How to test eight characters if you don't know your real date of birth?

If you don't know your real date of birth, you can't calculate the constellation. However, there are some ways to help you guess your birthday. These methods include:

1. Understand the eight characters through family files. You can contact the elders at home and ask them if they remember your birth time. If they remember, you can use this time to calculate the eight characters. If they don't remember, you can ask other family members' horoscopes, from which you can calculate your own birthday.

2. Calculate the eight characters through the zodiac. According to your zodiac attribute, you can guess the heavenly stems and earthly branches combination of your constellation. For example, "mouse" is positive, corresponding to A, E, G, N and D in the heavenly stems. If you were born in the year of "mouse", then your heavenly stems may be A or E. In addition, the children, ugliness, yin and sea in the earthly branches also correspond to the attribute of "mouse". Together, your constellation is likely to be a combination of "Wuzi Day".

However, these methods are not as accurate as using accurate birth date to calculate astrology. Therefore, if you want to get the most accurate eight-character calculation, it is recommended to find the accurate date of birth before calculating.
