A day refers to a cycle in time, usually the period of time on Earth that passes from one noon to another. The length of this day, which varies depending on the position of the sun, is called a solar day, and averages 24 hours of clock time. However, the rotation of the Earth varies, for example, because the Earth's orbit is elliptical, the rotation speed will be slightly slower when it is far away from the Sun, and it will be slightly faster when it is close to the Sun.

As a result, the length of each day of the Earth is actually different, and this change is called "the equation of time".

In the course of the development of human civilization, people divided the day into different regimental time periods, usually 24 hours or 12 hours. The starting point of the day is usually the time when people finish sleeping and start working, studying and living, that is, in the early morning. People do all sorts of things during the day, including work, study, rest, play, and so on.

In different cultures and regions, people understand and utilize the day differently. For example, in Islamic society, the day is divided into five periods, each of which has a specific religious ritual, starting at sunrise and ending at sunset. In traditional Chinese culture, the day is divided into 12 hours, each of which has a specific name, such as Zi Shi, Chou Shi, and so on.

In addition to the rotation of the Earth, a day can also refer to the length of some other cyclical events. For example, some people use the term "healthy day" to describe a healthy lifestyle that includes a balanced diet, adequate sleep, and proper exercise. Some people use the term "successful day" to describe a day when some important tasks are completed or some progress is made. A day may have different meanings and values for different people, but no matter what, each of us should cherish every day we have and take seriously every opportunity that each day brings.

Some people want to live in a complex environment, and naturally some people want to live in simplicity. I belong to the latter group. Some people will ask, do you really live a simple life?

My answer is no. Maybe it's just wishful thinking, maybe it's my dream, or maybe it's a dream I had as a child. People always have to grow up, and when they grow up, they have to go through complex relationships, whether you want to accept it or not, life will only force you to recognize the reality and recognize everything that is chaotic around you.

I've always had a dream of constantly bringing myself closer to a child's mindset, naïve but unpretentious, with the maturity and insight that an adult should have. I want to live in simplicity every day.

What exactly does a simple day take? It's sitting stupidly on the steps, looking up at the sky, and posing as a thinker; After the bureau regrets, I still get up early, eat breakfast, read, study, eat lunch, take a nap, read, study, eat dinner, and sleep. Since you want to live, you need a heart to live, and simplicity means a simple heart.

There are no excessive demands, no complaints and blames, no open disputes and secret fights, only calmly treat all the past that has happened, do not indulge in the vanity and prosperity of the past, and be a good person who keeps to himself. Simplicity also means getting closer and closer to the most profound level of life, which has nothing to do with birth, old age, sickness and death, but only about the brilliance of life blooming in the journey of life.

I want to live a simple life, even if it's enough for one day. I don't like the complexity of Tongqin's things, but in fact, I sometimes have to face those complicated lives, and have to deal with all kinds of complicated events, so that I have an unrealistic fantasy of wanting to escape from reality and hide in dreams. Life is sometimes so simple, yet so complicated, that you can't figure it out.

Summary. Hello, one rotation of the earth is one day.

What is the concept of a day.

Hello, one rotation of the earth is one day.

The time of the Earth's rotation based on a distant star is called a "day", or "sidereal day".

Since daily life is greatly affected by sunlight, the 24-hour day is notated, known as the "solar day" (with the sun as a reference). One day (1) day and night (2) twenty-four hours.

That's a good question. I used to think about it, too.

One rotation of the earth is counted as one day, so how can we tell that the earth rotates in one circle? I remember this method is the time of the Earth's rotation based on a distant star as a reference, which is called a "day", that is, a "sidereal day".

Since our daily life is greatly affected by the sun, we also collect liquid wax and use the notation of 24 hours a day, that is, "the day of the sun" (with the sun as a reference).

So what you said about the two rounds of rolling is correct, but one is for science, and the other is for life.

Note: The gap between the two is exactly why you want to know.

As for the leap year problem, which some people upstairs say, it is a different problem (involving the error of one revolution), and it has nothing to do with it.

A day is a day and a night. To be exact, it is a total of 24 hours in one day and one night.
