It's at this point that the brainhammers move in, because if you're going to do a decent job of calculating DST, you need to know where you are, and I mean really know where you are. While all of Europe starts and ends DST at the same time, other countries vary wildly from each other, and some aren't even able to keep it consistent internally. Australia is a prime example: each state sets its own DST dates. Israel decides its DST start and end dates every year to ensure they don't clash with the High Holy Days. However, that doesn't include the Occupied Territories because the Palestinian Authority, clearly sick of all the mucking about, moved to solid dates at the first chance it had.Link Discuss
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
