How the gap works

The gap is not constant. Because London changes its clocks for daylight saving time and Tokyo does not, the difference becomes 9 hours for part of the year. The live section above shows the exact gap right now and when it next changes.

  • London (United Kingdom) is in the Europe/London time zone: UTC+0 (GMT) or UTC+1 (BST).
  • Tokyo (Japan) is in the Asia/Tokyo time zone: UTC+9 (JST).

Best time to call or meet

London and Tokyo have no overlap in standard 9-to-5 working hours, so one side needs to start early or finish late. If you stretch the day to 7 AM to 10 PM in both cities, the shared window is 7:00 AM to 2:00 PM in London (3:00 PM to 10:00 PM in Tokyo).

The best time to call is around 10:30 AM in London (6:30 PM in Tokyo). That time falls outside standard 9-to-5 hours in at least one city. These times use the usual gap; for a few weeks each year, shift them by the difference noted above.
