That's highly subjective...

What about DateTime::Format::Human ?

edit

or DateTime::Format::Human::Duration ?

update

using https://grep.metacpan.org/ with dists starting with ^DateTime.* ending on *.pm and matching permutations of yesterday last week ago produced

• DateTime::Duration::Fuzzy
• DateTime::Format::Natural
• and more.

unfortunately grep-metacpan was often not reliable in listing the matches, so I gave up searching for more.
