Spring or Summer 2011

We are informed that Prince William and Catherine (Katie) Middleton will get married in the Spring or Summer next year. When could this be?

Assuming they want to try and have a sunny day it will have to be no earlier than late May, no later than early September and preferably not in August when most of the wealthy decamp to their holiday homes in the Dordogne or Tuscany

So let's look at the social and sporting calendar for next summer: the Season and others, in London and Cardiff (bearing in mind the Welsh connection):
Chelsea Flower Show - 24 May 2011 to 28 May 2011 - Royal Hospital, Chelsea
England v Sri Lanka Test Match - 26 to 30 May 2011 - Cardiff
Epsom Derby 2011 - 3 June 2011 to 4 June 2011 - Epsom Downs Racecourse
England v Sri Lanka Test Match - 3 June 2011 to 7 June 2011 - Lord's
Queen's - 6 June 2011 to 12 June 2011 - Queen's Club
Royal Ascot -14 June 2011 to 18 June 2011 - Ascot Racecourse
Wimbledon  - 20 June 2011 to 3 July 2011 - All England Lawn Tennis Club
England v Sri Lanka ODI - 28 June - The Oval
Henley Regatta - 29 June 2011 to 2 July 2011 - Henley
England v Sri Lanka ODI - 3 July - Lords

British Grand Prix - 08 July 2011 to 10 July 2011 - Silverstone
Wedding of Prince Albert of Monaco -  9 July - Monaco
The Open Golf Championships - 14 July 2011 to 17 July 2011 - Royal St George's Golf Club
England v India Test Match - 21 July to 25 July - Lords 
England v India Test Match - 18 to 22 August - The Oval
England v India ODI - 9 September - The Oval 
England v India ODI - 11 September - Lords 
England v India ODI - 16 September - Cardiff


So it looks like 31 May to 2 June, 19 June, 4 July to 7 July, 11 July to 13 July, 18 July to 20 July, 26 July to 17 August, 23 August to 8 September, 10 September or 12 September to 15 September.
