[TwentyFifteen] Post date translation

My translated TwentyFifteen theme shows the following date format in the footer of a post:

Lipiec July 29th at 5:10pm

"Lipiec" is a Polish translation of July, so the template renders my translation from the languages.yaml file, as well as the standard date format.

I suspect the problem is in the following section of the blog.item.html.twig file:

<footer class="entry-footer">
        <span class="posted-on">
            <time class="entry-date published updated" datetime="{{ page.date|date(config.system.pages.dateformat.short) }}">{{ 'MONTHS_OF_THE_YEAR'|ta(page.date|date('n') - 1) }} {{ page.date|date(config.system.pages.dateformat.default) }}</time> 
        </span>

... but do not know Twig at all, so cannot say what's wrong.

It seems that this section renders a default date format if the short format is larger than some kind of a filter on MONTHS_OF_THE_YEAR? This does not make sense, so I am probably reading it in a wrong way.

Also, assuming it can be fixed easily... how do I put the updated class as inherited Twig code in a child theme? Do I copy the entire blog.item.html.twig file to the child theme folder, edit the problematic class and comment out the rest?

Hi @Perlkonig,

thank you!

Any advice how I can localize the full date manually - i.e., what to add to the languages.yaml file?

With my level of technical undesrtanding the Twig Extensions plugin seems more complex than manual localization - although thank you for pointing the plugin out!

It's super simple! The demo site shows you how.

Just install the plugin and then run your date through the localizeddate filter.

It's good to learn Twig eventually 🙂

It is simple :) I guess I needed a fresh look.

Also, this is covered in Twig Recipes - Displaying a Translated Month.

Your responses, the documentation and a couple of searches on Twig's date and localizeddate filters let me get it done.
