Aug. 5 might be one of the shortest days of the year: Here’s why
Scientists only on August 5 The shortest days 2025.
On Tuesday, according to a shared updated prediction, the world can rotate faster than 1.25 milliseconds. Timeanddate.com.
More than one factor can contribute to changes Rotation of the Earth Atmospheric wind currents, the position of the world seas and the position of the moon.
Jason Nordhaus, a professor of physics at the Rochester Institute of Technology in New York, says that scientists have followed and collected certain data that has been fluctuating for decades since the 1960s and the 70s.
“In the past, the world is actually much slower, perhaps three milliseconds a day.” “Then, it is constantly moving in the opposite direction, and then perhaps in five years, it really turns. It goes faster and that’s why you take the shorter days.”
Scientists say that July 22 will be the shortest period of the year
Nordhaus said the world’s rotational changes were not perceived for the human eye.
“This is not something that no one will notice, Professor said Professor. “If you wake up in the morning and look, you don’t know how milliseconds are.”

However, small changes can be taken by the atomic clock, a sensitive tool that scientists use for space navigation and GPS systems, and the changes are more pronounced over time.
“If you misunderstand and closed up to a millisecond or two milliseconds, I think it works to be such a thing, you may increase your positions to 50 centimeters 100 centimeters. And so if you accumulate for a year, you may be half a kilometer in your GPS system, Nord said Nordhaus.
Why was July 9 in the registration?
Scientists use the idea of splashing seconds to consider changes in a similar way to the concept of a leap year.
“If you look at the 70s so far, 25 or 30 jumps have been added to a second to resist all of them over time.” He said.
This summer was three more days when the Earth seems to have returned faster than normal – July 9, 10 July and 22 July – more. On July 9, the world returned to 1.23 milliseconds the next day, faster than 1.36 milliseconds, and then on July 22, about 1.34 milliseconds. Timeanddate.com.
