From the Chinese point of view, the significance of the lunar calendar goes far beyond this. Birthday is the so-called birthday in China tradition, which includes four parts: year, month, day and time. Each part is expressed by the method of keeping time, so each part has two characters, which is the so-called birthday, and the meaning and use of birthday in ancient times are even greater.
Even from the eight characters, you can know that your life is full of luck, good luck and bad luck, and there is a sense of mystery and mystery, so it is more in line with the habit of China people talking about lunar birthdays. For thousands of years, people in China have celebrated their birthdays in the lunar calendar, but it is only a few years since they celebrated their birthdays in the solar calendar.
