1991April 20th What is the constellation _1991April 20th?

1991what is the constellation on April 20th? Look at Aries and Taurus, which are at the junction, so how to define them? Not even sure!

Everyone belongs to only one sun sign, because the time when the sun enters the palace is different every year. If the birthday is at the junction of the constellations, it is necessary to check the astronomical calendar to determine the sun constellation to which they belong, and there will never be a situation that spans two sun constellations.

199 1 born before 22: 08 on April 20th is Aries, and 199 1 born after 22: 08 on April 20th is Taurus.
