Markets & hours

Daylight saving time and market hours

Who changes their clocks and when in 2026–2027, what the mismatch weeks do to the London–New York overlap, and what to check in your platform.

Key takeaways

  • US clocks changed on 1 November 2026 and change again on 14 March 2027; the UK and EU follow on 28 March 2027.
  • Mexico City, Bogotá, Lima and Buenos Aires never change their clocks; their session and release times move with New York and London.
  • In the mismatch weeks the US is on summer time and the UK is not: the London–New York overlap lasts about five hours.
  • Your platform shows server time and a calendar shows its own time zone; after a clock change, check both.

Why a clock change elsewhere moves your trading day

Daylight saving time (DST) means putting clocks forward one hour for part of the year, usually the local summer. Forex has no single clock: each trading session follows its financial centre's local time, and US data releases follow Washington's, so when New York or London moves its clock, everything timed from that city moves by an hour everywhere else.

The forex market hours guide has the session tables; this page covers the change dates and the weeks in between.

Who changes their clocks, and the rule they follow

Each country sets its own rule; these are the ones that matter here, as of 6 November 2026:

  • United States (New York): second Sunday of March to first Sunday of November, at 02:00 local time.
  • United Kingdom and the EU (London, Frankfurt): last Sunday of March to last Sunday of October, at 01:00 UTC.
  • Australia (Sydney, New South Wales): first Sunday of October to first Sunday of April, the southern summer.
  • Japan (Tokyo): no daylight saving time.
  • Mexico: no seasonal time since the Ley de los Husos Horarios took effect on 30 October 2022, except in listed northern-border municipalities; Mexico City and central Mexico stay on UTC−6.
  • Colombia, Peru and Argentina: no daylight saving time; Bogotá and Lima stay on UTC−5, Buenos Aires on UTC−3.
  • Chile (Santiago and continental Chile): first Saturday of September to first Saturday of April, at 24:00, by decree of the Ministerio del Interior, currently to April 2029; Aysén and Magallanes stay on UTC−3, Easter Island has its own time.

The 2026–2027 calendar of changes

London went back on 25 October 2026 and New York on 1 November 2026; the next round is in March and April 2027. Checked on 6 November 2026 against the sources below.

Chile changes at midnight, so the Sunday shown is its first day on the new time; from 4 April 2027 Santiago (UTC−4) and Buenos Aires (UTC−3) no longer share a time.

The mismatch weeks: when the US and the UK are out of step

The US changes its clocks before the UK in March and after it in early November, so for a few weeks New York is on summer time and London is not: in 2026, 8 March to 29 March and 25 October to 1 November; in 2027, 14 March to 28 March and 31 October to 7 November.

In those weeks New York (08:00–17:00 local time) opens at 12:00 UTC, its summer position, while London (08:00–17:00 local) still closes at 17:00 UTC, its winter position: about five hours of overlap, not four. Liquidity in EUR/USD and GBP/USD often follows the overlap, but a longer overlap says nothing about volatility, how far prices move.

London–New York overlap in local time (approximate)
City (time zone)Both on summer time (around July)Both on standard time (around January)Mismatch weeks (US on summer time, UK not)
Mexico City (UTC−6)06:00–10:0007:00–11:0006:00–11:00
Bogotá and Lima (UTC−5)07:00–11:0008:00–12:0007:00–12:00
Santiago (UTC−4 / UTC−3)08:00–12:0010:00–14:0009:00–14:00
Buenos Aires (UTC−3)09:00–13:0010:00–14:0009:00–14:00

Santiago is on UTC−3 in both mismatch windows, so its mismatch column is not July plus an hour.

What moves on your screen

Platform time

MetaTrader 5 shows the broker's server time, not your device's, in Market Watch and on the chart's time axis; that time zone may follow its own daylight saving rule, so the clock can jump on a date that is not your country's. On any platform, check which time zone the chart clock uses before reading a release time. This guide does not state it.

Release times

Releases keep their publisher's local time: US statistics come out at 08:30 Eastern Time whether or not Europe has changed its clocks, and an economic calendar converts them to the time zone in its settings. The table shows 08:30 Eastern, the US jobs report and CPI time; the New York open is 30 minutes earlier.

08:30 US Eastern Time in local time (approximate)
City (time zone)Around JulyAround JanuaryMismatch weeks
Mexico City (UTC−6)06:3007:3006:30
Bogotá and Lima (UTC−5)07:3008:3007:30
Santiago (UTC−4 / UTC−3)08:3010:3009:30
Buenos Aires (UTC−3)09:3010:3009:30

Where clocks never change, the mismatch column equals July's: a US release depends only on the US clock. Around a release, spreads can widen and prices can gap whatever the clocks say; a stop loss inside a gap is filled at the next available price.

A checklist for the week the clocks change

None of this says whether to trade; it is a list of checks so a time on your screen means what you think.

  1. Compare the platform clock with UTC or your phone; repeat on the Monday after each date above.
  2. Read the hours in the Symbol Specifications of each instrument you trade; they are in server time and some instruments have a daily break.
  3. Check your economic calendar's time zone setting, then compare one release time with the publisher's schedule.

Hypothetical example: the New York open on a hypothetical Monday, 15 March 2027

New York
UTC−4, summer time
London
UTC+0, standard time
Your city
Bogotá, UTC−5
  1. New York open: 08:00 + 4 h = 12:00 UTC
  2. London close: 17:00 UTC
  3. Overlap: 12:00 to 17:00 UTC, five hours
  4. Bogotá: 12:00 − 5 h = 07:00, 17:00 − 5 h = 12:00

Result: on 15 March 2027 the overlap in Bogotá is 07:00 to 12:00; from 29 March, 07:00 to 11:00 again

Risk note

Contracts for Differences (CFDs) are complex instruments and come with a high risk of losing money rapidly due to leverage.

The clock-change dates and converted times in this guide were checked on 6 November 2026 and can change; they are general information only, not NextTrade's trading schedule, and no duty to update them is assumed. Spreads can widen and prices can gap at any hour, and orders may be filled at a worse price than you set. See the Risk Disclosure Policy for the full risks.

Frequently asked questions

When does the time change in the United States in 2027?

US clocks go forward at 02:00 local time on Sunday 14 March 2027 and back on Sunday 7 November 2027. In Mexico City (UTC−6), which never changes, the New York open moves from 07:00 to 06:00 in March and back to 07:00 in November.

Does the time change in Mexico?

Not in most of the country. The Ley de los Husos Horarios, in force since 30 October 2022, ended seasonal time; Mexico City and central Mexico stay on UTC−6. Only listed northern-border municipalities, such as Ciudad Juárez, Tijuana and Matamoros, keep the US dates.

Why does the London–New York overlap last five hours in some weeks?

New York moves to summer time before London in March and back after it in early November, so it opens at 12:00 UTC while London still closes at 17:00 UTC: five shared hours, not four. In 2027: 14 March to 28 March and 31 October to 7 November.

Does the platform's time change with daylight saving?

MT5 shows the broker's server time in Market Watch and on the chart's time axis, and that time zone may follow its own daylight saving rule. This guide does not state it: on any platform, check the chart clock's time zone against UTC after each change date.
