less than one second. The negative leap second would occur at the end of the year. The next positive leap second would occur on June 30 or December 31.
Normally, the clock would move from 23:59:59 to 00:00:00 the next day. The International Earth Rotation and Reference System (IERS) defines the negative leap second as a leap second that occurs when the time difference between now and the previous leap second is less than one second. The IERS defines the positive leap second as a leap second that occurs when the time difference between now and the previous leap second is greater than one second.
On June 29, Earth had its shortest day ever—1.59 milliseconds shorter than 24 hours. The “Chandler Wobble” might explain the apparent acceleration of Earth’s rotation.
This minute shift in time may necessitate the use of a negative leap second. The International Earth Rotation and Reference Systems Service (IERS) is considering a change to the time of day that would eliminate the need for a leap second. The IERS is currently in the process of developing a new leap second algorithm to replace the current one. The new algorithm would be based on the Chandler Wobble. The IERS will present a proposal to the International Bureau of Weights and Measures (BIPM) on September 26, 2022.

resulting in the shortest day
If it appears like the world is moving quickly, it is the rotation of the earth.
Q&A
which way does the earth rotate?
According to NASA, its rotation orientation is prograde, or west to east, which looks counterclockwise when viewed from above the North Pole, and it is shared by all planets in our solar system except Venus and Uranus.
Why is Earth spinning faster?
The source of the Earth’s varying rotation speed is yet unclear. Scientists suggest that this might be due to activities in the core’s inner or outer layers, seas, tides, or even climate change.
how fast does the earth spin
The earth spins once every 23 hours, 56 minutes, and 4.09053 seconds, and its diameter is approximately 40,075 kilometers. Thus, near the equator, the earth’s surface rotates at a rate of 460 meters per second, or around 1,000 miles per hour.
what is revolution of the earth
The Earth rotates around the sun in 365 days, 6 hours, and 9 minutes, according to the stars, at speeds varying from 29.29 to 30.29 km/s. Every fourth year, which is classified as a leap year, the 6 hours, 9 minutes add up to nearly an extra day, with the extra day added as February 29th.
