How is the constellation calculated?

Calculate the new calendar of the year you were born! Never change! If the landlord is July 22 1990, it will always be July 22, and your constellation will not change! If you meet two constellations, it depends on when you were born, or there is another saying! For example, July 22nd is Cancer, which can also be called "Cancer Leo"! Because 7/ 19-7/25 happens to be the date they crossed! There is also this saying, the above is original for yourself, and it is by no means a transfer. Thank you. You can ask again if you don't understand the landlord!
