If you are Gregorian calendar 4.23, you are Taurus (4.12 ~ 5.21).
If it is the 4th and 23rd day of the lunar calendar, it is the solar calendar 6. 12, and it is Gemini (5.22 ~ 6.2 1).
There is also the calculation of the rising constellation, which needs to know the exact birth time. Generally, it is different from our own sun constellation (that is, the constellation we usually say). Even if you were born on the same day in the same year, if you check the date of birth for a few minutes, the rising constellation may be different.
