About World Time Sync

Making time zone coordination effortless for everyone, everywhere.

Our Story

World Time Sync was born from a simple frustration: existing world clock tools were either too complicated, too slow, or too limited. In 2024, we set out to build something better — a fast, comprehensive, and completely free world clock that anyone could use without creating an account or navigating cluttered interfaces.

What started as a simple time checker has grown into a full platform serving hundreds of thousands of users worldwide. Today, World Time Sync provides accurate time information for 682 cities across every continent, along with a meeting planner, embeddable widget, and WordPress plugin.

Our Mission

We believe that understanding time across borders should be effortless. Whether you're a remote worker coordinating with teammates in Tokyo, a traveler planning your next flight, or a business owner scheduling calls with international clients — you deserve a tool that just works.

Our mission is to provide the most accurate, comprehensive, and user-friendly time zone tools on the internet, completely free of charge. No paywalls. No premium tiers. No data harvesting. Just reliable time information when you need it.

What We've Built

How We Ensure Accuracy

Time zone data is surprisingly complex. Countries change their DST rules, new time zones are created, and political decisions can shift a region's UTC offset overnight. Here's how we stay accurate:

• IANA Time Zone Database: We use the industry-standard IANA database (also known as the Olson database), which is maintained by volunteers and updated multiple times per year.
• Real-time calculation: All times are calculated client-side using your device's clock, ensuring sub-second accuracy.
• Automatic DST handling: Daylight saving transitions are handled automatically — you never need to manually adjust.
• Regular updates: Our city database is reviewed and updated regularly to reflect geopolitical changes.

Who Uses World Time Sync?

Our tools are used by a diverse global audience:

• Remote teams coordinating daily standups across 3+ time zones
• Travelers checking local times before landing in a new city
• Event organizers scheduling webinars for global audiences
• Developers integrating our widget into their applications
• Students attending online classes in different time zones
• Journalists coordinating interviews across continents
• Traders tracking market hours in New York, London, Tokyo, and Sydney
