What is Time Zone Converter?
A time zone converter helps you translate a specific time from one time zone to another. Essential for remote workers, international teams, travelers, and anyone coordinating across regions.
Our converter supports 28+ major time zones with automatic DST handling, live world clocks for 8 major cities, the ability to add multiple target zones for meeting planning, and a clean, instant display of converted times.
How It Works
Select a source time zone and set the date and time (or use "Live Now" for current time). Add one or more target time zones. The converter instantly shows the equivalent time in each zone, including DST adjustments and day-change indicators. World clocks update every second.
Formula
Target Time = Source Time − Source UTC Offset + Target UTC Offset Example: 2pm EST (UTC-5) to GMT (UTC+0) = 2pm + 5h = 7pm GMT
Formula Explained
Time zone conversion works by first converting the source time to UTC (by subtracting the source offset), then converting from UTC to the target zone (by adding the target offset). DST complicates this because offsets change seasonally. Our converter uses the browser's Intl API which automatically handles DST for all supported zones.
Example
Convert 2:00 PM New York (EST) to other zones: Los Angeles (PST): 11:00 AM (same day) London (GMT): 7:00 PM (same day) Paris (CET): 8:00 PM (same day) Tokyo (JST): 4:00 AM (next day) Sydney (AEDT): 6:00 AM (next day)
