zgirnius:
There is a typo of some sort here, Dana. 3.31 minutes? Do you mean 
about 30? The why do you later suggest full dark is at 10:50 in 
Edinburgh? I will assume this is what you meant, as you go with it 
for the rest of the post.

zgirnius:
If 10:50 is your proposed arrival time AND the moment of full dark, 
then you looked up the wrong places for end of twilight. You say this 
is end of twilight, AND when Harry arrives. Hence, you should be 
looking when the end of twilight happens in London, England. As it is 
some 300 miles south of Edinburgh, I suspect it happens earlier in 
London than in any of the three cities of Scotland you mention. 

In fact, a check of the source you cited shows a time between 9:10 pm 
and 9:25 pm for sunset in London, depending on whether we look at 
early or late June. Which gives 10:10-10:25 for full dark assuming 1 
hour. (As you seem to in Edinburgh). Harry leaves school at 9:50 and 
arrives in London about thirty minutes later, doing considerably 
better than the plane service connecting those two cities for 
Muggles. I find it hard to believe this is the time lapse Rowling 
intended, and conclude this exercise is probably doomed because she 
simply did not look this stuff up. Certainly, my subjective 
impression of the length of the trip was not 30 minutes, and that is 
what I trust more, as describing people's feelings seems more her 
forte than astronomy/timelines/maths. Harry loses all track of how 
long and how far they travel in that time.
