Common Time Zone Conversions
The most frequently converted pairs include EST to GMT (New York to London, +5 hours), PST to IST (Los Angeles to India, +13.5 hours), and JST to EST (Tokyo to New York, −14 hours). Business meetings across continents often need conversions between US Eastern, Central European, and Asia Pacific time zones. The converter handles all of these including half-hour offsets like India (UTC+5:30) and Nepal (UTC+5:45). For scheduling tips, read our blog post on scheduling meetings across time zones.

Understanding DST (Daylight Saving Time)
Daylight saving time shifts clocks forward by one hour in spring and back in autumn. Not all countries observe DST, and those that do change on different dates. This means the offset between two cities can vary throughout the year. For example, New York to London is normally +5 hours, but during the weeks when only one has switched, it can be +4 or +6. Our converter accounts for this automatically by using the browser's Intl API, which has up-to-date DST rules for every timezone.
Tips for Accurate Time Conversions
- Always set the date — DST means offsets change throughout the year. Set the correct date for an accurate conversion.
- Use Current Time — For right-now conversions, the button fills in the exact current date and time in your timezone.
- Check the world clock — The live clock below confirms current times in major cities at a glance.
- Watch for date changes — Converting across many hours can change the date. The result shows the full date for clarity.
- Half-hour zones — Countries like India, Iran, and Nepal have non-whole-hour offsets. The converter handles these correctly.
Frequently Asked Questions
How accurate is the DST handling?
The converter uses your browser's built-in Intl API, which follows the IANA timezone database. This is the same source used by operating systems and is regularly updated.
Can I convert future dates?
Yes. Set any future date and the converter will apply the correct DST rules for that date, as far as they are currently known.
Why is my local timezone wrong?
The tool reads your browser's timezone setting. If it's incorrect, check your operating system's date and time settings.
Does the world clock show seconds?
Yes. All six city clocks update every second with hours, minutes, and seconds in 12-hour format.
Can I add more cities to the world clock?
The current version shows six major cities. You can convert any additional city using the converter above.
