How to set date format for XWiki?

If you prefer a more detailed or readable format, you can customize it in: Administer XWiki → Content → Localization → Date / Time → Date Format

For instance, using the mask EEE MMM dd yyyy

where EEE - short day of the week (e.g., Thu). For the full version, use EEEE;

           MMM - short month name (Dec). For the full version, use MMMM;

           dd - day of the month;

           yyyy - year.

This will change the date representation to: Thu Dec 28 2023

You can also use other formats, such as:

• EEEE, dd MMM yyyy hh:mm a will be represented as Thursday, 28 Dec 2023 12:30 PM
• EEEE, yyyy/MMM/dd hh:mm z will be represented as Thursday, 2023/Dec/28 12:30 EET

Note: If your XWiki is multilingual, the date representation may vary. For instance, some languages display the short day of the week in lowercase.
