Bill,
Good news: the option is in OWL-Time for any length week that you like (though for compatibility with XSD there is probably a limit of 99 days)
Bad News: you have to write the ontology extension.
I did have a use case of 8 day weeks, as used in Cameroun SW Province grasslands for market days. Probably related to the Yoruba 4 day week, so really they are fortnights. The days of the week are: Zingana, Nkwafurh, Zinkab, Mbigndum, Zinkun, Nkwanying, Mbi'neh, Zisana.
It is quite a nice pattern: work three days, rest, work three days, go to market.
HTH, Chris ;-)

Subject: QB4ST example
Hi Rob
Unsurprisingly, I have run out of time to work on a good example for the QB4ST document. So instead I'll insert a note to mention that future work will involve preparation of further examples of how the ontology would be applied in practice.
Sorry - hoped to have done more but time moves too quickly these days. Should have asked Simon to add the option to OWL TIme for 8 or 9 day weeks.
Cheers
Bill
