Dates Not Appearing Correctly On Pages
Question
Dates on my entries are missing elements such as the day of the week or the month, even though I'm using valid date tag formats.
Answer
Note: The information in this article applies only to versions below 3.2.
The default blog_language may not have been set (due to a bug in certain versions). (You may also see certain Use of uninitialized errors during rebuilds as a result of this bug.)
Go to Weblog Configuration > Preferences, and then select a setting for Language for Date Display.
Save this change and then rebuild your site.
