Free Time Zone Converter
Convert a local date and time between cities around the world. Daylight saving rules are applied by your browser’s time zone database.
Note: The selected time is interpreted as a local clock time in the source zone. Times that are ambiguous or do not exist during daylight saving transitions may need extra verification.
Convert time between different time zones with our free Time Zone Converter. Whether you are scheduling an international meeting, planning a trip, working with remote teams, or contacting friends abroad, understanding time differences can help you avoid confusion.
What Is a Time Zone Converter?
A time zone converter is an online tool that helps you determine the corresponding time in another location. It accounts for differences between time zones and, when properly configured, daylight saving time changes.
For example, you can use a time zone converter to compare working hours in New York, London, Dhaka, and Tokyo.
How to Use a Time Zone Converter
- Select the date and time you want to convert.
- Choose the starting time zone.
- Select the destination time zone.
- Click the Convert button to view the corresponding local time.

Why Are Time Zones Different?
Earth rotates on its axis, so different places experience daylight at different times. To organize clocks and schedules, the world uses time zones with different offsets from Coordinated Universal Time (UTC).
Some locations also adjust their clocks seasonally for daylight saving time. These changes mean that the time difference between two cities can vary throughout the year.
Common Time Zone Abbreviations
- UTC: Coordinated Universal Time, the main reference for global timekeeping.
- GMT: Greenwich Mean Time, often used as a time reference.
- EST: Eastern Standard Time, used in parts of North America during standard time.
- EDT: Eastern Daylight Time, used in parts of North America during daylight saving time.
- CET: Central European Time, used in parts of Europe during standard time.
- BST: British Summer Time, used in the United Kingdom during daylight saving time.
- BJT: Bangladesh Standard Time is UTC+6; it is commonly referred to as Bangladesh Standard Time rather than BJT.
Time zone abbreviations can have different meanings, so selecting a city or named time zone is usually more reliable than relying on an abbreviation alone.
