To express a hypothesis (which is the opposite of the current reality), one could say,"If there were 48 hours in a day"; or "If there were forty-eight hours in a day"; or "If only there were forty-eight hours a day" or "We often say,'I wish there were 48 hours in the day'".
The so-called day was 24 hours, which was the time it took for the Earth to rotate once. It was also calculated according to the sun's day. It was one day when the Earth rotated to the same position as the sun. However, in terms of the exact length of the Earth's rotation, its cycle was about 23 hours and 56 minutes. At the same time, under different circumstances, the length of sunlight in a day would be different. For example, during the winter solstice, there would be about ten hours of sunlight during the day, and during the summer solstice, there would be about sixteen hours of sunlight during the day. In addition, in some specific concepts, such as the time-limited eating method of intermittent fasting, the time of eating in a day would be limited to a few hours, and the rest of the time would be fasting. However, this did not change the basic definition of 24 hours a day.
In terms of health and work efficiency, it was relatively better to work eight hours a day. Since May 1, 1995, China has implemented a work system of 8 hours a day and 40 hours a week (except for some enterprises that cannot implement the standard work system due to the nature of work and production characteristics). Studies have shown that workers who work more than 60 hours a week have a 23% increase in the risk of work-related injuries and occupational diseases. If they work more than 50 hours a week, they may suffer from chronic diseases such as cardiovascular diseases. Long working hours will also lead to increased occupational stress, decreased job satisfaction, and increased risk of mental illness. However, different countries and different industries have different situations. For example, the average working hours of Japanese workers are longer, and there is a "Karoshi" phenomenon in the corporate work culture (Overwork leads to stroke, heart disease, and suicide). However, this also shows that long working hours are not conducive to health and work continuity, and the eight-hour workday system is relatively good at balancing work and health.

Since I don't have any more background information, I'm not sure what specific questions you want to ask about the two of them taking turns to work 24 hours a day. For example, the rationality of this shift arrangement, the possible salary calculation, the relevant legal provisions, or other questions? If it was about salary calculation, the normal working days would be calculated according to the salary agreed in the labor contract; if the overtime could not be arranged on the rest day, the salary would be paid no less than 200% of the salary; if the overtime was on the legal holiday, the salary would be paid no less than 300% of the salary. If it involved the calculation of seniority and other aspects, more specific information was needed to answer. The novel " Yan Xiaoqi's Journey to the Other World " is equally exciting.

According to news from the entertainment industry, in 2023, more than 60% of A-list celebrities worked an average of more than 16 hours a day. There were also actors who said that they basically worked more than ten hours a day, and there were also actors who worked 18 hours a day. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Currently, the length of a day on Earth was about 24 hours (23 hours, 56 minutes, and 4 seconds to be precise). Although the length of a day on Earth had changed in history, and due to tidal forces, it was still slowly increasing at a rate of about 1.7 ms per century, it had not yet reached 25 hours.
According to the current international time measurement standard, a day was 24 hours. However, from a scientific point of view, the Earth's rotation speed was changing extremely slowly, which might cause the length of a day to change after a long geological period. However, under the current normal time system, a day was 24 hours, not 25 hours.
In the natural state of Earth, a day was currently about 24 hours. However, judging from Earth's historical development, the length of a day was not fixed. About 4.5 billion years ago, when the Moon was first formed, a day on Earth was less than 10 hours long. Later, as the tidal force of the Moon gradually slowed down the Earth's rotation, a day became longer and longer. However, between 2.2 billion years ago and 600 million years ago, due to the mutual offset of several tidal forces, the Earth rotated at the same speed for more than 1 billion years, keeping the length of a day constant at about 19.5 hours. Even today, this tidal force continues to extend the length of a day at a rate of about 1.7 milliseconds per century. However, there were no natural factors that made a day 48 hours long. If there were to be a 48-hour day, it might be necessary to assume that there was a huge external force to greatly slow down the Earth's rotation speed or make a science fiction setting, but such a situation did not exist in reality.
