Tokyo

Tokyo is 9 hours ahead of London right now.
Does the gap change?
The gap isn't fixed. London changes its clocks for daylight saving time and Tokyo doesn't, so the difference moves during the year:
- From around March 29, 2027: Tokyo ahead by 8 hours
- From around November 1, 2027: Tokyo ahead by 9 hours
Best time to meet
Normal office hours in Tokyo and London don't overlap. The most workable window is 7 AM to 1 PM in London, which is 4 PM to 10 PM in Tokyo, with one side starting early or finishing late.
For a recurring meeting, it's fairest to rotate which city takes the inconvenient slot.
