I'm trying to get a custom URL rewrite in place but having issues.
I have a page called 'Programme' which uses a custom query to list a post type called 'event'. I'd like to pass a month and day variable in the url, e.g.
I'll then use the month / day variables to update the custom query. (As the events span multiple days the built in archive for 'events' won't work).
Currently trying to add the rewrite results in a 404. Can I use the built in 'm' and 'd' variables, or do I need to register new URL variables?
