Question 3:1Is the fixed time in 24 solar terms solar or lunar? Which timing is better, the solar calendar or the lunar calendar?

To say these things is related to the calendar. To explain these problems, we must first understand these three problems. What is the solar calendar? What is the lunar calendar? How are solar terms divided? Let me give you a brief introduction. What is the solar calendar? The solar calendar is the solar calendar, and Yang is the sun. According to the time of the earth's revolution around the sun is 1 year, but our solar calendar has 365 days and 366 days, both of which are about 1 365.24 days. In days, it is divided into 12 months according to the obvious changes of the four seasons. What is the lunar calendar? The lunar calendar is actually called the lunar calendar, which is the lunar calendar. The lunar calendar is based on the moon. Every month, both chords are fixed. It's a month, every month or 29 days, or 30 days, about 29.53 days. It is also in days. So a year in the lunar calendar is 12 months, just like the sun. In order to make every year as close as possible to the return cycle of the sun, the lunar calendar uses the moon as an ornament, which is usually said, a little ornament in three years, a big ornament in five years, and a * * * ornament in nineteen years. Because the solar calendar does not consider the lunar calendar, every month in the solar calendar cannot correspond to the moon phase change. For example, 15 full moon, solar calendar number 15 can't. The third question, how are the solar terms divided? Solar terms are divided into two points or two points according to perihelion and apohelion. Therefore, solar terms are actually 24 points divided by the earth relative to the sun. So the time of solar terms is closer to the solar calendar, but it is not fixed. Generally, it changes within 2 or 3 days. Because the solar calendar is also approximately divided, it can only fluctuate around a certain day. Now, can you answer all three questions you asked? The first problem is that solar terms are closer to the time division of the solar calendar. The second question is that the calendar making methods of solar calendar and lunar calendar are different. No one is better. You can use any calendar you need. Third, the lunar calendar is mostly a calendar made in ancient times to meet the needs of farming, which has been circulated for thousands of years.
