Okay! It’s done! It took me four days, but I’ve finished a complete update of the timeline. There have been a lot of corrections and additions (and I’m still working on adding some of the information about who won the House and Quidditch Cups for the last ten years). And hey, check this out:
Y-1 (1979) M=19 BW=8 CW=6 PW=3 FGW=1 LM=25
See those little notes in red after the date? That means that in that year (1979 in the example above) the marauders turned 19, Bill Weasley turned 8, Charlie Weasley turned 6, Percy turned 3, Fred and George turned 1, and Lucius Malfoy turned 25. I’ve added that to every year after 1971 (which is when Bill was born) and also to the years when McGonagall, Hagrid, and Tom Riddle were at Hogwarts. Is that cool or what?
Oh, and if you’re curious about the “Y-1″ thing, check out this page.
