Common questions

How many hours ahead is London of Tokyo?

London is 9 hours behind Tokyo right now. The gap is not fixed: it moves whenever either side changes its clocks.

What is the best time to call between Tokyo and London?

There is no hour inside working hours in both cities. 17:00–18:00 your time (08:00 there) is the cheapest compromise, and one side is taking a shoulder hour.

Do Tokyo and London change clocks on the same date?

Only one of them does, so the gap between them changes twice a year even though neither city moved relative to the sun.
