It varies by use case. I can think about e.g. an SRS flash card where you next review is in 2 years. I honestly don‘t care if 2 years here means 21 months or 28 months, and I especially don‘t care if the next review is on 21st of February 2028 at 13:52. All I want to know is that the next review is so far in the future it may not actually happen.
That's a fair point. I'm thinking of the use case of formatting a past date on something like a social media post/comment. (For example, a comment on HN - which uses a rather long cutoff for relative dates.)
