How the converter stays accurate
How does this converter handle daylight saving?
Direct answer. It never hard-codes a fixed number of hours between two places. Instead it looks up each location’s actual UTC offset for the specific date and time you enter, using the IANA time-zone database.
That database is maintained continuously and ships inside every modern browser and phone, so it knows when British Summer Time, US Daylight Time, Australian summer time and dozens of other rules start and end. When a government changes the rules, a software update keeps the data current.
Key fact: Because offsets are looked up per date, the converter is correct even on the overlap days when the UK and another country are mid-transition.

Frequently asked questions
Is this time zone converter accurate?
Yes. It reads the IANA time-zone database built into your browser and operating system, which encodes every region’s daylight saving rules. That means the result is correct for any date you pick — past or future — and automatically handles the days when two countries change their clocks on different dates.
How do I convert UK time to another country?
Leave “From” set to London (UK), choose the destination in “To”, then set the date and time. The result shows the matching local time at the destination and the exact difference in hours.
Why does the time difference between two countries change during the year?
Because countries start and end daylight saving on different dates. For example, the United States moves its clocks forward two to three weeks before the UK does, so for a short window each spring the UK is only four hours ahead of New York instead of the usual five.
Can I share or bookmark a conversion?
