Excuse me, is the person whose birthday is in the twelfth lunar month one or two years old?

For example, someone was born on the 29th of the twelfth lunar month in 2006, and we know that the solar calendar is already February 15, 2007.

In some places, the age is recorded by the lunar calendar, so when the solar calendar is in April 2008 and the lunar calendar is around February 2008, this person's lunar calendar age is three years (2006, 2007 and 2008 account for three years), while his solar calendar age is less than two years (2007 and 2008 account for two years), so he is only two years old. In fact, his life span is only 18.

In comparison, there is a saying that you are two years older.

In some places, the age is recorded by the Gregorian calendar, so the nominal age can only be one year.

Moreover, the method for calculating the age in the China census is as follows:

Those born in the first half of the year are one year old, and those born in the second half are one year old. For example, if you were born in March 1980 and went to the census in 2008 (whether in March or June, 10), you will be 29 years old (808 1, ... 07, 08, a total of 29 years). If you are 1980, 10.
