Convert time between different timezones
Our free timezone converter instantly converts time between different time zones worldwide. Essential for remote teams, international business, travelers, and anyone coordinating across time zones. See current times in multiple zones at a glance.
Using our timezone converter is simple. Enter the time you want to convert using the time picker. Select the source timezone (where the time is from) and target timezone (where you want to convert it to). Click Convert to see the equivalent time in your target timezone. The tool displays current times in major world time zones for quick reference. Perfect for scheduling international meetings, coordinating with remote team members, or planning calls across continents.
The world is divided into 24 main time zones, each roughly 15 degrees of longitude apart, corresponding to one hour of time difference. Time zones are based on Coordinated Universal Time (UTC), which serves as the global time standard. For example, EST (Eastern Standard Time) is UTC-5, meaning it's 5 hours behind UTC. Time zones help synchronize activities across the globe while maintaining a logical relationship to solar time. Some regions use half-hour or 45-minute offsets (like India at UTC+5:30), making time zone calculations more complex than simple hour differences.
Many regions observe Daylight Saving Time (DST), moving clocks forward one hour in spring and back in fall. This practice aims to make better use of daylight during longer summer days. However, not all countries or regions observe DST, and those that do may change on different dates. For example, the US changes in March and November, while Europe changes in March and October. Some countries like Japan, China, and India don't use DST at all. These variations make timezone conversions tricky - always verify whether DST applies to your specific dates.
Remote workers schedule meetings with colleagues across different time zones to find mutually convenient times. International businesses coordinate conference calls between offices in New York, London, Tokyo, and Sydney. Travelers plan phone calls home without waking family members at 3 AM. Customer support teams manage shift handoffs across global offices. Event organizers schedule webinars accessible to international audiences. Online gamers coordinate raid times with team members worldwide. Stock traders track market hours across different exchanges. Project managers coordinate deliverables with offshore development teams. Families with members living abroad find good times to video call.
Americas: EST/EDT (New York), CST/CDT (Chicago), MST/MDT (Denver), PST/PDT (Los Angeles) for the US. Canada follows similar zones. South America uses various zones with Brazil spanning three zones.
Europe/Africa: GMT/BST (London), CET/CEST (Paris, Berlin), EET/EEST (Athens, Cairo). Africa has several zones from UTC+0 to UTC+3.
Asia/Pacific: IST (India), CST (China, no DST), JST (Japan), AEDT/AEST (Sydney), NZDT/NZST (Auckland). Many Asian countries don't use DST.
When scheduling international meetings, use timezone-aware calendar tools like Google Calendar or Outlook that automatically adjust times. Always specify the timezone when communicating times - "3 PM EST" rather than just "3 PM". Consider using UTC for unambiguous global coordination, especially in technical contexts. Be aware of DST transitions that can shift meeting times by an hour. Use phrases like "Are you available at 2 PM your time?" to avoid confusion. Keep a world clock showing your frequently-used time zones. Remember that flying across time zones causes jet lag, so schedule important meetings accordingly when traveling.
The International Date Line roughly follows the 180° meridian in the Pacific Ocean. Crossing this line changes the date by one day. Traveling west across the line (Asia to Americas) adds a day, while traveling east (Americas to Asia) subtracts a day. This can create confusing situations - you could leave Sydney on Monday and arrive in Los Angeles the previous Sunday! The date line zigzags to accommodate political boundaries, keeping countries on one side or the other rather than splitting them across two dates.
All timezone conversions happen locally in your browser using built-in JavaScript timezone data. No personal information or time data is sent to servers. The tool accounts for DST where applicable and provides accurate conversions based on current timezone rules.
