Official 2026 markers (France, UK, USA) and Morocco’s special case (temporary adjustment during Ramadan).
| Zone | Forwarding by one hour | Falling back by one hour | Notes |
|---|---|---|---|
| France (mainland) | March 29, 2026 — 02:00 → 03:00 (UTC+1 → UTC+2) | October 25, 2026 — 03:00 → 02:00 (UTC+2 → UTC+1) | Legal base time: UTC+0 (same as the UK). Legal text (Legifrance) |
| European Union (*) | March 29, 2026 at 01:00 UTC | October 25, 2026 at 01:00 UTC | Common instant set at 01:00 UTC; applied simultaneously in local time across continental European time zones |
| Morocco | March 22, 2026 — 02:00 → 03:00 (UTC+0 → UTC+1) | February 15, 2026 — 03:00 → 02:00 (UTC+1 → UTC+0) | Morocco returns to standard time (UTC+0) during Ramadan (this year from February 15 to March 22, 2026), then goes back to UTC+1 after the end of the holy month. |
| United Kingdom (UK) | March 29, 2026 — 01:00 → 02:00 (UTC+0 → UTC+1) | October 25, 2026 — 02:00 → 01:00 (UTC+1 → UTC+0) | Base Legal time UTC+0, same as France |
| United States (DST – most states) | March 8, 2026 — 02:00 → 03:00 (example, ET: EST → EDT) | November 1, 2026 — 02:00 → 01:00 (example, ET: EDT → EST) | ET, CT, MT, PT, AKT, HAT, Exceptions: Hawaii, part of Arizona |
| Canada (DST – most states) | March 8, 2026 — 02:00 → 03:00 (example, ET: EST → EDT) | November 1, 2026 — 02:00 → 01:00 (example, ET: EDT → EST) | AT, ET, CT, MT, PT, NT, Exceptions: Saskatchewan, parts of Yukon and BC |
Within the European Union, the clock change takes place at the same instant (01:00 UTC), which maintains constant time offsets between Member States.
By contrast, time offsets with the outside vary over the course of the year: one can speak of variability in time offsets.
It goes without saying that, without clock changes, time offsets would naturally remain stable throughout the year.
In mainland France, clocks move forward on March 29, 2026 (02:00 → 03:00) and move back on October 25, 2026 (03:00 → 02:00), local time.
Because Europe and North America change clocks on different dates. In 2026, the offset changes temporarily from March 8 to March 29, and again from October 25 to November 1.
No. Many French overseas territories do not change clocks. When mainland France changes time in March and October, the offset with those territories can vary temporarily.
No. In the US, Hawaii and most of Arizona do not observe DST. In Canada, Saskatchewan and some local areas do not observe DST (rules vary by region).
Morocco generally runs on UTC+1 but often shifts time during Ramadan (commonly to UTC+0) and returns afterward. Exact dates may vary by one day depending on moon sighting.
You can cite the French legal text on Légifrance that defines legal time and its reference to UTC. The link is provided in the table notes.
Oui. Dans l’Union européenne, le changement d’heure intervient au même instant (01:00 UTC). Il est ensuite décliné en heure locale dans chaque fuseau. Cette simultanéité maintient des décalages constants entre États membres.
Oui. En l’absence de changement d’heure saisonnier, les décalages entre pays resteraient stables tout au long de l’année. Les variations observées aujourd’hui proviennent des dates différentes de changement d’heure selon les régions du monde.
