Why is the horoscope of a day inaccurate?

You mean that the lunar calendar in different years is the same day, because the constellation is based on the solar calendar, which is the constellation of people on the day of the solar calendar in the year of birth. For example, a person was born on June 65438+1 October1in Gregorian calendar (i.e. Gregorian calendar), and the lunar calendar (i.e. lunar calendar) was 099 1 1 25th, and the constellation is subject to Gregorian calendar. But by the 25th of the following year 1 1 month (that is, the 2000 lunar calendar), the solar calendar is 65438+February 20th, 2000, which is not within the range of Capricorn, so what you said is not really accurate. Constellation is western divination, and western Renye Fang is not only the lunar calendar of China, so there is only the solar calendar (Gregorian calendar).
