How to Convert Time Zones
Converting time between zones is simple with our tool: select the city or time zone you're converting from, enter the time, and select where you're converting to. The result updates instantly showing the equivalent time, date, and how many hours ahead or behind the destination is.
What Are Time Zones?
Time zones are regions of the Earth that observe the same standard time. The world is divided into 24 primary time zones, each roughly 15 degrees of longitude wide. The reference point is Coordinated Universal Time (UTC), formerly known as Greenwich Mean Time (GMT). Time zones are expressed as offsets from UTC — for example, Eastern Standard Time (EST) is UTC-5, meaning it's 5 hours behind UTC.
Daylight Saving Time
Many regions observe Daylight Saving Time (DST), shifting clocks forward by one hour in spring and back in fall. This means time differences between cities can change throughout the year. For example, the difference between New York and London is 5 hours during winter but only 4 hours during summer when both observe DST. Our converter automatically accounts for DST based on the current date.
UTC vs. GMT
UTC (Coordinated Universal Time) and GMT (Greenwich Mean Time) are often used interchangeably, but they're slightly different. GMT is a time zone used by some countries, while UTC is the time standard that all time zones are defined relative to. For everyday purposes, they represent the same time.
Common Time Zone Abbreviations
EST (Eastern Standard Time, UTC-5), CST (Central Standard Time, UTC-6), MST (Mountain Standard Time, UTC-7), PST (Pacific Standard Time, UTC-8), GMT/UTC (Greenwich Mean Time, UTC+0), CET (Central European Time, UTC+1), IST (India Standard Time, UTC+5:30), JST (Japan Standard Time, UTC+9), AEST (Australian Eastern Standard Time, UTC+10).
Tips for Working Across Time Zones
When scheduling meetings across time zones, try to find overlapping business hours. Generally, late morning for the western participants and late afternoon for eastern participants works well. Always specify the time zone when sharing meeting times, and use tools like this converter to avoid confusion. Consider using UTC as a neutral reference when coordinating with many zones.

Time Zone Details for this location
Accurate timezone data is critical for scheduling, travel planning, and coordinating across regions. Our converter uses the IANA Time Zone Database, the same authoritative source used by every major operating system and web platform, to ensure the times displayed are consistent with what you see on your devices. Daylight saving transitions are reflected automatically based on the current date.
When planning calls or meetings involving this location, account for the possibility that DST transitions happen on different dates in different countries. A city pair that is normally 8 hours apart might temporarily be 7 or 9 hours apart during the weeks when one location has transitioned but the other has not. Our converter always shows the current correct offset.
For frequent timezone conversions, bookmark this page for instant access. The conversion updates automatically each time you visit, reflecting any changes in DST status or timezone rules since your last visit. You can also use our meeting planner tool to find overlapping business hours across multiple zones simultaneously.
