For older actors sometimes exact date of birth or death may not be known but only a year. Without us being able to add the unknown date the person's age will be counted indefinitely.
For example, for Helene Santley here...

...only year and month of date are known (https://www.imdb.com/name/nm1897285/bio?ref_=nm_ov_bio_sm) but the engine doesn't support this.
Is there a work around this somehow to leave month or day in such cases? I tried adding just 1986-06 or just 1986 but the engine reported this as an invalid date. Do we just select first in the known month or year to force-enter it or just leave it unknown indefinitely?
