I spend an awful lot of time thinking about Dates, not the going to a restaurant and the cinema type, but the period of time.
I guess that to an extent we in the UK are in a similar situation to the rest of the world when it comes to English as most web-based technologies use American date format, which is a pain!
The American's use Month, Day and then Year when they write down their dates... that's just silly! We use Day, Month and then Year... which is cool and goes from smallest to largest whereas the American version goes from the middle to the smallest to the largest - where's the sense in that? I guess that to some extent it might be because they're used to measuring dates in terms of Months - perhaps because it used to take weeks or months to get from one end of their country to the other...?
Whatever the reason though, it's just silly! Ohh, and a pain!
