Alot of people ask us, where is Hogwarts located, well, here is a well thought out and written answer.A number of facts from the books point to Scotland, a bit north of Edinburgh, and possibly closer to Aberdeen. The primary routes to Scotland from London depart from King’s Cross. You cannot go more than five hours from London on a steam train in a consistent direction, and stay on dry land, without going into Scotland. At Nearly Headless Nick's Deathday Party, JKR described some of the rotten food as haggis, which is a traditional Scottish dish. A member looked up latitude, longitude and sunset times on Sept 1st and on June 6th, 1993, the days of major events in PoA, and this information suggests Scotland for the likely locale as well.
Another question asked, is where is the whole setting taking place.Atlas of Wizarding BritainMap of Central LondonAlast, another question used, when, does the whole story take place.There is few rules here and you must be up with the time line.
Voldemort is still alive, so Harry has not found all the Horcruxes, meaning it may be in the mid-begining of the 6th book. Dumbledore, Snape, Sirius, and Cedric are still alive, thus leaving out a death line, any other non important character's may live as well. With an exception.
People are probably wondering, why bring these characters back to life, well, why not, they deserve to be alive and important just like any other character.
Please follow the timeline, or I will be very upset.
