Summer solstice stats

Happy solstice!

I don't really know the distinctions between night, astronomical twilight, nautical twilight, civil twilight, and daylight -- except that the first one is dark and the last one is light -- but the Internet says that today we had 16 hours 7 minutes of daylight, 1 hour 24 minutes of civil twilight, 1 hour 58 minutes of nautical twilight, 3 hours 51 minutes of astronomical twilight, and only 40 minutes of actual night.

This is thoroughly unimpressive compared to most of Canada, and even Vancouver, because Victoria dips down below the 49th parallel. Still, it seems kind of cool.

The city where I was born had no minutes of true night at all, and 17 hours 8 minutes of daylight. My friend F. lives on the Isle of Iona; they had no night or astronomical twilight, and 17 hours 42 minutes of daylight. In Reykjavik, they had 21 hours and 8 minutes of daylight, and the remainder was civil twilight.

You?
