Very close - as expected - the only difference is my calculations 
yield Civil Twilight as starting three minutes earlier in the 
morning and ending three minutes later at night (I suspect the US 
Navy uses a slightly different definition of Civil Twilight than is 
standard). Not that relevant. And the Summer Time issue I mentioned 
earlier also needs to be considered - you've used Universal Time, 
which I think is probably correct for the Wizarding World, but I 
don't think the possibility of daylight savings can be eliminated.

Not a problem - if you can get the data, great. It's just I can get 
a lot more data on occasions when that's relevant - for example, 
the magnitude of Mars on a particular date - quite easily.

There's also issues, just for the record - that there are two forms 
of twilight - civil and nautical. Civil is what normal people (ie 
non-astronomers) normally refer to as twilight and it's what I 
would normally expect JKR to be using - however, one of her 
references - I haven't time to check it right now, IIRC, really 
seems to indicate Nautical Twilight may have been involved on this 
occasion - and that is slightly problematic astronomically as as 
far north as Hogwarts is, you don't really *get* out of Nautical 
twilight in mid-June!
