KDP Publishing Calendar 2026-2027: Publish-By Dates for Every Holiday

How the dates are worked out

Each date is a count back from the holiday, one delay at a time, with KDP's figures and our estimates marked.

1. The buying window: when people start looking

Nobody buys a Christmas book on Christmas Day. Gift and seasonal buyers shop from roughly two to six weeks before the date, and a book has to be in search results before they start. This is our estimate, not a KDP figure: six weeks for Christmas (from 13 Nov), five for Halloween, four for Easter and back to school, three for the rest. Earlier does no harm: a book live in September has longer to collect reviews before December.

2. Search visibility: up to 72 hours

A live book is not yet a findable book. KDP's timelines page says a book can take "Up to 72 hours after your book is live" to appear in search results. So the planner wants the book live three days before the window opens.

3. KDP review: 72 hours, 6 days, or 3 to 4 weeks

When you press publish, the book goes to In Review, then Publishing, then Live. KDP's figures:

• Most books: "it takes 3 business days for your book (or update) to be live on Amazon", and for print, "Up to 72 hours for Amazon.com; up to 5 days for other marketplaces". The planner counts three business days back from the live date, so a weekend adds two days.
• A first print book: "for accounts without a previously published book, publishing may take up to 6 days." That moves a Christmas paperback from 5 Nov to 4 Nov.
• Low-content books: "low-content book reviews are taking longer than usual right now and may take 3-4 weeks to complete." The planner uses four weeks. This is the delay that catches most journal and planner sellers out.
• Nothing speeds it up: "reaching out to Customer Support will not expedite the review process".

Coloring books are not low-content. KDP lists coloring books and puzzle books as "Not Generally Low-Content" and says the category "does not typically include activity books", so they get the ordinary review time. Notebooks, planners, journals, log books and prompt journals are low-content. The full rules are in our guide to low-content books on KDP. If a book bounces back to Draft, the clock restarts; the usual reasons are in why KDP rejects books.

4. The weekly limit: two new titles per format

Since 21 September 2026, KDP accepts "Up to 2 new titles per book format each week", counted the first time you submit, and separately lets you create up to two titles per format a week, drafts included. The limits "reset every Sunday at 12:00 AM Coordinated Universal Time (UTC)". It was ten a week before. One book is not affected; a seasonal range is. The planner gives the last pair of books the submit-by week, and every earlier pair the week before that.

5. A printed proof: our allowance of two weeks

For a paperback, order a proof copy before you submit: margins, spine text and cover colour are easier to judge in your hands. KDP does not publish a print time for proofs. It says you will get an order link "Within 4 hours of submitting your proof request", that proofs "don't qualify for free or Prime shipping", that "we're not able to expedite the process to manufacture your order", and that you can order "up to 5 proof copies at a time". We allow about one to two weeks and the planner uses 14 days; the real estimate is shown at checkout. Untick the proof box and a Christmas paperback can start on 1 Nov instead of 18 Oct, at the risk of a printing problem going live.

6. Making and editing: a few days

With Inkfluence AI the draft is the quick part: a book, coloring book or picture book in minutes. The time goes on reading it through, the cover and the files. The planner allows four days for an ebook or paperback, three for a coloring book and two for a journal or printable.

When people actually start: seasonal books made on Inkfluence AI

We counted the Halloween and Christmas books people made on Inkfluence AI this year, as a share of all books made each month. The pattern is the same for both: most seasonal books are started inside the buying window, which for print is late.

• Halloween books tripled from August to October: 23 per 10,000 books made in August, 36 in September and 76 in the first 18 days of October. Weekly, 35 Halloween books were started in the week beginning 14 September and 42 in the week beginning 12 October. At least 121 of the year's 279 Halloween books (43%) were started from the week of 21 September onwards, after our submit-by date for a Halloween paperback (18 Sep). Not every one was meant for print, but every printed one among them missed the start of the window.
• Christmas books run all year and then jump: between 32 and 53 per 10,000 every month from March to September, then 90 in the first 18 days of October. The busiest week so far was the week beginning 12 October, with 60 Christmas books started. The Christmas paperback start-by date in the planner is 18 Oct, so the peak lands right on the deadline.
• Christmas means fiction: 62% of the 608 Christmas books (by 494 authors) were novels or stories. Halloween is closer to even: 54% fiction among 279 books by 211 authors, with picture books, guides, cookbooks and journals making up the rest.

Late books do not fail by default, but the start date is earlier than it feels: a Christmas paperback started in the third week of October has no slack for a proof, a rejection or a second book.

Method. Counted on 19 October 2026 from books made on Inkfluence AI, our three test accounts excluded; aggregates only, no individual books or authors. A book counts as Halloween if its title or brief contains "Halloween" or "trick or treat", and as Christmas if it contains "Christmas", "Xmas", "Santa" or "nativity"; a few unrelated titles (a character called Santa, say) will be in the Christmas count. Monthly figures are per 10,000 books made in the same month; October covers 1 to 18 October. Weeks start on Monday. Fiction share is from the book's type. Free to cite with a link to this page.

Missed the print deadline? The two late options

A missed paperback date does not have to mean a missed season. Two formats have no proof copy and no printing, and one has no review at all.

A Kindle ebook

An ebook skips the proof and the print queue and reaches the reader seconds after purchase. Review is the same 72 hours, then up to 72 hours for search, so the latest useful Christmas submission is about Wed 16 Dec 2026. It suits novels, stories and non-fiction. It does not suit coloring books or fill-in journals, which need paper. Our guide to publishing AI-assisted books on KDP covers the upload, and KDP's AI questions are explained in the KDP AI disclosure policy.

An Etsy or Gumroad PDF

A printable has no KDP review, no slot limit and no shipping. Once the listing is active, buyers download it the moment they pay and print it at home, which is why printables sell right up to the day: a Christmas activity pack can be listed until Thu 24 Dec 2026. Coloring pages, activity packs, planners and journals all work as PDFs. Inkfluence AI exports a PDF on every plan, and on paid plans sends the book to Etsy or Gumroad for you; check the listing and switch it on. If you are not sure which digital format to sell, our list of digital product ideas compares them.

Often the answer is both: the paperback for buyers who plan ahead, the ebook or printable for everyone else.

Seven seasonal KDP timing mistakes

1. Counting back from the holiday, not the buying window. A book that goes live on 20 December is live for the last few days of a six-week season.
2. Treating a journal like a novel. Low-content review may take 3 to 4 weeks. A Christmas planner submitted on the paperback date (5 Nov) could still be in review in December.
3. Saving the whole range for the last week. Two new titles per format a week since 21 September 2026. Ten books need five weeks.
4. Forgetting your first book takes longer. Up to 6 days for print on a new account.
5. Skipping the proof to save time, then fixing a cover after launch. An update goes back through review: that is another three days off the window.
6. Planning a print pre-order. KDP has none for paperbacks; use a scheduled release, which low-content books cannot have.
7. Giving up when print has passed. The ebook and the printable sell almost to the day. Publish them and plan the paperback for next year.
