This doesn't follow the syntax of the (:if:) markup -- the
thing immediately following the "(:if " has to be the name of
the condition.  Of course, one could do

    (:if date <20051020 :)    strictly before Oct 20
    (:if date >20051015 :)    strictly after Oct 15
    (:if date <=20051020 :)   on or before Oct 20
    (:if date >=20051015 :)   on or after Oct 15
    (:if date >=20051015 <=20051020:)  Oct 15 through Oct 20
    (:if date >=20051015 <20051020:)   Oct 15 through Oct 19

but I think non-math-oriented folks may frequently forget
about the ">=" and "<=" forms when writing dates and thus end up
with things starting a day later or ending a day earlier than intended.
