Everyone knows that a day is 24 hours, i.e., the Earth rotates around itself. Meanwhile, researchers have said that today, i.e., on august 5, the Earth's rotation is very fast. Why is this happening? What are the consequences of this? Let's take a detailed look at the background to this. While various changes are continuously taking place on the Earth, researchers are closely observing it. Meanwhile, researchers say that the Earth is spinning a little faster today. Even if we don't realize it, TimeandDate says that today, august 5, may be one of the shortest days in history. Researchers indicate that the rotation speed of our planet is increasing today. Researchers have discovered that the Earth's rotation has been gradually increasing in speed since 2020. Its speed increased further today. Researchers say that this will be one of the shortest days recorded in recent years.. Earlier on July 9, we lost 1.3 milliseconds on that day due to the increase in the speed of the Earth's rotation. Similarly, on July 22, we lost 1.4 milliseconds. That is, a day was reduced from 24 hours because the Earth's rotation speed increased on that day. Today, with the Earth rotating even faster, it seems that we will lose more milliseconds than this. We know that this is very little. None of us would have even realized this. However, researchers say that the increase in the speed of the Earth's rotation will increase further in the coming years and will cause various changes on the Earth.
If the Earth's rotation speed continues to increase, there may be problems in keeping track of time. This could lead to the need to add a negative leap second to ensure that atomic clocks are accurate. That is, we may have to add a second to our clocks that is not exactly in sync with the Earth's rotation.

What's the problem?
You might think that adding milliseconds would be easy. But it's a very complicated matter. Researchers say that making that change in clocks around the world, including computers, is not that easy. Furthermore, the exact reasons why the Earth is spinning faster have not yet been discovered. However, experts believe that changes in the Earth's inner core, atmospheric circulation, melting glaciers, and mass changes caused by El Niño and La Niño events may be the reasons. It is not only the Earth. The moon may also be a reason for this. Experts say that during the shortest days recorded in 2025, the moon was at its maximum distance from the Earth's equator, and this could also be a reason.

In this regard, Leonid Zodov, an expert at moscow State University, said, "Nobody expected this. The exact reason for this increase in speed is not known. At the same time, most researchers believe that the reason for this is the change that took place inside the Earth. However, the real reason for this is not known."
