The Time Zone Converter helps you figure out what time it is in any part of the world relative to your local time or any other time zone. Select a source time zone, pick a time and date, and choose a destination time zone to see the converted time instantly. The tool covers 27 time zones from UTC-12 to UTC+12, including half-hour offsets like India (UTC+5:30) and Adelaide (UTC+9:30). A quick view section shows the converted time in six popular time zones at once, which is perfect for scheduling meetings with international teams. Whether you are coordinating calls with colleagues in London, Tokyo, and New York, planning travel across time zones, or just wondering what time it is where your friend lives, this tool gives you the answer in seconds.
Choose the time zone you are converting from using the From dropdown. Each zone shows the UTC offset and a recognizable city name, like UTC-05:00 (Eastern, EST).
Enter the time using the time picker and the date using the date selector. These default to the current time and date but can be changed to convert future or past times.
Choose the time zone you want to convert to using the To dropdown. The converted time and date appear instantly in the highlighted result box.
Review the Popular Time Zones section to see your selected time converted to PST, EST, GMT, IST, SGT, and JST simultaneously. Click Copy Result to grab the full conversion.
Time Zone Converter is the fastest way to convert between time zones online. Key advantages include 27 zone coverage, date and time selection, popular zone quick view, and clear time difference display.
UTC (Coordinated Universal Time) is the primary time standard used to regulate clocks worldwide. It replaced GMT (Greenwich Mean Time) as the international reference point. All time zones are defined as offsets from UTC: EST is UTC-5, IST is UTC+5:30, JST is UTC+9. UTC does not observe daylight saving time, making it the most stable reference for scheduling across time zones.
Eastern Standard Time (EST) is UTC-5 and Pacific Standard Time (PST) is UTC-8, so PST is 3 hours behind EST. When it is 3:00 PM in New York (EST), it is 12:00 PM (noon) in Los Angeles (PST). During daylight saving time, both zones shift forward by one hour but the 3-hour difference remains.
Countries like India (UTC+5:30), Iran (UTC+3:30), and parts of Australia (UTC+9:30) use half-hour offsets because their geographic position falls between two standard hourly zones. India chose UTC+5:30 as a compromise to cover its wide east-west span with a single time zone. Nepal goes even further with a UTC+5:45 offset.
Use the popular zones quick view to see your proposed meeting time in all major time zones at once. Look for a window where the time falls within normal working hours (roughly 9 AM to 6 PM) for all participants. A common approach for US-Europe meetings is morning Eastern time, which is afternoon in Europe. For US-Asia meetings, early morning Pacific time works as evening in Asia.
This tool uses fixed UTC offsets, which represent standard time for each zone. Daylight saving time (DST) shifts clocks forward by one hour in many regions during summer months. When DST is active, use the next offset (for example, use UTC-4 instead of UTC-5 for Eastern Daylight Time). DST schedules vary by country and change periodically.
