London and Tokyo Time Zone Comparison
This page is built for anyone planning a call or meeting between London and Tokyo. London sits in Europe and observes daylight saving time, while Tokyo is in Asia and stays on a fixed offset all year.
Because London and/or Tokyo observe daylight saving time for part of the year, the gap between them isn't fixed — it ranges between 8 and 9 hours depending on the season.
With a gap this large, business hours barely overlap between London and Tokyo — an early morning or a late evening on one side is usually needed to connect with the other.
