If memory serves, Mr Allan holds the calendar as sacred, inviolable space – not dates in general.

My company uses timesheets, for instance, that are required to be filled out by 10:00 every morning. I don't want to clutter my calendar with an appointment, but this still needs to be done -- and OmniFocus is the perfect tool to gently remind me at 9:50 (via Growl) that my timesheet is due. I find it useful to just skip the weekend (defer 2 days).
