Doesn't the poles get normalish day/night cycles during autumn and spring? If so, it would be a bit more than just a few hours of sun light each year.

- LadyCailin 4y agoNo. That’s literally what the article is about.
- netsharc 4y agoYour question made me wonder why the cycle would be a year long. I realized that's because when standing at 90 degrees north or south you're just rotating on the spot. There's only the yearly day/night cycle because of the 23.5 degree tilt of the earth's axis, and this doesn't change relative to the plane of the orbit: https://www.youtube.com/watch?v=e9MU4TouzII&t=61 https://www.youtube.com/watch?v=e9MU4TouzII&t=61 This also explains why across 24 hours on the video in the blog the sun just "revolves" at the same height across the sky. In reality it's setting but it's imperceptible. At less than 90 degrees (anyone know the longitude?), the earth's rotation comes back into effect and the sun does go "behind the earth", i.e. it sets, daily, for a few months.

I was wondering too. It looks like it's at about 84 degrees that there is a normal day night cycle (for some definition of normal, there is only a few minutes of daylight at the winter solstice).
- aflag 4y agoYeah, that makes sense. It's actually not that surprising when you think about it. I'm not sure how vampires deal with Twilight. There's a long twilight in those regions.
