Clock changes 2026–2027: how meeting times shift
Countries don't change their clocks on the same day. For a week or more, the gap between two cities can be an hour smaller or bigger than usual — and recurring meetings quietly land at the wrong time for someone.
Upcoming dates
| 27 Sep 2026 | New Zealand | Clocks go forward 1 hour |
| 4 Oct 2026 | Australia (Sydney, Melbourne, Canberra, Hobart, Adelaide) | Clocks go forward 1 hour |
| 25 Oct 2026 | UK, EU and most of Europe | Clocks go back 1 hour |
| 1 Nov 2026 | United States and Canada | Clocks go back 1 hour |
| 8 Mar 2027 | United States and Canada | Clocks go forward 1 hour |
| 28 Mar 2027 | UK, EU and most of Europe | Clocks go forward 1 hour |
Many places — including most of Asia, Africa and South America — don't change clocks at all.
The tricky week: 25 Oct – 1 Nov 2026
Europe falls back a week before the US. During that week:
- New York is 4 hours behind London instead of the usual 5.
- Chicago is 5 hours behind London instead of 6, and Los Angeles 7 instead of 8.
- A 9:00 New York call that is normally 14:00 in London becomes 13:00 in London.
How to schedule safely
- Pick the actual meeting date in the planner — it uses that day's clocks, not today's.
- Send invites from a calendar (Google or Outlook), so each person sees their own local time.
- For recurring meetings, warn attendees in the other region that the time will move for a week.
