The point is, the Recurrence class in the recur module seems to have some hooks builtin for this sort of stuff, but it's not been fleshed out very well. A PEP with some sample implementations might go a long way to making a more complete implementation available. The documentation seems to be missing that would help me add it. I think there is technology there which doesn't exist in dateutil. Correct me if I'm wrong.

Perhaps recur.Recurrence just needs a little more work so it can handle some common timekeeping phraseology: * every Tuesday * every hour on the half hour * once an hour on the quarter hour * every 4 days * the first Monday of each month * every four years starting in 2000 I'll restate my suggestion that maybe a PEP for this stuff would be a good idea. I think it would be a reasonable idea to check both recur and dateutil into the nondist/sandbox so other people can take a whack at them.

Fine with me. I agree with your assessment that, although flexible, it's not fleshed out. I only built in the specific use cases I needed at the time. More would be nice regardless of how it interfaces with DateUtil. As far as a lack of documentation, I'd be happy to answer questions and then turn around and use those to write some more docs.

For a start, it probably needs a better "little language" lexer/parser than just regexes if you're going to fold in the examples above.
