Using `>` and `<` for dates is a bit confusing because it usually
requires mentally translating `<` into "before" and `>` into "after",
meaning it takes a few seconds to check which is the starting date and
which is the ending date. When using a range, it's easier to see which
is which.
Note that we were using `>` and `<`, but now we're using the equivalent
of `>=` and `<=`. This makes sense IMHO, since the beginning of the year
and the end of the year should also be included in this case.
