1985 what is the constellation of Gregorian calendar 4,25?

5. 12 of the 85-year solar calendar corresponds to 3.23 of the lunar calendar.

Lunar calendar 3. 12 in 1985 corresponds to solar calendar 5. 1.

So one of the solar calendar and lunar calendar you provided must be wrong.

The constellation only looks at the date of the solar calendar on the day of birth, not the lunar calendar. Fortunately, whether it is 5. 12 or 5. 1, it is all Taurus.
