City to city

London to Tokyo time — Tokyo is 9 hours ahead

Tokyo is 9 hours ahead of London during standard time. Once daylight saving begins the gap becomes 8 hours ahead, because the two cities do not change their clocks in step. Their normal working days overlap by roughly 0 hours.

Standard time

9 hours ahead

Applies while neither zone is on daylight saving — broadly November to March in the northern hemisphere.

Daylight saving

8 hours ahead

Applies while the clocks are forward. This pair does not keep a constant gap, so check the date.

How the two zones line up

London runs on Europe/London (UTC+0 in winter) and Tokyo on Asia/Tokyo (UTC+9). The difference between those offsets is what you add or subtract when converting a meeting time.

Daylight saving

Standard working days do not overlap at all. One side will need to take the call early or late, so alternate who makes the sacrifice.
