DST ends in the US and Canada on Sunday, November 7, 2021.


Clocks will be set back 1 hour from 02:00 (2 am) to 01:00 (1 am) in each time zone.

DST in the US starts again on Sunday, March 13, 2022.

As always, Europe will end DST a week before the US, on October 31, 2021.

Affects Most of the US

On November 7, the time will change in almost all of the United States.

Only the following areas do not change their clocks:

Canada: DST Change

In Canada, clocks will change in almost all areas, except:

Up to US Congress to Change DST Law

According to the National Conference of State Legislatures, 19 states have enacted legislation or passed regulations for permanent DST.

Congress must first pass a federal law that would allow states to observe DST year-round. The current law only allows states to forgo DST, but no states have received congressional approval to permanently stay on DST year-round.

Legislation in 2021:

Legislation in 2020:

  • In February, the Utah Senate voted to approve Senate Bill 59. The bill would have Utah spring ahead and stay ahead permanently, but it requires action by at least four western states before taking effect.
  • In February, the Governor of South Carolina signed Act No. 113 to put the state on year-round DST.
  • In March, Georgia adopted House Resolution 1240, urging the federal government to allow states to switch to permanent DST.
  • In March, the Idaho Governor signed Senate Bill 1267, making DST permanent in the state.
  • In March, the Wyoming Governor signed House Bill 0044, which aims to establish DST as the official time year-round. It needs to be approved by voters at the next general election.
  • In June, the Governor of Louisiana signed House Bill 132 to adopt Daylight Saving Time as the standard time.

Mexico: Northern Border Cities Follow the US

Some northern Mexican border towns, such as Tijuana and Juarez (Ciudad Juárez), end DST on November 7, with the US and Canada.

The rest of Mexico ends DST one week earlier on Sunday, October 31—on the same date as Europe's DST change.

The states of Sonora and Quintana Roo do not observe DST at all, so the clocks will not change there.

Other Countries and Territories

DST will also end on November 7 in Cuba, Bermuda, the Bahamas, Saint Pierre and Miquelon, and Thule Air Base in Greenland.

Set Clocks Back or Ahead?

One easy way to remember which way to set your clock is to keep in mind one of these sayings: “Spring forward, fall back” or “Spring ahead, fall behind.” The clocks spring ahead (= losing 1 hour) in the spring when DST starts, and they fall back one hour (= gaining 1 hour) when DST ends in the fall.
