I make a lot of my own books for tl;dr reasons (not available in my language, so I buy them in the original and download translations.)
I can't seem to figure out what metadata to put in the html header so Calibre can pick up the publication date!
Nothing I've tried works.
I use Amazon Kindle and Mobi, not epub.
My current header is:
Code:
<html><head><title>Usemono Yado ENG 01 うせもの宿(1) (フラワーコミックスα)</title><meta name="author" content="穂積 Hozumi" /><meta name="tags" content="Decrypted Ebooks, Drama, Josei, Manga, Mystery, Romance, Slice of Life, Supernatural" /><meta name="series" content="Usemono Yado ENG" /> <meta name="isbn" content="9784091364166" /><meta name="publisher" content="株式会社小学館" /><meta content="2014-10-10" name="dcterms.date of publication" /><meta name="primary-writing-mode" content="horizontal-lr"/></head>
