The pages listed to the left provide guidelines for translation of CLDR strings. For an overview of the tools, please read the Survey Tool Guide before starting.

Data stability

Please be mindful of data stability by carefully reviewing previously Approved data. When it's clearly incorrect, it should be changed — but for data stability, don't change the field it is already acceptable (even if not optimal). When you have an evidence of a variant being much better and in customary use than the existing Approved data, use the Forum to bring up discussions and gain consensus to change Approved values.

Current Survey Tool stage: CLOSED

The survey tool is closed for data submissions. Please look for the Alpha release mid-February. For full schedule, please refer to Milestone Schedule in the left navigation.

The v35 submission has been a limited scope, Please see Submission (Limited) for more details before starting.

The following languages have moved coverage levels: 
  • Somali (so) and Javanese (jv) have moved up to Modern coverage.
  • Cebuano (ceb), Hausa (ha), Igbo (ig), Yoruba (yo) have moved to Basic coverage.

What's new in this release

TBD: Will be updated for v36.

Translation Guides

Sections of the translation guides that have been updated in preparation for this contribution period.
  1. Timezone names and Territory names often share the same term. A list of overlapping data between Timezone and Territory names are available in this public spreadsheet. Use this spreadsheet as a reference when working on Timezone names, and bring consistency for Timezone names where they are also found in Territory names.[Same workaround as v34]
  2. Emoji names and keyword translation guide has been updated. If you are new to emoji names and keywords or as a refresher, please review this page before starting on Emoji names and keywords. 
  3. Country/Region (Territory) Names for clarity in areas where we have seen confusion.
  4. For items that do not work in your language, please don't simply accept to use the English. Find a solution that works for your language. For example, if your language doesn't have a concept of "quarters", use a translation that describes the concept "three-month period" rather than “quarter-of-a-year”.
    1. Pashto: There will be several missing data in the Date & Time formats including "quarters" (see Ticket #11565). Please provide an appropriate translations for the missing data.
  5. Typographic Names. Added guidance on collision errors.

Known Issues

Please review this list before getting started to avoid creating duplicate tickets. This list will be updated as fixes are made available in production. If you hit a problem, please file a ticket.

TBD: Will be updated for v36.

    Survey Tool Stages 


    The survey tool is live and all data that you enter will be saved and used. You can start work, but there may be additional fixes during this period. So the tool may be taken down for updates more frequently than after we exit Shakedown. During Shakedown, your participation in looking for issues with the Survey tool is essential. If you find any problems in the tool, please file a ticket.

    Submission (Limited)

    Make sure your coverage level is set correctly at the top of the page.

    For a limited-submission release, the Survey Tool will only let you add or vote in certain rows. What you can do depends on your locale:
    1. Newly targeted locales: proceed with Submission (General). 
    2. Other targeted locales: proceed with Submission (General), but start with the Dashboard step and focus on Errors*, Missing†, and English Changed.
    3. Other locales: go to the Dashboard and deal with any Errors*.
    * Note that if the committee finds systematic errors in data, new tests can be added during the submission period, resulting in new Errors.
    † Among the Missing for v35 are new items for translation: Emoji 12, generic calendar date-intervals, more measurement units, a narrow list format (“&” in English), and a few others. (On the Dashboard, New means winning values that have changed since the last release.)

    If you want to know which locales are in which categories, see Targeted Locales.

    Submission (General)

    Make sure your coverage level is set correctly at the top of the page.
    For new locales or ones where the goal is to increase the level, it is best to proceed page-by-page starting with the Core Data section. At the top of each page you can see the number of items open on the page. Then scan down the page to see all the places where you need to vote (including adding items). Some 

    Then please focus on the Dashboard view, first getting all Missing† items entered, and then addressing any remaining Errorsand reviewing the English Changed (fixing your language if necessary). 

    * Note that if the committee finds systematic errors in data, new tests can be added during the submission period, resulting in new Errors.
    † Among the Missing are are new items for translation(On the DashboardNew means winning values that have changed since the last release.)

    If you are working in a sub-locales (such as fr_CA), coordinate with others on the Forum to work on each section after it is are done in the main locale (fr). That way you avoid additional work and gratuitous differences. See voting for inheritance vs. hard votes in Survey Tool guide


    All contributors are encourage to move their focus to the Dashboard view, and:
    1. Resolve all of the Errors.
    2. Review all items in the Forums that don't show consensus yet, and try to resolve them by posting relevant information.
    3. Consider other's opinions, by reviewing the Disputed and the Losing. See guidelines for handling Disputed and Losing.
    4. Review the items that are Flagged for TC and provide comments if you have information that should be considered.  
    To see the Flagged items, go to the Gear dropdown, under Forum see Flagged items:


    The vetting is done, and further work is being done by the CLDR committee to resolve problems. You should periodically take a couple of minutes to check your Forums to see if there are any questions about language-specific items that came up.

    Newly targeted locales:
