On Sunday 1 November 2026, clocks in 47 of the 422 zone names this site lists go back one hour. It is the last change in UTC offset anywhere this year, and no zone name changes again until 14 March 2027. This guide lists every clock change of 2026, then looks at the five zone names that sprang forward in March and did not fall back. For the zone-by-zone detail of the American change, see the guide to the US change.
The table reads each zone name through 2026 with tzdata 2026f, the release of 27 October 2026 (release notes), and lists every change in UTC offset. 131 of the 422 zone names change at least once. The other 291 keep one offset all year. There are 22 rows on 18 dates: 131 zone-name changes forward and 128 back. A zone name is a database name, not a country, so the totals say how many names a computer has to update, not how many places have moved their clocks. Dates are in UTC, so a change at 21:00 UTC on 24 October is already early on 25 October in Israel and Lebanon.

Method: Each of this site's 422 zone names was read through 2026 with tzdata 2026f and every change in UTC offset was listed. Changes are grouped by UTC date and size. Zone names are database names, not countries or people: one place can have several.
The two biggest days are 29 March and 25 October, each with 58 zone names. All 58 change at exactly 01:00 UTC, so that clocks in London and Paris move together. In North America the same single day is spread over 7 hours of UTC, because each zone changes at 02:00 on its own clock. Besides the United States and Canada, the 47 names on 1 November include Mexico’s border zones (America/Tijuana, America/Matamoros, America/Ojinaga and America/Ciudad_Juarez), the Bahamas, Haiti, Turks and Caicos, Bermuda, Saint-Pierre and Miquelon, and Greenland’s Thule. Antarctica/Troll is the only zone name that moves by two hours, forward on 29 March and back on 25 October. Australia/Lord_Howe moves by 30 minutes, back on 4 April and forward on 3 October. Africa/Cairo has its own two dates, 23 April and 29 October. The worldwide list for 2026 gives the same dates by country.
January, May, June, July, August and December have no clock change anywhere. The most zone-name changes fall in March (117), October (72) and November (47). The months of the northern summer are empty because every daylight-saving zone has already changed and none has yet to change back.
| Month | Change dates | Zone names forward | Zone names back |
|---|---|---|---|
| January | 0 | 0 | 0 |
| February | 1 | 0 | 2 |
| March | 5 | 117 | 0 |
| April | 3 | 1 | 13 |
| May | 0 | 0 | 0 |
| June | 0 | 0 | 0 |
| July | 0 | 0 | 0 |
| August | 0 | 0 | 0 |
| September | 3 | 5 | 2 |
| October | 5 | 8 | 64 |
| November | 1 | 0 | 47 |
| December | 0 | 0 | 0 |
Method: Counted from the table above. A zone name that changes twice in a month is counted twice.
On 8 March 2026, 52 zone names moved their clocks forward. On 1 November 47 move back. The difference of 5 is Edmonton, Havana, Inuvik, Vancouver and Winnipeg. Each of these changed its clock on 8 March, and none of them goes back.
British Columbia’s government said that spring forward on 8 March would be the last time change, ending twice-yearly clock changes (Government of British Columbia). The release notes of the time zone database say the province moved to permanent UTC−7 on 9 March (tz database release notes). Alberta proclaimed its change on 18 June (Order in Council 204/2026), and the Northwest Territories followed on 21 August. Both are on permanent UTC−6, and the database covers most of the Northwest Territories with the Edmonton zone. Only Inuvik has its own name.
Manitoba announced on 17 September that it would stay on daylight time, and its government said clocks will not revert to standard time on 1 November (Government of Manitoba). The change took legal effect on 31 October. The database notes that Ontario issued a regulation setting the part of the province west of 90°W to UTC−5 all year, in force on 1 November, so that north-western Ontario stays level with Winnipeg (Ontario Regulation 333/26; tz database northamerica). Winnipeg therefore stays on the clock it has had since 8 March.
Cuba is the odd one out. On 24 October the authorities announced that summer time would stay in force until 7 November 2027, and release 2026f of the database, issued three days later, carries the change (CiberCuba). Havana stays on UTC−4. Unlike the Canadian provinces, Cuba has not given up changing clocks for good: the stay is dated, to 7 November 2027. The database notes say the measure delays the start of school and work by 30 minutes during the period when standard time would normally apply.
| Place | Clock from 1 Nov | Before 1 Nov | From 1 Nov |
|---|---|---|---|
| Winnipeg | UTC−5 | Same time as Chicago | 1 h ahead of Chicago |
| Vancouver | UTC−7 | Same time as Los Angeles | 1 h ahead of Los Angeles |
| Edmonton | UTC−6 | Same time as Denver | 1 h ahead of Denver |
| Inuvik | UTC−6 | Same time as Denver | 1 h ahead of Denver |
| Havana | UTC−4 | Same time as New York | 1 h ahead of New York |
Method: Offsets read at 12:00 UTC on 31 October and on 2 November 2026 from tzdata 2026f. Inuvik is compared with Denver because the territory shares Edmonton's clock.
Look at the rows with a gap of zero before 1 November and one hour from it. Until Sunday, each of these five clocks matched a big American neighbour. From Sunday each is an hour ahead of it, because the neighbour went back and they did not. A 09:00 call in Chicago is now 10:00 in Winnipeg. The same is true for Vancouver and Los Angeles, Edmonton and Denver, and Havana and New York.
The release notes call the 1 November entries for British Columbia, Alberta, the Northwest Territories and Manitoba a temporary hack. The laws took effect earlier, on 9 March, 18 June, 21 August and 31 October, but the database pretends each change happens on 1 November at 02:00 to work around a limitation in Unicode CLDR and ICU, and plans to remove the hack once those are fixed (release notes). The offset does not move on that row. Only the abbreviation does: the notes describe Vancouver’s row as a change from PDT to MST. This guide counts changes in UTC offset, so those rows are not counted. If they were, the four places would look as though they changed their clocks on 1 November when they did not.
The same files record Morocco’s change. The notes say the government adopted a decree on 25 June that abrogates the 2018 decree which put the country at +01 with daylight saving during Ramadan, and that the plan is to go back to +00 without daylight saving on 20 September at 02:00 (tz database africa). The table shows Africa/Casablanca going back on 15 February for Ramadan, forward on 22 March and back for good on 20 September. Africa/Casablanca and Africa/El_Aaiun are the zone names with the most changes in 2026, 3 each.
The next clock change anywhere is on 14 March 2027, when 47 zone names in North America spring forward, the first at 05:00 UTC. That is 133 days after 1 November. It is not the longest gap of the year: the 136 days from 23 April to 6 September were longer. To check a meeting across the new gaps, use the time zone converter. The clock widgets can put a countdown to the next change on another site.
A phone, server or app that has not updated its time zone data since before these releases will still show the old rules. The notes date the releases: 2026b on 22 April, 2026c on 8 July, 2026d on 11 September, 2026e on 29 September and 2026f on 27 October. This site reads 2026f. The sources below are the notes and files the numbers came from.
