Convert time between any two time zones around the world.
The Time Zone Converter helps you coordinate across the globe by translating any local time into a different UTC/GMT offset.
Target Time = UTC + OffsetIn our hyper-connected world, coordinating across continents is a daily task. Whether you are scheduling a business meeting in London or catching a live stream from Tokyo, understanding time zones is essential.
UTC (Coordinated Universal Time) is the primary time standard by which the world regulates clocks and time. It is not a time zone itself. GMT (Greenwich Mean Time) is a time zone used in some European and African countries. For most practical purposes, they are identical in time value.
The trickiest part of time zone conversion is DST. Not all countries observe it, and those that do often change their clocks on different dates. When converting, always double-check if your target offset includes an extra hour for summer time.
All time zones are measured as offsets from the Prime Meridian in Greenwich, London (0° longitude). Bases jump in 15-degree increments of longitude to creates 24 standard one-hour zones.
If it is 10:00 AM in New York (UTC-5) and you want to know the time in Berlin (UTC+1), the target offset is +1. Result: 4:00 PM.
