Daylight saving time, when the clocks change.

Daylight saving time 2026 starts in the United States on Sunday 8 March, when the clocks go forward at 2 am, and ends on Sunday 1 November, when they go back at 2 am. In the UK and the EU the clocks go forward on Sunday 29 March and back on Sunday 25 October. Pick your zone above and the page shows the next change for it, found in your browser's own time zone data, with the hour that is skipped or repeated and the time left.

How to use the page

1. Under Where, keep your own time zone or choose another, such as America/Chicago or Australia/Sydney.
2. Read Next clock change: the date, the direction, the clock time before and after, and how long is left.
3. Read Clock times skipped or Clock times repeated to see which clock times are affected.
4. Scroll to the five year table for every change in the zone, and to Well known places to compare. Press Copy result or Copy link to share it.

Spring forward, fall back

When the clocks go forward, an hour of the clock does not exist. In New York on 8 March 2026 the clock jumps from 2:00 AM to 3:00 AM, so 2:00 to 2:59 never happens, and that day is 23 hours long. When the clocks go back, an hour happens twice. On 1 November 2026 in New York the clock goes from 2:00 AM back to 1:00 AM, so 1:00 to 1:59 happens twice, and that day is 25 hours long. The saying is spring forward, fall back. South of the equator the seasons run the other way, so in the browser's data Sydney goes forward in October and back in April.

A change is not always one hour. In the browser's data, Lord Howe Island (the zone Australia/Lord_Howe) changes by 30 minutes, and the page shows the length of each change.

The US rule

The NIST page on daylight saving time (checked 18 Oct 2026, NIST daylight saving time) says that in the United States DST begins at 2:00 am on the second Sunday of March, when 2 am skips ahead to 3 am, and ends at 2:00 am on the first Sunday of November, when 2 am becomes 1 am and that hour is repeated. It says the rules changed in 2007 through the Energy Policy Act of 2005, which lengthened DST by about one month, and that DST and time zones are regulated by the US Department of Transportation, not by NIST.

The EU and UK rule

Directive 2000/84/EC of the European Union (checked 18 Oct 2026, EUR-Lex text of the directive) sets the summer-time period to begin at 1:00 a.m. Greenwich Mean Time on the last Sunday in March and to end at 1:00 a.m. Greenwich Mean Time on the last Sunday in October, in every Member State. The UK government says the same days for the UK: clocks go forward 1 hour at 1am on the last Sunday in March and back at 2am on the last Sunday in October (checked 18 Oct 2026, GOV.UK clock change dates). The directive's time is in GMT, so the local clock time differs by country.

The rule dates, 2026 to 2030

The US dates are the second Sunday of March and the first Sunday of November. The EU and UK dates are the last Sunday of March and of October. The US and Europe are out of step for a few weeks each spring and autumn, which matters for a call or a flight between them.

Places that do not change

The NIST page says DST is not observed in Hawaii, American Samoa, Guam, Puerto Rico, the Virgin Islands and the state of Arizona, with the exception of the Navajo Nation, which does observe it (the NIST page calls it the Navajo Indian Reservation). In the Well known places table, Phoenix and Honolulu show no change, and so do India and Japan in your browser's data. Outside these, the table shows the zones that do change, and any zone you pick above is checked the same way.

Why the dates come from your browser

The page does not keep its own list of dates. It asks your browser for the clock offset of the zone, day by day, and finds the day it changes, down to the second. That means the answer follows the time zone data your browser holds today. Rules can change, and browsers update their data on their own schedule, so a place that has just changed its rule may show an older answer. For a flight, a contract or a law, check the government's own page for the place.

Common problems

• My phone changed on a different day. Phones and computers get their own time zone updates. Check the zone name and update the device.
• No change found. The zone does not change in your browser's data, or the browser does not know it. Choose a nearby city.
• A meeting looks an hour off. Two places may change on different days. Compare them in the time zone converter.

To count down to a change, use the countdown to date. To see the time now in a place, use the online clock.
