EDIT:
I realized that the solution (below) was nonsensical for what I wanted as I was working with relative dates…while I need specific year that doesn’t change if the query is run next year :roll_eyes…so how can I get something like:
WHEN finished (YAML date field like "2022-03-10") contains year "2022"
EDIT: That’s the solution for relative dates in case could help someone…
I could get it, thanks to a post from @Moonbase59

WHERE finished.year = (date(now) - dur(1 year)).year
