Hi ԱշոտՏՆՂ,
It seems that this edit may have added all people with date of birth (P569) to the category for deaths of that year. The result is that, e.g., Wikidata:Database reports/Deaths at Wikipedia/1988 includes lots of incorrect entries from hywiki (this category). As I don't edit hywiki, I don't want to try to fix it. Would you help me?
