A thread for anyone else like me who wants to stay free from spoilers in the HBO show starting with this new season, but still be able to discuss the phenomenon that is A Song of Ice and Fire. I'm somewhat OCD about staying spoiler-free on things I care about, and also something of a purist on storylines (e.g., no Special Edition for my wife and kids, thank you very much George Lucas!), but I still want to be able to talk about the books and speculate about the world G.R.R.M. has created and speculate about what may happen in his work, as distinct from the show.
That being said, if anyone wants 0 spoilers from the books, say so and we can use spoiler tags in here.
My first question, if anyone wants to discuss (this came to me yesterday when I was listening to Game of Thrones on audiobook): does Westeros have months? Can Westeros have months, since seasons are of irregular length (i.e., something's "wrong" with their orbit such that they don't have a standard revolutionary pattern)? How do they divide their time periods and know when to celebrate name-days? Is it just that they have years of standardised length, and then winter comes and happens to last for multiple years? What's the standard for dividing time?
