Additional Information

closes issue issue: DEFAULT_LOCALE does not affect date display, fixed at MM/DD/YYYY #19020
this PR addresses date formatting issues in two frequently used chat search modals:
main chat search modal.
-Admin Settings -> User Chat Search modal.
The changes ensure that both use DEFAULT_LOCALE for date formatting. Further investigation will identify and correct any additional occurrences of improper date formatting in future PRs, once this solution is validated

Screenshots or Videos

The following have DEFAULT_LOCALE='en-gb'

👋 Welcome and Thank You for Contributing!

We appreciate you taking the time to submit a pull request to Open WebUI!

⚠️ Important: Testing Requirements

We've recently seen an increase in PRs that have significant issues:

PRs that don't actually fix the bug they claim to fix
PRs that don't implement the feature they describe
PRs that break existing functionality
PRs that are clearly AI-generated without proper testing being done by the author
PRs that simply don't work as intended

These untested PRs consume significant time from maintainers and volunteer contributors who review and test PRs in their free time.
Time that could be spent testing other PRs or improving Open WebUI in other ways.

Before marking your PR as "Ready for Review":

Please explicitly confirm:

✅ You have personally tested ALL changes in this PR
✅ How you tested it (specific steps you took to verify it works)
✅ Visual evidence where applicable (screenshots or videos showing the feature/fix working) - if applicable to your specific PR

If you're not certain your PR works exactly as intended, please leave it in DRAFT mode until you've thoroughly tested it.

Thank you for helping us maintain quality and respecting the time of our community! 🙏

I've tested this PR locally, but it doesn't appear to be working as expected on my end from what I can tell.

I switched from the dev branch to this PR's branch using GitHub Desktop, linked to my local Open WebUI repo. Before starting the frontend and backend for Open WebUI in VSCode, I deleted the webui.db file to ensure a clean slate. I then set DEFAULT_LOCALE='en-gb' as an environment variable in the .env file and started both the frontend and backend in separate VSCode terminals. Despite this, the date format in the chat search modal remained unchanged.

I haven’t tested the user-specific chat search modal, as I only have a superadmin account set up. Without additional users, there are no existing chats to test with. Imported chats would all show today’s date, making that test case unreliable.

 									<div class="basis-2/5 flex items-center justify-end">
 										<div class="hidden sm:flex text-gray-500 dark:text-gray-400 text-xs">

Perhaps it's better to use the implementation you can find in UserMessage component?

Perhaps it's better to use the implementation you can find in UserMessage component?

I did take a look at that, the formatDate() util called in UserMessage only returns date in DD/MM/YY at mm/hh format which is different than what is currently in the SearchChats/ChatsModal components (i.e. Today, Yesterday, Last Tuesday, DD/MM/YYYY, etc.) so I modified the .calendar() usage to override the default dayjs behavior

@silentoplayz looks like this might be a separate bug where we're not actually loading the DEFAULT_LOCALE value at all. My suspicion is that we're using the language. When you have time could you try pulling my latest commit and setting the language to say en-gb and seeing if chat searches show up with the DD/MM/YYYY locale?

I pulled the latest commit from your PR and didn't see any changes from the set DEFAULT_LOCALE env var for en-gb.

As you suggested, setting the language in the UI to English (GB) results in chat searches showing up with the DD/MM/YYY locale.

Thanks!

Thanks for confirming @silentoplayz
My latest commit should fix the issue of not setting dayjs with the DEFAULT_LOCALE value from backend
Can you please try the following:

Settings -> Change language back to English (US). Search modal should show MM/DD/YYYY format again.
Go to Developer Tools -> Application -> Local storage -> delete the key/value pair for locale

3. Now set env var DEFAULT_LOCALE=en-gb 4. Restart backend

(edit: looks like Tim merged this as I typed this 😅) appreciate the testing!

I followed the provided steps and all is good now with DEFAULT_LOCALE='en-gb' set as an environment variable!

Benefits: - Handles buckets with any number of indexes (no pagination needed) - ~8x faster (0.19s vs 1.53s in testing) - Proper exception handling for ResourceNotFoundException - Scales to millions of indexes * Update s3vector.py Unneeded exception handling removed to match original OWUI code * feat: Add adjustable text size setting to interface (open-webui#19186) * Add adjustable text size setting to interface Introduces a user-configurable text size (scale) setting, accessible via a slider in the interface settings. Updates CSS and Sidebar chat item components to respect the new --app-text-scale variable, and persists the setting in the store. Adds related i18n strings and ensures the text scale is applied globally and clamped to allowed values. * Refactor text scale logic into utility module Moved all text scale related constants and functions from components and stores into a new utility module (src/lib/utils/text-scale.ts). Updated imports and usage in Interface.svelte and index.ts to use the new module, improving code organization and reusability. * Adjust sidebar chat scaling without extra classes keep sidebar markup using existing Tailwind utility classes so chat items render identically pre-feature move all text-scale sizing into app.css under the #sidebar-chat-item selectors change the root font-size multiplier to use 1rem instead of an explicit 16px so browser/user preferences propagate * Update Switch.svelte Adjust toggles from fixed pixel to rem to scale with the text size * Update Interface.svelte Updated label from 'Text Scale' to 'UI Scale'.

Hello everyone. Can you tell me a bit more concerning the DEFAULT_LOCAL .
I have concerns concerning this variables, which is involve in this issue : #16476
It looks like this variable is just used for for web searches with bing, nowhere else. And this environment variable is NOT linked in the UI. This is NOT the language you can set in the settings (this one does change language / internationalization for the UI). Weird is that the documentation may suggest that DEFAULT_LOCALE does more.

Can you explain ?

Hello everyone. Can you tell me a bit more concerning the DEFAULT_LOCAL . I have concerns concerning this variables, which is involve in this issue : #16476 It looks like this variable is just used for for web searches with bing, nowhere else. And this environment variable is NOT linked in the UI. This is NOT the language you can set in the settings (this one does change language / internationalization for the UI). Weird is that the documentation may suggest that DEFAULT_LOCALE does more.

Can you explain ?

DEFAULT_LOCALE is used in three places inside the application:

Bing Search localization
It is sent as the mkt parameter to Bing so that the web-search results match the chosen market/language.
Code: backend/open_webui/routers/retrieval.py
Chat-search date formatting
When you search through old chats the timestamps are rendered with Intl.DateTimeFormat, using DEFAULT_LOCALE as the locale.
This gives you the correct order (DD/MM vs MM/DD) and separators for that region.
(Introduced in the PR that added the chat-search feature.)
First-visit UI language (fallback)
If a visitor has never chosen a language (nothing in localStorage.locale) and the browser’s language can’t be matched, the UI falls back to DEFAULT_LOCALE.
Code: src/routes/+layout.svelte → backendConfig.default_locale
Code: src/lib/i18n/index.ts (same fallback path)

In short, DEFAULT_LOCALE is not just for Bing—it also controls the default date format you see in search results and the language the interface starts with for new users.
