Is the date of birth on the spirit tablet nominal or real?

Generally speaking, the date of birth on the spirit tablet should be the real age, not the imagined age. The real age is calculated according to the birth age of the lunar calendar, while the imaginary age is calculated according to the difference between the lunar calendar and the solar calendar, usually one year or more older than the actual age. The actual age on the spirit tablet is more accurate and standardized than the imaginary age. Because there is usually no clear standard for the calculation of nominal age, the real age is calculated according to the Gregorian calendar date of the solar calendar or the lunar calendar, and there are relatively clear regulations. In addition, the actual age is easier for readers to understand, especially those who are unfamiliar with the concept of nominal age. In order to express more accurate information, it is suggested to use the actual age when writing the date of birth on the spirit tablet.
