1999.03.26 Who can tell me what constellation this is, solar calendar?

Hello, the constellation is a fortune-telling thing for westerners. Because westerners don't have a lunar calendar, we should first convert the birthday of the lunar calendar into the solar calendar, and then look up the constellation table.

If it is lunar calendar 1999.03.26, it is converted into solar calendar1999.05.11,which is Taurus;

? If it is Gregorian calendar 1999.03.26, it is Aries.
