Is it a lunar birthday or a solar birthday?

Divination is based on the lunar calendar, that is, it is neither a lunar calendar nor a solar calendar. It is based on 24 solar terms. One month before the festival is the last month, and one month after the festival is the next. If someone was born on the tenth day of the first month of this year, if beginning of spring is in 1 1 month, the lunar calendar is still the ugly month of last year. If he was born in 65438+ February 25th this year, and beginning of spring was born in 65438+February.
