Yukon does not observe Daylight Saving Time
Yukon stopped changing its clocks in 2020 and now stays on UTC−7 year-round, marketed locally as Yukon Standard Time.
Yukon stays on MST for the whole year.

Technology and Time Changes in 2028
Phones, computers and anything else that syncs with an internet time server handle the transition on their own. What still catches people out in Yukon is the long tail of devices that don't: car dashboards, ovens and microwaves, wall clocks, older thermostats, and cheap alarm clocks with a DST setting hard-coded to a schedule that has since changed.
For anyone running servers, the transitions are a recurring source of bugs — duplicated or missing local timestamps around the changeover, cron jobs that fire twice or not at all, and stale operating system timezone databases. Storing timestamps in UTC and keeping the tzdata package current avoids almost all of it.
Did you know?
- Benjamin Franklin is often credited with inventing DST, but his 1784 essay was satire — he joked that Parisians could save candles by waking earlier. The modern proposal came from New Zealander George Hudson in 1895 and Briton William Willett in 1907.
- The Uniform Time Act of 1966 ended a chaotic period in which US cities set their own clock-change dates, and established a uniform national schedule.
- The European Parliament voted in 2019 to end mandatory clock changes, but member states never agreed on which time to keep, so the change has stalled indefinitely.
Frequently asked questions
When do the clocks change in Yukon in 2028?
They do not. Yukon does not observe Daylight Saving Time.
Which way do the clocks go?
"Spring forward, fall back" is the usual mnemonic: forward one hour in spring, back one hour in autumn.
Do I have to change anything myself?
Phones, computers and anything that syncs over the internet update on their own. Car clocks, ovens, microwaves and older wall clocks generally do not.
Is Daylight Saving Time being scrapped?
It has been proposed in many places and adopted in few. The European Parliament voted in 2019 to end mandatory clock changes and the change has stalled; in the United States the Sunshine Protection Act has repeatedly passed the Senate without becoming law. Most of the world that changes its clocks is still changing them.
