still a long day

According to the information provided, there were activities or ideas related to " daily improvement " in 2024. For example, there were companies with the corporate culture concept of "daily improvement", as well as the 2024 daily improvement·Yunnan Luoping Ninth Flower Sea Mountain Cycling Race, etc. Therefore, there were things related to "daily improvement" in 2024. While waiting for the anime, you can also click on the link below to read the classic original work of " Full-time Expert "!

The time it took for the earth to rotate once was defined as a day. To be precise, it was not 24 hours, but 23 hours, 56 minutes, and 4 seconds. From a historical perspective, when the moon was formed about 4.5 billion years ago, the length of a day on Earth was less than 10 hours; between 2.2 billion years ago and 600 million years ago, the length of a day was constant at about 19.5 hours; during the Jurassic period, the length of a day was about 23 hours and 10 - 20 minutes. As the Moon's tidal force gradually slowed down the Earth's rotation, and although the Sun also produced tidal force (including the force to slow down the Earth's rotation and the force to accelerate the Earth's rotation, the overall effect of the Moon's tidal force was greater), the Earth's rotation was getting slower and slower, and the length of the day was getting longer. Now, it was changing in an extremely small range, with an average length of 0.002 seconds per 100 years. There was also a significant increase in the amplitude of the change in the length of the day with a period of about 8.6 years. Therefore, strictly speaking, there were less than 24 hours in a day, and the length of the day was dynamic.

The time it took for the Earth to rotate once was defined as a day. To be precise, its duration was 23 hours, 56 minutes, and 4 seconds. However, in daily life, for the sake of convenience, a day was defined as 24 hours. From a historical point of view, the length of a day on Earth was not fixed. About 4.5 billion years ago, the length of a day on Earth was less than 10 hours. Between 2.2 billion years and 600 million years ago, the length of a day was constant at about 19.5 hours. During the Jurassic period, the length of a day was about 23 hours and 10 - 20 minutes. Moreover, due to the tidal effect of the Moon and the Sun on the Earth, the Earth's rotation became slower and slower. The length of the day was gradually increasing, with an average of 0.002 seconds every 100 years. In addition, Chinese researchers also found that there was a significant amplitude enhancement signal with a period of about 8.6 years. Therefore, strictly speaking, a day was not exactly 24 hours, and its length was constantly changing.

On a large time scale, due to the tidal effects of the moon and the sun on the Earth, the Earth's rotation was getting slower and slower. The length of the day was gradually getting longer, with an average of 0.002 seconds per 100 years. Therefore, strictly speaking, a day was not 24 hours, and its length was dynamic.

Vast Night and Long Night were both words used to describe the dark night. Vast Night and Endless Night both meant that the night was long and boundless. To put it more specifically, Vast Night described the night as boundless, while Endless Night referred to the endless night. These two words were very similar in meaning. They were both used to describe the endless and long night.
