Laravel localization in Catalan Català

Locale codes

Set the base locale in config/app.php. For regional variants, Catalan commonly uses: ca_ES, ca_AD, ca_FR, ca_IT

// config/app.php
'locale' => 'ca',
'fallback_locale' => 'en',

// Or switch at runtime
App::setLocale('ca');

Plural rules: what Catalan actually needs

CLDR defines 3 cardinal categories for Catalan. The sample numbers below were computed by ICU for this exact locale:

Laravel's trans_choice() maps numbers to 2 pipe-separated forms for this locale:

// lang/ca/messages.php
'items' => ':count item|:count items'

// Usage
trans_choice('messages.items', $count, ['count' => $count]);

Try any number live in the pluralization tester.

Localized dates with Carbon

Real output for Catalan (ca locale), generated by Carbon for March 21, 2026:

$date = now()->locale('ca');

$date->translatedFormat('l, j F Y');
// "dissabte, 21 de març 2026"

$date->isoFormat('LLLL');
// "dissabte 21 de març de 2026 a les 14:30"

$date->isoFormat('L');
// "21/03/2026"

$date->subDays(3)->diffForHumans();
// "fa 3 mesos"

What to watch out for in Catalan

• Uses tu/vostè formal-informal distinction; agree on register before translating UI copy.
• Articles elide before vowels (l'usuari, l'hora), so avoid gluing raw articles to placeholders.
• Nouns are gendered (masculine/feminine) and adjectives agree in gender and number.
• Decimal comma with dot as thousands separator (1.234,56).

Framework strings already translated

Laravel's own validation, auth and pagination strings are maintained in Catalan by the open-source Laravel-Lang project (MIT). Install them, then manage your app's own strings live:

composer require laravel-lang/common --dev
php artisan lang:add ca
php artisan lang:update
