So this is specifically for sorting movies by period pieces, using that as a broad term just for any film not set in the modern day. This won't apply to movies that came out in the year it was set in, for instance don't put a movie that came out in the 90s that was set in the 90s. If a movie is set across multiple decades, you can just put them in each or whichever is prominent, that’s what voting is for it’s a matter of opinion.
