Inspired by a link Ben sent me earlier, I got a bug report from QA today that stated "events added in the admin only show in the client on their start and end date." This is not terribly uninformative, but of note is the fact that this code was originally written by someone considered to be one of the "best" coders at a former employer of both Ben and myself. I found and fixed the issue and put in this as the resolution: "Actually it appears that some very smart person wrote Access date checking code that was quite simply... stupid. I have unstupided it." I don't know why I felt like sharing that, but I did.
