About MST
A fixed, year-round offset.
Yukon Time (MST) keeps a steady UTC−07:00 year-round in Canada's Yukon—no daylight saving shifts mean clocks stay the same all year, making life and collaboration simpler across the territory.
IANA zones · the technical identifiers
The 2 zones that resolve to MST.
For software, always store the IANA identifier — never the abbreviation alone. The database keeps these zones distinct because their rules can, and historically did, diverge.

These named zones share MST's offset today. When daylight saving rules differ, they drift apart for part of the year.

Frequently asked questions
Common questions about MST, daylight saving, and how to handle it in software. Can't find what you need? Email [email protected].
- Why doesn’t Yukon Time observe daylight saving?
- Yukon permanently stopped DST in 2020, so MST runs at UTC−07:00 all year, giving a consistent rhythm for schedules and planning.
- Which areas use Yukon Time (MST)?
- It covers key Yukon communities in Canada such as Dawson and Whitehorse, all unified under a single UTC−07:00 standard.
- When did Yukon stop using DST?
- The region ended DST on 2020-11-01, moving permanently to standard time—its current offset has been stable ever since.
- How does no DST affect daily life?
- Business hours, school times, and broadcasts stay predictable year round—no spring-forward / fall-back confusion with neighbors or partners in other zones.
- What’s unique about Yukon Time compared to other North American MST regions?
- Many Mountain Time areas switch to Mountain Daylight Time in summer, but Yukon stays on UTC−07:00 all year, like most of Arizona and, from November 2026, British Columbia.
- Is Yukon Time the same as Mountain Standard Time elsewhere?
- While the offset (UTC−07:00) matches, Yukon skips the spring/summer shift to daylight time that many other MDT regions use.
- Does Yukon Time align with any US time zones?
- It always matches Arizona (except the Navajo Nation). It matches the rest of US Mountain Time in winter, and US Pacific Time in summer.
- What’s the time difference with Pacific Time during summer?
- In summer, US Pacific Time (PDT, UTC−07:00) matches Yukon. In winter, the US West Coast is one hour behind. British Columbia stays on UTC−07:00 all year from November 2026, so it matches Yukon year-round.
