Is a day 12 hours or 24 hours?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.

25 hours?In the usual time measurement system, a day was divided into 24 hours. This was a standard time measurement method that was man-made based on the Earth's rotation period.
However, from the perspective of special circumstances or relativity," 25 hours " could exist in the concept. For example, during long-distance travel across time zones, one's biological clock might be disrupted. A person might feel that the time of the day was like 25 hours. This was a subjective experience based on physiological and psychological feelings. Or, under some scientific assumptions, sci-fi scenarios, and philosophical considerations of time relativity, the concept of " 25 hours " could also be proposed, but this was not the concept of the standard time measurement system in the traditional sense.
