RE page: http://www.us.debian.org/doc/manuals/project-history/ch-detailed.en.html "The sixtth Debconf was held in Espoo, Finland, between July 10th to July 17th, 2005 with over three hundred participants. Videos from this conference are available online." "sixth" I'd also suggest a wording change: "FROM July 10th to July 17th, 2005" (or) "between July 10th AND July 17th, 2005" - T. P.S.
