Please tell me whether the month the child was born in the naming website refers to the lunar calendar or the solar calendar?

It is better to give the name to someone in your own family. If you don’t know it, you can search it online. The months mentioned on the naming website are based on the lunar calendar, and a person's birthday and birth date are calculated according to the lunar calendar, because the lunar calendar is based on the arrangement of the 24 solar terms, including leap months, etc. The lunar calendar (chronological calendar) stipulates that the winter solstice The lunar month in which it is located is November (Jianzi, called Tianzheng in some books). There are 12 lunar months if there are 12 intersections between two winter solstices (about one tropical year apart). There are 13 months with 13 new moons, and the month without solar energy is a leap month. This is the reason why there is a leap November in 2033 instead of a leap July. A person's birth date and horoscope are calculated according to solar terms, not natural months. For example, if a child is born before the 21st of the twelfth lunar month this year, he or she will be born in the zodiac of Ox, and any child after that will be born in the year of tiger. Yes, because this day is the beginning of spring, and the beginning of spring is the real new year, not the day of New Year's Eve
