Timezone Converter
Convert times between standard global timezone abbreviations with 24-hour and 12-hour display options.
Run tool
The Timezone Converter translates times between standard global timezone abbreviations. It uses fixed hourly offsets to recalculate any entered clock time for another region, making it easy to coordinate international meetings, plan travel itineraries, or track global sports events. You can enter any standard time in 24-hour or 12-hour notation alongside a source timezone abbreviation such as UTC, EST, PST, CET, or JST. The tool converts the time to your selected target zone and displays the result instantly in your preferred format. You can toggle between standard 24-hour display and 12-hour AM/PM notation. Supported timezone abbreviations include UTC, GMT, EST, CST, MST, PST, CET, EET, MSK, IST, BST, JST, AEST, AEDT, NZST, HST, AKST, ART, WAT, CAT, and EAT. Input abbreviations are case-insensitive. Conversions rely on fixed offset differences and wrap automatically across the 24-hour day.
Instructions
- Enter the time you want to convert in standard time notation.
- Type the source timezone abbreviation into the from field, such as UTC, PST, or GMT.
- Select the destination timezone from the target dropdown menu.
- Check or uncheck the 24-hour format option depending on whether you prefer military time or AM/PM notation.

Examples
- Converting 12:00 from EST to PST outputs 09:00 in 24-hour format.
