Is the birthday a lunar calendar or a solar calendar?

According to the tradition in China, you should choose the lunar calendar. But now the date of birth of the child is determined according to the Gregorian calendar, so it is ok to celebrate the Gregorian birthday, but it should be noted that only one can be chosen, not both.

However, it is customary to use the lunar calendar for birthdays. So everyone can have two birthdays, one in the lunar calendar and the other in the Gregorian calendar. Because the China Lunar Chronology Law is a revised monthly calendar, which is related to the moon period of revolution, the corresponding Gregorian calendar date is different every year.

The reason why we celebrate our birthday according to the lunar calendar.

Lunar calendar is a traditional calendar in China, which has been handed down from generation to generation in China, so people in China are used to celebrating their birthdays. The lunar calendar is a traditional calendar in China, and it has other names, such as the lunar calendar, China calendar, Xia calendar, Han calendar and China calendar. The lunar calendar takes the change cycle of the moon phase, that is, the length of the moon as the month, plus the "24 solar terms" component of the dry calendar, and takes the length of the tropical year of the sun as the year. By setting leap months, the average calendar year will adapt to the tropic year.

Gregorian calendar is a calendar in which the earth revolves around the sun for one year, which is different from the lunar calendar. The lunar calendar is a calendar based on the lunar calendar (summer calendar) and combined with the solar calendar. Therefore, the lunar calendar in China should not be called strictly lunar calendar, but a combination of yin and yang.
