I have found that even UK dates for stuff happening aren't normally confirmed until late december. Unless it's a huge, huge event. You maybe advised to just keep surfing the sites where these dates would be most likely found. eg for places like Spa go on their own web pages and the like.
I have to agree it's really awkward if you have to book leave a long time in advance.
Good luck sorry I can't help.
