Some of these may have been corrected with a very recent commit - let me convert this to a python unit test format and give it a run against the dev version.
Thanks bear for your timely response. I'll await what you discover. In meantime, I made a minor (1-line) update to the above code gist, for more-readable output format, example below.
Also: I really appreciate the dateparsetime library. Saves me a lot of work.

All of these should be working now except for those that are +/- # format, like
-1 sunday
The reason for that is that the -1 is a modifier for a default unit of the phrase that follows but not a next/last modifier - so it will determine the date for "sunday" and then adjust it by a single day.
marking this as closed
and... that should have been on the issue and not on your code - sorry!

The following shows command-line session + output executing the above script on a test machine. Notice the inconsistencies/inaccuracies on some of the conversions.
