London to Tokyo time difference
Japan stays on UTC+9 all year, so the distance to London is 9 hours in winter and 8 hours once British Summer Time begins. A London morning lands in the Tokyo evening, which makes the very start of the UK day the natural place to meet.
Working hours: when London and Tokyo overlap
A standard 09:00–17:00 working day in London and the same hours in Tokyo do not overlap at all at the moment — the gap between the two cities is simply too wide. In practice this pairing needs someone to take an early-morning or evening call, or an asynchronous handover instead of a live meeting. Use the timeline above to find the least unsociable hour for both sides.

Daylight saving between London and Tokyo
Tokyo stays on the same offset all year, but London changes its clocks, so the gap between the two cities shifts during the year.

- 28 March 2027 — London puts its clocks forward an hour. Tokyo is then 8 hours ahead of London.
These dates come from the same time zone database your browser uses, so the converter above applies each change automatically on the day it happens.
Frequently Asked Questions: London & Tokyo
Can I compare London and Tokyo time directly?
Yes - this page loads London and Tokyo by default so you can see the current gap between them immediately. You can still change either city using the boxes above if you want a different comparison.
What do the common time zone abbreviations GMT, EST, and PST stand for?
These abbreviations identify a region's standard offset from UTC. GMT (Greenwich Mean Time) is the reference time for the UK, EST (Eastern Standard Time) covers the US East Coast such as New York and Washington, and PST (Pacific Standard Time) covers the US West Coast such as Los Angeles.
Does this time zone calculator automatically account for Daylight Saving Time (DST)?
Yes. TimeMatch.me reads the time zone database built into your own browser, which already knows whether any given city is currently observing daylight saving or standard time, and adjusts the calculation automatically all year round.
Does the site save my location or time data on a server?
No. TimeMatch.me runs entirely on the client side - every calculation happens on your phone or computer. Nothing about your location, your searches, or the cities you compare is sent to or stored on our servers.
Can I compare two specific time zones directly?
Yes. Besides the main comparator, dedicated pages such as the GMT to EST converter pre-load two common zones for a quick check, and you can always type any two cities into the boxes on any page.
