A little more context for anyone not aware. Epistolary just means it's like the book equivalent of the Blair Witch Project. It claims to be written not by some outside author like most books, but to be the literal transcriptions of the characters' diary entries, letters, news articles, and phonograph recordings. All of these are of course dated in-universe, with the first of Jonathan Harker's diary entries taking place on 3rd May. So we're reading through it as it happens.

Days 1 and 2 are very short, and there isn't any entry on 6 May, so you've got plenty of time to catch up if you want to join in on 7th May.

Minor correction: the days don't actually match up to "chapters" of the book. Chapter 1 is made up of 3, 4, and half of 5 May. Chapter 2 is the 2nd half of 5 May, 7 May, and the 1st half of 8 May. I'm not 100% sure as I've never read the book this way before, but I believe later on, doing it this way will actually mean we read it slightly out of the normal reading order, too, especially as relates to the news articles and shifting POVs.
