Date of birth of the type "YYYY-00-00" / "00/00 / YYYY"

Question

In my country (France), some people have a date of birth, for example YYYY-00-00( 00/00/YYYY). This legal agreement (and is used on identity cards) is usually for immigrants who do not know the exact date of their birth.

Of course, the problem is with databases and algorithms.

Have you ever faced such a situation? How do you deal with this? What will be your choice?
