Timezones are more than just a technical nuisance — they're a real threat to global businesses. Missed meetings, broken calendar exports, and daylight saving errors can cost you clients, trust, and time.
In this post, I’ll show you how I built a timezone conversion tool in Laravel that makes handling multiple timezones easy — even when your users span from Tokyo to Toronto.
Let’s dive in.
? The Problem Every Global Business Faces
Imagine this:
Sound familiar? You're not alone.
That’s why I built a simple but powerful Laravel timezone handler package — designed to solve these problems once and for all.
? Step 1: Get Started Fast With My Base Code
Why reinvent the wheel?
git clone
This repo includes:
You can start using it in minutes — no need to write everything from scratch.
Step 2: Use Magic Methods That Just Work
Convert Anywhere → UTC (Static Usage)
Perfect for background jobs or APIs where you don’t have a logged-in user:
$utcTime = UserTimeZoneHandler::toUtc('2023-01-01 14:00', 'Asia/Tokyo');
Instance Mode for Logged-In Users
For apps with user-specific timezones:
$handler = new UserTimeZoneHandler($user->timezone);
$localTime = $handler->toUserTimeZone($event->start_time);
Now every conversion respects the user’s current location — no matter where they are.
Step 3: Don’t Make My Carbon Mistake
I wasted hours debugging a failing test until I realized:
use Illuminate\Support\Carbon;
Not Carbon\Carbon.
It’s an easy fix — but one that saves you from weird date parsing bugs later.
?️ Step 4: Customize It for Your Product
Need to support Zoom, Google Calendar, or your own custom export format?
Just add a new formatter:
'zoom' => $utcTime->format('Ymd\THis\Z')
Want to convert working hours between two offices?
$converted = UserTimeZoneHandler::convertTimeRanges(
$businessHours,
'America/Chicago',
'Europe/Paris'
);
This makes it perfect for:
Run the server:
php artisan serve
Then visit:
Try converting dates across different timezones and see how it handles:
You’ll be amazed how smoothly it works.
Why This Matters for Your Business
This isn’t just a developer tool — it’s a business enabler.
By handling timezones correctly, you ensure:
And best of all?
It’s open-source, so you can clone it, tweak it, and make it your own — without bloating your app with heavy libraries.

Imagine this:
Or worse:
- Calendar exports show incorrect times
- Daylight Saving Time changes break everything twice a year
- Manual conversions lead to bugs, missed events, and angry customers
Sound familiar? You're not alone.
That’s why I built a simple but powerful Laravel timezone handler package — designed to solve these problems once and for all.
? Step 1: Get Started Fast With My Base Code
Why reinvent the wheel?
git clone
This repo includes:
- A pre-built UserTimeZoneHandler class
- Working demo UI (/timezone-converter)
- Unit tests (for DST and edge cases)
- Ready-to-use methods for both static and instance-based conversions
You can start using it in minutes — no need to write everything from scratch.
Step 2: Use Magic Methods That Just WorkConvert Anywhere → UTC (Static Usage)

$localTime = $handler->toUserTimeZone($event->start_time);

Always use:
use Illuminate\Support\Carbon;
Not Carbon\Carbon.

?️ Step 4: Customize It for Your Product
Need to support Zoom, Google Calendar, or your own custom export format?
Just add a new formatter:
'zoom' => $utcTime->format('Ymd\THis\Z')
Want to convert working hours between two offices?
$converted = UserTimeZoneHandler::convertTimeRanges(
$businessHours,
'America/Chicago',
'Europe/Paris'
);
This makes it perfect for:
- Scheduling tools
- Remote team planners
- Booking systems
- Customer-facing dashboards
Run the server:
php artisan serve
Then visit:
Try converting dates across different timezones and see how it handles:
- DST changes
- Custom formats
- Multiple inputs
You’ll be amazed how smoothly it works.
Why This Matters for Your BusinessThis isn’t just a developer tool — it’s a business enabler.
By handling timezones correctly, you ensure:
- Fewer customer complaints about scheduling
- Accurate calendar integrations
- Better international UX
- Reduced support tickets during DST changes
And best of all?
It’s open-source, so you can clone it, tweak it, and make it your own — without bloating your app with heavy libraries.
