Description

Steps to replicate the issue (include links if applicable):

Visit https://sl.wikipedia.org/wiki/Glavna_stran while logged out (Private Browsing is sufficient).

What happens?:
There are great chances that the "Na današnji dan" ("On this day") box is displaying yesterday's date and template (sometimes even from two or three days ago). Purging the cache sometimes helps but often doesn't.

What should have happened instead?:
"Na današnji dan" should pick a template for today's date (as it usually does if logged in).

Other information (browser name/version, screenshots, etc.):
The issue has been first reported more than three years ago: Wikipedija:Pod lipo/Arhiv-2020#Na današnji dan?????

T119366 was closed recently.

Looking right now (20231119200000) gives a cached time from yesterday with a expiry of 1 hour, that looks like something is wrong.

en.wikipedia.org main page looks better in case of the timing as that is within the cache time

Is mw‐web.eqiad.main‐855fc47987‐6m22d a k8s thing and ParserCache is different there? Or is the html from vanish? Maybe Traffic is better here as some mediawiki specific project

X-Cache: cp3067 hit, cp3067 hit/53
X-Cache-Status: hit-front

Api gives another parser cache entry: https://sl.wikipedia.org/w/api.php?action=parse&page=Glavna_stran

Timing is good here as the cache entry is within the cache time

I can confirm that this issue persist, even after upgrading from {{LOCALDAY}}._{{LOCALMONTHNAME}}_{{LOCALYEAR}} to {{#timel:j. F Y}}.

I made further observations:

There is no issue on https://sl.wikipedia.org/wiki/Wikipedija:Glavna_stran/Prenova_2024_(z_ravnanjem_stolpcev), which uses exact same code as the main page (but is not visited as frequently).
Purging cache once does not suffice. One has to purge the site twice via https://sl.wikipedia.org/wiki/Glavna_stran?action=purge when logged out.

In T51803#8373568, I found {{#timel:j. F Y}} cannot schedule purges at all.
