How the Time Zone Converter Works
This tool converts a date and time from one time zone into the equivalent date and time in another, using your device's built-in time zone database. Because it relies on standard IANA time zone identifiers such as Europe/London, America/New_York and Asia/Tokyo, daylight saving transitions are applied automatically wherever they exist.
The United Kingdom uses GMT (Greenwich Mean Time) in winter and BST (British Summer Time), one hour ahead of GMT, from late March to late October. It is a common mistake to assume the UK is always on GMT — the converter accounts for this automatically so results stay accurate all year round.
Because different countries move their clocks forward or back on different dates, the time difference between the UK and another location can vary slightly across the year, even for the same two cities. Always check the current result rather than relying on a fixed number of hours.
The converter is built for the UK's global communities and works for common searches such as UK time to Romania, UK time to India, UK time to Pakistan, UK time to Nigeria, UK time to Australia, UK time to New York, UK time to Dubai, UK time to Thailand and UK time to Jamaica — plus hundreds of other cities and countries worldwide.
Time Zone Converter FAQ
How do I convert UK time to another country?
Choose "UK / London" as your From location, search and select the destination city or country in the To field, enter a date and time, then read the converted time in the result box. You can also use the popular UK conversion buttons for common destinations.
Does the converter handle daylight saving time?
Yes. The converter uses your browser's built-in time zone data, which automatically accounts for daylight saving rules in both the origin and destination time zones, for any date you enter.
What is the default UK time zone?
The default From location is UK / London, using the Europe/London time zone. This automatically switches between GMT in winter and BST in summer.
Is London always on GMT?
No. London uses GMT (Greenwich Mean Time) in winter and BST (British Summer Time, GMT+1) from late March to late October. It is a common misconception that the UK is always on GMT.
Can I convert future dates and times?
Yes. Enter any future date and time in the "From" field and the converter will calculate the correct result, including any daylight saving changes expected to be in effect on that date.
What is the time difference between the UK and New York?
New York is typically 5 hours behind the UK, or 4 hours behind during periods when only one country has moved its clocks for daylight saving. Use the converter above for the exact current difference.
What is the time difference between the UK and Dubai?
Dubai does not observe daylight saving, so it is usually 4 hours ahead of UK GMT time and 3 hours ahead of UK BST time.
What is the time difference between the UK and Australia?
This varies by city and season because Australia's daylight saving dates differ from the UK's. Sydney is typically 9 hours ahead of the UK in UK winter, and around 10-11 hours ahead during parts of the year due to opposite-hemisphere daylight saving.
Can I search by country instead of city?
Yes. Type a country name such as Romania, India, Pakistan, Nigeria or Australia and the converter will suggest matching cities and time zones. You can also search by city, region, IANA time-zone name (for example Europe/Bucharest) or common abbreviations like IST, EST or AEST.
Why is my city not listed?
The converter loads the full list of time zones supported by your browser, so most locations are covered. Some smaller towns share the same time zone as a nearby major city, so search for your country or nearest large city instead.
What should I do if I cannot find my exact city?
Search for your country or nearest major city, which will share the same time zone. If you still cannot find it, use the Custom offset UTC options (UTC-12 through UTC+14) to convert by fixed offset.
Can I convert UK time to Romania?
Yes. Search for Romania or Bucharest and select Bucharest, Romania — Europe/Bucharest as your To location. Romania is normally 2 hours ahead of the UK, adjusting automatically for daylight saving.
Can I convert UK time to India?
Yes. Search for India, Mumbai, Delhi or IST and select an Indian city on Asia/Kolkata. India is 5 hours 30 minutes ahead of UK GMT and 4 hours 30 minutes ahead of UK BST, and does not observe daylight saving.
