Is the constellation calculated by solar calendar or lunar calendar?

You were born on August 28th of the lunar calendar.

You are Libra.

If you come from the countryside, your parents usually celebrate your lunar birthday. If you come from a city, you usually celebrate the Gregorian calendar. But this still depends on you, but few young people will care about what the lunar calendar is today, so I suggest you celebrate the solar calendar, at least you won't forget it, unless there are some special days in the lunar calendar, such as those days near festivals, so it will be better to celebrate the lunar calendar. For example, I was born in July of the lunar calendar 15, which is easy for my family and friends to remember, so I don't follow the Gregorian calendar.
