Timezone Converter
Convert date and time between 14 major world timezones instantly.
The Timezone Converter allows you to convert a specific date and time from one timezone to another across 14 major world timezones. Whether you are scheduling international meetings, coordinating with remote team members, planning travel across time zones, or figuring out when a live event airs in your local time, this tool gives you instant and accurate results.
The converter supports UTC and 13 widely used regional timezones covering the Americas, Europe, Asia, Australia, and the Pacific. It correctly handles daylight saving time (DST) transitions automatically, so you get accurate results year-round without needing to manually account for seasonal clock changes. For example, New York is UTC-5 during Eastern Standard Time but UTC-4 during Eastern Daylight Time, and the tool accounts for this based on the date you enter.
To use the tool, enter your date and time in YYYY-MM-DD HH:MM format, select the timezone you are converting from, and select the timezone you want to convert to. The tool parses your input, constructs a proper Date object in the source timezone, then uses the browser's built-in Intl.DateTimeFormat API with the timeZone option to format the result in the target timezone. This approach leverages the IANA timezone database built into modern browsers, ensuring accurate and up-to-date timezone offset data.
The output shows both the converted date and time and the UTC offsets for both timezones, making it easy to understand the relationship between them. All processing runs entirely in your browser with no data sent to any server.
