Is the birthday a lunar calendar or a solar calendar?

In fact, for China people, birthdays have always been based on the lunar calendar. However, due to the addition of the solar calendar, in order to facilitate calculation and statistics, the birthdays displayed on our ID cards are now based on the solar calendar. For China people, everyone has two birthdays, one in the solar calendar and the other in the lunar calendar, but traditionally the lunar calendar is the main date.

Because the solar calendar is calculated according to the revolution of the earth, there is a difference between a flat year and a leap year. Although there is a clear stipulation in the solar calendar, if a person born on February 29th of a leap year celebrates his birthday according to the solar calendar, then this person can only celebrate his birthday once every four years, so it is better to celebrate his birthday according to the lunar calendar.

In addition, many Chinese zodiac signs and zodiac signs in China are mainly based on the lunar calendar. If one year happens to be the year when the lunar calendar meets the solar calendar, then people born here will have two completely different zodiac signs. So in order to avoid this situation, it is best to use the lunar calendar algorithm for birthdays.

You can check your birthday by birth certificate, household registration book, ID card and other documents that can prove your identity. The birthday on the ID card is in the solar calendar.

Lunar birthday is the lunar date on the day of birth. If the birthday falls on the lunar calendar, the birthday of the second year will not be the same as that of the first year, because the number of days in the lunar calendar is different every year. The calculation method is: this year's lunar birthday = last year's lunar birthday+this year's lunar days. The number of days in the lunar calendar is as follows:

12 months has an average of three days in a year:

1, five big months, seven small months, 353 days (e.g.1965b).

2. Six big months and six small months, totaling 354 days (for example, in 2005).

3. Seven big months and five small months. She leaned over and lied and stabbed Hanla for 55 days (the same as in 2003).

There are three days in thirteen months of a leap year (a leap month means an extra month).

1, six big months, seven small months, 383 days (e.g. 1993 Gui You year).

2. Seven big months, six small months and 384 days (such as Shen Jianian in 2004).

4. Eight big months and five small months, totaling 385 days (for example, the year of Xu Bing in 2006).

The average year of the lunar calendar is 10 to 13 days less than the Gregorian calendar, and the leap year is 17 to 20 days more than the Gregorian calendar.
