What Is Timezone Converter?

The Timezone Converter translates a specific date and time from one timezone to multiple other timezones simultaneously. Enter your source time, select its timezone, and instantly see the equivalent times across your chosen destination zones. The tool supports over 24 major timezones covering every UTC offset, and uses the browser's Intl.DateTimeFormat for accurate conversions including Daylight Saving Time adjustments. You can add and remove target timezones as needed, making it perfect for scheduling meetings, coordinating events, or working with international colleagues. Each conversion shows the time in 12-hour format, the full date, and the UTC offset.

Technical Guide

The converter works by first interpreting the input time in the source timezone context. It creates a reference date and uses Intl.DateTimeFormat with each target timezone to format the converted time. The formatToParts() method extracts individual components (hour, minute, day, month) for precise display. UTC offsets are determined per-timezone using the "shortOffset" timeZoneName option. The tool uses IANA timezone identifiers which are the international standard for timezone specification and are supported natively in all modern browsers. When the conversion crosses a date boundary (e.g., 11 PM in New York is 4 AM tomorrow in London), the full date is displayed to prevent confusion.
