Laravel localization in Italian Italiano

Locale codes

Set the base locale in config/app.php. For regional variants, Italian commonly uses: it_IT, it_CH

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

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

Plural rules: what Italian actually needs

CLDR defines 3 cardinal categories for Italian. 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/it/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 Italian (it locale), generated by Carbon for March 21, 2026:

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

$date->translatedFormat('l, j F Y');
// "sabato, 21 marzo 2026"

$date->isoFormat('LLLL');
// "sabato 21 marzo 2026 14:30"

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

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

What to watch out for in Italian

• Tu/Lei formal-informal distinction; decide on register before translating UI copy.
• Nouns are gendered and articles change form by sound (il/lo/la/l'), making article + placeholder patterns fragile.
• Adjectives agree in gender and number with nouns.
• 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 Italian 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 it
php artisan lang:update
