Timezone Converter: Convert Time Between Any Timezones

Working across timezones is a daily reality for remote teams, international businesses, and global travelers. Our free Timezone Converter uses the browser’s Intl API for accurate conversion with automatic daylight saving time handling.

How to Use the Converter

Select source timezone: Choose where the time is coming from
Select target timezone: Choose where you want to convert to
Enter date and time: Set the specific date and time to convert
See the result: The converted time appears instantly with offset information

Quick preset buttons for UTC, EST, PST, GMT, JST, and CST make common conversions faster.

Why Accurate Conversion Matters

Timezone conversion is trickier than simple offset math. Daylight saving time changes the offset twice a year, and different regions switch on different dates. Some regions don’t observe DST at all. Our converter uses the Intl.DateTimeFormat API, which handles all these edge cases using the IANA timezone database.

Common Use Cases

Remote team meetings: Find times that work across offices in different countries
International calls: Schedule calls with clients or partners abroad
Travel planning: Know what time you’ll arrive in local time
Event planning: Set deadlines and launch times for global audiences
Development: Convert timestamps in logs and databases

Tips for Timezone Management

Use UTC as a common reference point for distributed teams
Include timezone abbreviations when sharing times (e.g., “3 PM EST”)
Remember that DST shifts can change your usual time difference
Consider the International Date Line — crossing it changes the date
