Post date display


You can change it in /admin/customize/site_texts.

Search to 'YY will list the related date format strings.

In posts the date use this format: js.dates.tiny.date_year
Here you can change the date format 'YY to YYYY should be what you would like to achieve. :slightly_smiling_face:

Note: This will change the date format everywhere it is used in Discourse, not only in posts.
