# Daylight Saving Time 2027: When Do the Clocks Change?

> In 2027 the clocks change on March 14 in the US and Canada, March 28 in Europe and the UK, and October 3 in Australia. The rules behind each date, the places that never change, and what to do about recurring meetings.

The three dates that decide 2027, and the one rule that explains all of them: northern-hemisphere clocks go forward in March, southern-hemisphere clocks go forward in October, and the gaps are not accidents — they are the first and last Sunday of the month.

## Quick answer

**Short answer:** in 2027 the clocks go **forward on Sunday, March 14** in the United States and most of Canada, and on **Sunday, March 28** in the European Union and the United Kingdom. They go **back on Sunday, November 7** in North America and **Sunday, October 31** in Europe. In Australia it is the other way round: forward on **October 3**, back on **April 4**. Add the two change dates to your calendar with our [2027 US & UK calendar file](https://toolpantry.app/downloads/clock-changes-us-uk-2027.ics), and check a recurring meeting with the [time zone meeting planner](https://toolpantry.app/timezone-meeting-planner).

## The 2027 dates

| Region | Clocks go forward | Clocks go back |
|---|---|---|
| United States, most of Canada | Sunday, March 14, 2027 | Sunday, November 7, 2027 |
| European Union, United Kingdom | Sunday, March 28, 2027 | Sunday, October 31, 2027 |
| Australia (most states) | Sunday, October 3, 2027 | Sunday, April 4, 2027 |
| New Zealand | Sunday, September 26, 2027 | Sunday, April 4, 2027 |

One thing to hold on to: **the southern hemisphere runs the opposite way**. Sydney and Auckland move forward while New York and London are still on standard time, then Europe and North America move forward three weeks later. If you schedule across both hemispheres, there is a window in late March where the two are out of step in the other direction than usual.

## The rules, which are simpler than the table

- **United States and Canada:** the second Sunday in March, and the first Sunday in November. "Second" and "first" are why the date moves — a calendar rule, not a fixed date.
- **European Union and United Kingdom:** the last Sunday in March, and the last Sunday in October. In 2027 those fall on the 28th and the 31st.
- **Australia:** the first Sunday in October, and the first Sunday in April.
- **New Zealand:** the last Sunday in September, and the first Sunday in April.

That is the whole mechanism. Every year the same four rules produce a different set of dates, which is why a calendar entry made in 2026 is wrong in 2027.

## What does not change at all

Plenty of places never touch their clocks, and if you are scheduling with them you can stop thinking about this:

- **Most of Arizona** (the Navajo Nation and most of the state observe DST; the rest does not) and **Hawaii** in the United States
- **Puerto Rico**, and most of the Caribbean
- **Japan, China, India, Singapore, Thailand** and most of Southeast and South-East Asia
- **Brazil** (no longer observes it) and **most of Africa**
- **Mexico**, apart from the border strip and a few northern states

The exception to the exception: a handful of countries — including Egypt, Israel, Iran, Lebanon and Chile — have rules that differ from their region, and some of them change them from year to year. For those, check the specific city.

## What to do about a meeting that repeats

This is the practical part, and it is where most of the damage happens. A weekly meeting pinned to a local time does not stay at the same local time across a clock change: it stays at the same *absolute* time, and its local rendering moves by an hour.

1. **Decide which time is fixed.** If the meeting is at 9am for the team, pin it to the zone of the people who attend most often, and accept that the far end sees it shift by an hour twice a year.
2. **If the absolute time matters, use UTC.** A recurring event in UTC keeps its instant; only the local rendering changes. This is what schedulers and CI systems do.
3. **Write the zone in the title.** "Standup 09:00 Europe/London" survives a calendar migration in a way that "Standup 09:00" does not.
4. **Check the meeting around the change itself.** The 2am window on the change date is the part that breaks: a call at 01:30 or 02:30 on the night of the transition may or may not exist, depending on the zone.

To see what a given UTC time lands on for a city on a given date, use the [time zone meeting planner](https://toolpantry.app/timezone-meeting-planner). It converts a time across two cities on any date, so you can check the week of the change without doing the arithmetic in your head.

## Add it to your calendar

Two date entries are enough for the US and the UK, and they are all-day events so no calendar app tries to apply a time-zone conversion to them:

- [Download the 2027 US & UK clock changes](https://toolpantry.app/downloads/clock-changes-us-uk-2027.ics) — one file, two events, no account needed
- Or add them by hand: **March 28, 2027** for the EU and UK, **March 14, 2027** for the US and Canada, **October 31, 2027** for the EU and UK, **November 7, 2027** for the US and Canada

We keep the 2026 dates and the meeting-time walkthrough on the [2026 clock change guide](https://toolpantry.app/blog/daylight-saving-time-ends-2026), and the [2026 guide](https://toolpantry.app/blog/daylight-saving-time-ends-2026) has the clock change helper showing the change and your local time for a set of cities.

## Notes

By the Tool Pantry team, October 2026. The 2027 dates were checked against published daylight-saving tables for the US, Canada, the EU, the UK, Australia and New Zealand on October 21, 2026. Countries change their rules occasionally, so re-check before you travel.

## FAQ

**When do the clocks change in 2027?**

On Sunday, March 14, 2027 in the United States and most of Canada, and on Sunday, March 28, 2027 in the European Union and the United Kingdom. The autumn dates are Sunday, November 7, 2027 for the US and Canada, and Sunday, October 31, 2027 for the EU and UK. In the southern hemisphere it is the other way round: Australia starts on October 3, 2027 and ends on April 4, 2027.

**Which places do not observe daylight saving time?**

Most of Arizona and Hawaii in the US, Puerto Rico, Japan, China, India, Singapore, Brazil, and most of Africa never change their clocks at all. A country can also change its rules, so check the specific city rather than the country when it matters.

**How do I stop a recurring meeting from shifting?**

Put the event in the calendar in UTC, or in the zone of the participants who are least likely to travel, and state the time zone in the title. A recurring meeting pinned to local time moves when the clocks do; the same meeting pinned to UTC keeps its absolute time and changes its local rendering instead.
