Hello ~! The correct calculation basis of the twelve constellations is the Gregorian calendar, which is what we call the solar calendar.

If you were born in February 9 1 and 14, then your date of birth in the solar calendar is March 29th +099 1.

Because the twelve constellations must be calculated according to the solar calendar, so you were born on March 29th, 199 1, then you belong to Aries.
