Did you hear that the Earth is moving slightly faster than normal on 5 August 2025 today? It can be surprising to hear this, because we do not see its effect in our life every day. But scientists have told that the rotation speed of the Earth is changing, due to which the days are getting a little smaller. Come, let’s understand what is all this? Why is it happening? What can it affect our life?
1. Is the earth really moving fast on 5 August?
Yes, according to scientists, on 5 August 2025, the Earth is moving slightly faster than normal. The rotation speed of the Earth has increased for the last few years. This effect is clearly visible on special dates. According to data from the International Earth Rotation and Reference Systems Service (IERS), the day of August 5 can be smaller from 24 hours to 1.25 to 1.5 milliseconds. This is a very small difference, which does not appear in our watches, but technically matters. Earlier, on 9 July 2025, the shortest day was recorded, which was 1.6 milliseconds.

2. Why is the earth moving faster than normal?
There can be many reasons for the Earth’s fast rotation. Scientists are doing research on them right now. Some of the main reasons are …
- Moon effect: The gravity of the moon slows down the earth. But when it is away from the equator of the Earth in its orbit, the speed of the Earth increases slightly. This situation of the moon is likely to happen on August 5.
- Climate change: Melting of glaciers and increasing sea levels is affecting the mass of the Earth. When the ice melts into the sea, the size of the earth changes slightly, which can increase the rotation speed. According to scientists, it is like an ice skater, which pulls the hand inside and rotates fast.
- Earthquake and Geological Activities: Large earthquakes can affect the core of the Earth, which changes the rotation.
- Magnetic field: Activities in the inner part of the Earth can also affect its speed.
Scientists say that the earth’s speed has increased since 2020. This can be the fastest speed in the last 50 years. However, it is not completely clear yet whether the same reason is responsible or many things together are affecting them.

3. How fast is the Earth revolving on 5 August?
On 5 August 2025, the Earth’s rotation speed will be slightly faster than normal, but this difference is very subtle. A normal day is 86,400 seconds (24 hours), but on this day it can be reduced by 1.25 to 1.5 milliseconds. That is, the day will be about 86,398.5 seconds.
The Earth rotates on its axis at a speed of about 1,670 kilometers per hour. Due to this change, this speed can increase slightly to around 1,670.002 kilometers per hour. This increase is so small that it cannot be felt with naked eyes, but it can be measured with nuclear watches.

4. Has the fastest speed of the Earth ever recorded?
Yes, the record of Earth’s fastest rotation speed was made on 5 July 2024, when one day was 1.66 millisecinds. Earlier in 2022 and 2021 also, 1.59 and 1.47 milliseconds were reduced. Scientists say that 1 to 2 billion years ago, the Earth day was only 19 hours, because the moon was very close at that time. His gravity used to affect more. In comparison to today, that time is considered to be the fastest rotation period in the Earth. But the record of 2024 is the smallest day in modern times.
Other questions that are necessary
1. What is a leap second and is it related to it?
The leap second is an additional second, which is added or reduced to correct time. When the Earth rotates slow, the leap second has been added 27 times since 1972, so that the time of atomic watches match the rotation of the Earth. But now the earth is moving fast, so for the first time in 2029, there is talk of “Negative Leap Second”, that is, a second. This change may be necessary for technical systems such as GPS and satellites.
2. What is the opinion of NASA or other space agencies?
NASA and other space agencies are monitoring this change. He says that the change in the speed of the Earth is normal and may be associated with the moon, climate change and geological activities. This will not affect our everyday life, but adjustment may be necessary for the technical system. They are doing accurate monitoring of this so that the right steps can be taken in the future.
