I just renewed my Prime membership today and it use to say expires 6 Oct 2019 now it says expires 5 Oct 2020. Since I was under the impression renewal should be added on the end of my current membership shouldn't it expire on the 6 Oct 2020? It seems I am missing a day. Not a super big deal, however if I renewed a month ago would I then be missing the month?
