OK, first one I am stuck on.
"People staying overnight on 27th March 2011"
Well, which night is that. There are 5 hours and 50 minutes of night at the start of the 27th and 5 hours and 55 minutes of night at the end of the 27th.
Do they mean both ends of the 27th or just one?
I am sure loads of people will have opinion on this, but what is the legally correct definition and how do I find out?
