# reason: can we ever make better guesses (in general) than just providing iso formats?
# I'm thinking: no
# also: space-wise, there's always a window where you want all info (perhaps maybe the year). Namely: a couple of days
# ago,
#
# Further thoughts:
# you can also _decrease_ specificity when going back in time, e.g. "november 2022" or "Tuesday"

    [ ] format dates as ISO-like (or with short month notation),
        never showing more than necessary.

        chunks for consideration will be:
            time-only: when it's on the current day.
                or even: when it's on the current day or no more than a couple of hours ago.

            day and month: not on current day, but no more than (365 minus small number) ago ... or the same: boundary or a few months
                idea: if it's almost a full year ago the disambiguation will be helpful, and this also helps against confusion

    # take a look at how the standard Django filters deal with local time.
