It's rare I'm stumped finding a subject on a searchengine

I thought it would be straight forward
However 2 of us could not find a site with the answer
So can any Answerpooler help find a list for us?
Ok .the Task I set myself was to find a list of "early closing" days for shops in the UK
Normally they close Halfday on Wednesday Afternoons But there are variations within towns
Where I live the half day is taken on Mondays,Wednesdays and Thursdays (Different areas of town) Confusing for strangers(Local knowledge comes in handy on this)
The only list published was in the Automobile Association Handbook many years ago.
But as far as I can see there is no Official list published (Tried local government) unless I'm using the wrong key words
Additional question: Is "Half day closing" a British only tradition?
