Daylight saving time 2027: when do the clocks change?
Every 2027 clock change by region, with the exact local time it happens — and the 2026 dates next to them so you can see the pattern.
Short answer
In 2027 the United States and Canada spring forward on Sunday 14 March and fall back on Sunday 7 November. The United Kingdom and the European Union change on Sunday 28 March and Sunday 31 October. Australia's daylight-saving states end summer time on Sunday 4 April and start it again on Sunday 3 October. India, China, Japan, the Gulf, Brazil and Mexico do not change clocks at all.

Why the dates differ by region
There is no world standard for daylight saving: each country picks its own rule, and most express it as a weekday-of-month ("last Sunday of March") rather than a fixed date. That is why the US and Europe are out of step for two to three weeks every spring and autumn — the US moves first in March and last in November — and why the difference between New York and London is 5 hours most of the year but 4 hours during those weeks.
The southern hemisphere runs the opposite way: Sydney, Melbourne, Auckland and Santiago are on summer time from October to April, so their gap with Europe swings by up to two hours across the year. And a growing list of countries has simply stopped changing: Mexico (2022), Brazil (2019), Turkey (2016), Russia (2014) and Paraguay (2024, now permanently on summer time).
Timezone Matcher does not store any of these dates. Every table on this page — and every city-pair page on the site — is computed from the IANA time-zone database at the moment you load it, the same source Linux, macOS, Android and most servers use. If a government changes its rule, the page updates when the runtime's data does.
Frequently asked questions
When does daylight saving time start in 2027 in the US?
On Sunday 14 March 2027 at 2:00 a.m. local time, when clocks jump to 3:00 a.m. It ends on Sunday 7 November 2027 at 2:00 a.m., when clocks go back to 1:00 a.m. The rule since 2007 is the second Sunday of March to the first Sunday of November.
When do the clocks change in Europe in 2027?
The EU and the UK move forward on Sunday 28 March 2027 (01:00 UTC: 02:00 → 03:00 in Central Europe, 01:00 → 02:00 in the UK, Ireland and Portugal) and back on Sunday 31 October 2027 (01:00 UTC). The rule is the last Sunday of March and the last Sunday of October.
Is the EU abolishing the clock change?
The European Parliament voted in 2019 to end seasonal changes, but the member states never agreed on which time to keep, so the directive has been stalled in the Council since then. As of this page's publication, the 2027 changes are still scheduled.
Will the US stop changing clocks?
The Sunshine Protection Act, which would make daylight saving time permanent, passed the Senate in 2022 but has not become law. Unless Congress acts, the 2027 changes on 14 March and 7 November stand.
Which countries do not use daylight saving time?
Most of the world: all of Asia except Israel and parts of the Levant, all of Africa except Egypt and Morocco's Ramadan exception, and nearly all of Latin America (Chile, Cuba and Paraguay's permanent summer time are the exceptions). In total roughly 70 countries change their clocks; about 120 do not.
Why is the time difference between two cities not the same all year?
Because the two cities change their clocks on different dates, or only one of them changes at all. New York–London is 5 hours for most of the year but 4 for a few weeks in March and November; London–Dubai is 4 hours in winter and 3 in summer. The city-pair pages on this site show the full calendar for each pair.
