Cannot use year (ie, 2008) in page slug

[chrismou]

WordPress doesn't seem to like the idea of me using "2008" or "2007" as a page slug.

The situation is that I'm writing a page a year dedicated to a festival I go to. The front page is located at mou.me.uk/glastonbury, and sections for each year would be located at mou.me.uk/glastonbury/2007/ and mou.me.uk/glastonbury/2008/ respectively.

BUT, when I try and view either of these pages, it shows me the page located at mou.me.uk/glastonbury - ie, the parent page.

Bizarrely, when I entered mou.me.uk/glastonbury/2007/a/ (just to test), it redirected me to a post I wrote in 2007.

I assume that this is not intended behaviour? I can see the logic in trying to extract a date from the URL and find the closest matching post, but surely this should be overridden if Ive created a page where the slug matches exactly whats in the address bar?
