About the leap year constellation.

Constellations only look at the solar calendar, not the lunar calendar.

The leap solar calendar only falls on February 29, more than four years, and this day is definitely Pisces.

There is usually one more leap month in the leap lunar calendar, but the constellation is based on the birthday of the solar calendar, so it is not directly related whether to convert the lunar birthday into the birthday of the solar calendar and then check the constellation.
