How to reverse pages order on a EPUB

[FacetiousKnave]

Basically, I have a manga in EPUB format that has the page orientation set in a western order, this is LEFT to RIGHT.

Is there any way to reverse the order (RIGHT to LEFT) with Calibre?

How can you tell page order when only one page is shown at a time?
I know how to reorder a PDF, but it's only meaningful printed and bound, or two up side by side on a big screen.
AFAIK the epub L->R and L<-R only applies to paragraphs, headings etc, not pages as epubs, unlike PDFs and Word Docs, don't have left and right pages.

Perhaps you can explain in more detail the problem?

Are you making a manga to be read on your Kindle? If so then the Kindle Publishing Guidelines section on Creating Fixed-Layout Books with Image Pop-Ups or Virtual Panels lists the metadata that should be present in the OPF file. For page progression direction it states:

<meta name="primary-writing-mode" content="horizontal-rl"/>

Required for Virtual Panels in manga with right-to-left reading order; optional for other fixed-layout books. Defines page rendering order, reading mode, and reader navigation (including Kindle Text Pop-Up, Kindle Panel View, and Kindle Virtual Panels). Valid values are horizontal-lr, horizontal-rl, vertical-lr, and vertical-rl. The default value is horizontal-lr.

The default behavior is horizontal-lr when the page progression direction is left-to-right or not specified. Use the value horizontal-rl to set the page progression direction to right-to-left.

Use the value vertical-rl to set a page progression direction of right-to-left for Chinese, Japanese, and Korean books.
