Did you know?
- While 生年月日 is used for bureaucracy, Japanese culture has a traditional 'birthday' called 数え年 where a person is considered one year old from the moment of birth.
- In official records, a person's 生年月日 might be recorded using the Japanese era system, which resets the year count every time a new Emperor ascends the throne.
- The character 生 in 生年月日 is the same character used to describe 'raw' fish in 'sashimi' or 'raw' beer, as both refer to something in its natural, unprocessed state.
