Translations / i18n

Languages and translations in Kimai are completely configurable. Read below how to add a new language and configure the output formats for date and time values.

Language files

We try to keep the number of language files small, in order to make it easier to identify the location of application messages and to unify the codebase.

  • If you add a new key, you have to add it at least in the en version as well (as english is the fallback language)
  • Its very likely that you want to edit the file messages as it holds 90% of our application translations

The files in translations/ as a quick overview:

  • about - the about screen with license information
  • daterangepicker - the daterange picker dialog to choose a timeframe in screens with data-tables
  • exceptions - error pages and exception handlers
  • flashmessages - success and error messages (alerts), whichwill be shown after submitting data
  • invoice-calculator - invoice calculator types (see Adding invoice calculator in developers-section)
  • invoice-numbergenerator - invoice calculator (see Adding invoice-number generator in developers-section)
  • invoice-renderer - holds translations of all invoice templates (read more)
  • messages - most of the visible application translations (like menu, buttons and forms)
  • pagerfanta - includes the translations for the pagination component below data-tables
  • plugins - the plugin screen
  • system-configuration - all system configuration, which can be changed through the UI
  • validators - related to violations/validation of submitted form data (or API calls)

Authentication screens

The authentication screens (login, registration, register account) are translated through the theme bundle which is used in Kimai. The bundle can be found here and the translations in this directory.

When you create a new translation, please open another PR there as well.

Adding a new language

As example I choose a new hypothetical language with the locale xx.

Add translations

Copy each translation from it’s english version translations/*.en.xliff and rename them to translations/*.xx.xliff.

Adjust the date and target-language attributes in the file header, as example for the new file exceptions.xx.xliff:

<file date="2018-08-01T20:00:00Z" source-language="en" target-language="xx" datatype="plaintext" original="exceptions.en.xliff">`

Configure locale formats

Adjust the file config/packages/kimai.yaml and add the language settings below the key kimai.languages:

        # copy all settings from 'en' and adjust them to your language
            date_time_type: 'yyyy-MM-dd HH:mm'
            date_type: 'yyyy-MM-dd'
            date: 'Y-m-d'
            date_time: 'm-d H:i'
            duration: '%%h:%%m h'

Register locale

Append the new locale in the file config/services.yaml at parameters.app_locales divided by a pipe:

    locale: en
    app_locales: en|de|ru|it|xx

Import frontend locales

Make sure the new locale is included in the frontend dependencies. For example Kimai includes moment.js, which ships its own translations. Kimai ONLY compiles the moment.js locales which are needed. Check and adapt the JS files in the assets/ directory, e.g. app.js:

const Moment = require('moment');
global.moment = Moment;



Date and time formats

Kimai uses the configurations in kimai.yaml to format the values in the frontend. It also uses the configurations to convert between javascript components (e.g. the date-picker) and the PHP backend, so they must create the same output.

12-hour format

Kimai uses 24 hour format by default. If you want to use the 12 hour am/pm format, you have to adjust the locale config at the key 24_hours like this:

            date_time_type: 'yyyy-MM-dd hh:mm a'
            date_type: 'yyyy-MM-dd'
            date: 'Y-m-d'
            date_time: 'm-d H:i'
            duration: '%%h:%%m h'
            time: 'h:i a'
            24_hours: false

Check for missing translations

You can search for missing keys by issuing this command (replace de with your locale):

bin/console debug:translation --only-missing de
