Just started listening to the GoT audio books at work, and something has annoyed me about 5 lines into the 1st chapter. 'It was the 9th year of summer'. How does that work?
But that defeats all rules of Astronomy surely? If a planet revolves a start it has seasons, and he says in the same sentence that Bran is in his 7th year and we know the Bran is a young child, so he is suggseting that Years in the universe are the same as we know on Earth, but the season has lasted 9 years. IT DOESNT MAKE ANY SENSE.
Years are years(365 days and whatnot), season are many years. Astronomy and earth vs sun rotations aren't the same(or really relevanat) in a world of magical spirit pooping vaginas, undead frostybeards and dragons

George RR Martin has basically said there's no science behind the SOIAF universe; he wanted the seasons that way so he wrote it that way. However, if you did want to get scientific about it, you could have variable seasons with fixed years. If the planet had no axial tilt, the solar orbit was almost perfectly circular and the star was a bit more variable than ours, the seasons could vary in the way described in the book, e.g. no-one knows how long a season will last because its not directly related to the planet's orbit but rather almost entirely on the behaviour of the star.
Informative, BUT! If the planet had no axial tilt and the orbit was perfectly circular surely there would be no seasons at all, and it would always remain sunny or dark in the different hemispheres. How does solar activity effect it? (Moving on from the GoT bit, just general interest now if you know a bit about these things)
Tilt doesn't cause day/night, that's rotation. It causes seasons though because as a particular point on the earth tilts away from the sun it is colder. If there was no tilt then you would have the same temperature all year round, ie the equator where there isn't a lot of difference in the seasons.

I suppose in the GOT universe you could have extreme but slow tilt which could also cause long periods of hot and cold.
It's in the fantasy genre. If you find THIS fucked up, you're in for a rough ride.

The best science fiction writers are clueless to how science actually works and thats why they are so creative
