62 1 constellation _ What is 62 1 constellation?

Why are some Geminis 522-62 1 and others 52 1-62 1? Which one is it?

Gemini Date of Birth: May 22nd-June 2nd1

Because I was born at the junction of two constellations, it depends on the year of my birth and the corresponding time, such as:

Before1950 May 2 1 23:27, Taurus followed Gemini.

1951May 22nd, before 5: 15 was Taurus, then Gemini.

This is because there is a leap year.
