Why are there different divisions about the dates of constellations?

The division of the date of the constellation itself is only a rough division of the sun constellation. On the day when two constellations meet, the sun may run to different constellations on the same day in different years. To understand astrology and get the most accurate judgment is to use astrology software to input detailed birth time and birth latitude and longitude, and draw an astrolabe to determine.

The astrolabe can include all the planets in the solar system except the earth and the moon, and other important celestial bodies related to astrological prediction and its relationship with the ecliptic. Almost all astrological judgments are obtained from the astrolabe, including your personality, fortune, spouse, work, innate and acquired factors ... all of which can be seen from it.

What we usually say is "What constellation are you?" The constellation referred to is only the sun constellation, that is, the house where the sun is located in the horoscope, as are other so-called moon constellations and Venus constellations. In astrology, every planet affects part of a person's personality.
