Steps to reproduce the problem

1. Change the language to Korean
2. open the any posts
   example - https://muri.network/deck/@TEA_FOP/111000303520826018

Expected behaviour

two digit (2023년 09월 07일 or 2023-09-07) (%Y-%m-%d) or single digit (2023년 9월 7일)

Actual behaviour

mixed one digit & two digit (2023년 9월 07일 or 2023-9-07) (%Y-%f-%d)

The Korean translation only calls %f in two cases, and does not write %f and %d together.

These translation strings are for server-side-rendered content, which is not the case in your screenshot.

As far as I can tell, the code responsible for your screenshot is:

mastodon/app/javascript/mastodon/features/status/components/detailed_status.jsx

Line 326 in 8a9d7ae

<FormattedDate value={new Date(status.get('created_at'))} hour12={false} year='numeric' month='short' day='2-digit' hour='2-digit' minute='2-digit' />

It appears it sets numeric for year, short for month (which in English locale is not numeric), and 2-digit for day. So I suppose the issue is the short style for months in Korean is numeric?

Hi ClearlyClaire,

Thanks for the feedback.

If we write X year Y month Z day or month name, we need to hide the zeros in the number of days. Only Mastodon uses two digits, including zeros, in its detailed date format.

Unless our translation project can control the date formatting of posts, we'll have to leave the zeros out. It's a minor change, so even if it's an afterthought, it seems like something that should be fixed at someday.

So many thanks.

Yeah, you're right, using 2-digits for days is a weird choice regardless of the locale!
