Tool Description

Global Timezone Converter is a tool that helps you quickly and accurately calculate and compare times across the world. Whether you're scheduling international meetings, collaborating with remote teams, or planning travel, this tool provides clear and intuitive time references.

Core Features：

Real-time Conversion: Simply select a source date, time, and timezone, and the tool will instantly calculate the corresponding time in all your added target timezones.
Complete Timezone Support: This tool supports all standard **IANA timezones** (e.g., `America/Los_Angeles`, `Asia/Shanghai`), ensuring accurate timezone calculations and automatically handling complex Daylight Saving Time (DST) rules.
Multiple Timezone Comparison: You can add any number of target timezones for synchronized comparison, making it easy to find the best meeting time for all participants.
Automatic Local Timezone Detection: The tool automatically detects your browser's local timezone and uses it as the default source timezone, allowing you to get started quickly.

Pro Tip: Why use IANA timezones?

Timezone abbreviations like `CST` are ambiguous—they can refer to Central Standard Time (US), China Standard Time, or Cuba Standard Time. In contrast, IANA timezone names (e.g., `America/Chicago`, `Asia/Shanghai`) are globally unique and precisely define the time rules for a specific geographic region, making them the preferred choice for all professional applications.
