What the data shows

• Over the next 12 months the gap is 5 hours for 350 days, 4 hours for 15 days, because the two places change their clocks on different dates.

  How we calculated this: Days per distinct difference across the period.

• For three short spells (25 Oct–1 Nov 2026, 14–28 Mar 2027 and 31 Oct–7 Nov 2027) the difference is 4 hours instead of the usual 5 hours, because the two places change their clocks on different weekends. Re-check meeting and call times then.

  How we calculated this: Intervals shorter than six weeks whose difference is not the typical one (UTC dates of the clock changes that start and end them).

• At the usual difference, 09:00–17:00 working days overlap for 3 hours: 09:00–12:00 in New York, 14:00–17:00 in London.

  How we calculated this: Intersection of 09:00–17:00 local in both places at the typical difference.
