Can a person have two constellations?

Maybe, because some people have two birthdays, and the dates of the two birthdays are different and not in the same month, so there are two corresponding constellations.

Because we record our birthdays, some people use the lunar calendar, that is, the first few days of each month, some people use the solar calendar, that is, we now record the date of each day, and some people use both the lunar calendar and the solar calendar when recording their birth dates. Because the lunar calendar has 30 days each month, and the solar calendar has a big moon and a small moon, the dates of the lunar calendar are different. In addition, the lunar calendar has a full moon and a leap year, and there are some differences between the two birthdays.
