If you are writing a book that covers a period of time, for example 14 days, would you
* put the date as the chapter title if multiple events happen on that day
* pick a prominent event in that chapter and use that as the chapter title
* Just call it Chapter 1, 2, 3, etc
* Not worry about Chapter titles?
Jimmy's got a good point there. Blurbs are written calculatedly to sell the book. Reviews are chosen on the basis of "most flattering, first served". How many times have you picked up a book with "HILARIOUS!" and/or "I literally couldn't stop laughing" slapped on the cover and found that it hardly raises a chuckle (on p. 56, 2nd paragraph)? And titles? We've all seen Q&As on this site asking for OTHER writers to "suggest a good title for my book". Agents and publishers also sometimes twist an author's arm to change the title. i.e. Titles are not always an indication of the writer's imagination.
So... you can go by the opinion of trusted friends (not ALWAYS trustworthy), you can read a few pages to decide if you like the style, or you can skim down the list of chapters to see if they "grab you".
p.s. Jimmy: could you lend me that "Bleeding Stiff" book once you've finished it?
I agree with Adrian on this. I find "Chapter 1", "Chapter 2", "Chapter 3", boring. I also sometimes put a book down for a few days (or months) without a bookmark. I like to be reminded just where I got to when I pick it up again. "Chapter 6" doesn't tell me anything.
"Tuesday, 8a.m." doesn't curl my toes either. "Tuesday, 8a.m., Another Bleeding Stiff On My Doormat." Now that's a different matter. For one thing, I want to know if the word "Bleeding" is being used literally or as an expletive. Almost better: "Tuesday, 8a.m., Another Bleeding Stiff On My Doormat. And I'm Out Of Coffee." This lets the reader know that the author has her priorities right.
We're past the days of Dickens and Jerome K. Jerome, when Chapter titles were often synopses of the chapter concerned. Now THAT's irritating, because they sometimes include spoilers. You DON'T want to know, before you start reader a chapter, that Little Peggy is going to peg it at the end of that chapter.
Composing good chapter titles is an art in itself. I often decide whether or not to read a book by reading the chapter titles.
I disagree with Adrian on this. For some reason chapter titles take me back to AA Milne and...'In which Christopher Robin...' etc, so I wouldn't use them in a novel. I can see how they might be more attractive than a list of chapter numbers as a Kindle content/search index, but time or place markers are subtly different in my view and I see no reason you can't use them at section breaks, chapter breaks or within chapters. Though the latter ought to be sparing and I wouldn't use a time-jump in this situation.
I think their main function is reader-help, when you're trying to move the story forward at a pace which may vary between sections. Or where actual time or place are critical to the reader's understanding.
But that's just me.
