Trying to specify a date using the Date Picker within an Issue Screen generates the error, "The JIRA Calendar does not currently support your language.".


This error only affects certain users - it is not platform or browser-specific.


  1. The "Language Preferences" are set to an invalid option.  As an example, users may see a -1 for their Language:

JIRA Server applications can run the following query to see what users have an invalid Language set on their profiles. This query was written for PostgreSQL and may require changing depending on the DBMS used.

select u.user_key, PROPERTY_KEY, propertyvalue from propertyentry pe join app_user u on u.id = pe.entity_ID join propertystring ps on ps.id = pe.id and property_Key like '%locale%';

2. The "Language Preferences" are set to a language that is missing the calendar .js files JRA-30789 - Getting issue details... STATUS .



    1. Log into the instance with the affected user and view their Profile Settings (Click on the User's Profile Icon in the Upper Right > Profile).
    2. Click on the Edit Icon () next to Preferences.
    3. In this window, re-select your language from the Language Dropdown and click Update.
  1. .js files need to be added as mentioned in Translating JIRA (Translating the javascript calendar popup tool section)
