Why do people in China celebrate their birthdays in the lunar calendar?

Because traditional China people calculate birthdays according to the lunar calendar, the first birthday of a child is called "one year old".

China people's new year begins on the first day of the Lunar New Year, which means that after New Year's Eve, everyone grows up by one year. Therefore, saying goodbye to the old and welcoming the new also means that it contains certain age significance.

However, the general birthday is still used to the lunar calendar. So everyone can have two birthdays, one in the lunar calendar and the other in the solar 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.

Birthday celebration method

Birthdays for the elderly are usually birthday noodles and birthday bags made by children themselves; On children's birthdays, parents will give them red envelopes as keepsakes.

No matter when the old people and children celebrate their birthdays, they should boil eggs to eat. The first birthday is one year old, which is almost the most important birthday. In the past, old people divided their birthdays more carefully. If it is the birthday of respected parents in a big family, there will be corresponding celebrations. Traditional birthdays are generally calculated in nominal years.
