How Boise time is set
- One change rule for both halves of Idaho
- 2
- Federal law changes every zone's clocks on the same two Sundays, each when its own clock reaches the set hour. Boise's clock gets there first, so north Idaho changes an hour later, the same night. The law lets a split state exempt all of itself, or only its part in one zone. The tz database shows both parts of Idaho still changing their clocks.
- Boise's early years on Pacific Time
- PST
- The tz database records Boise on Pacific Time, Lewiston's clock today, until after the First World War. It cites no primary record for the switch to Mountain Time, so read it as the database's account.
Questions about Boise time
What time zone is Boise, Idaho, in?
Boise is in the Mountain Time zone, which federal regulation calls the fourth zone. Its winter time is MST, UTC-7 and its summer time MDT, UTC-6. The clock at the top of this page shows Boise time now, with seconds. Pocatello and Idaho Falls show the same.
Is Boise on the same time as Seattle?
No. Seattle keeps Pacific Time, so it is 1 hour behind Boise all year. Washington and Idaho change their clocks on the same Sundays, so summer does not alter the gap. Portland matches Seattle, though Ontario, on Oregon's border with Idaho, keeps Boise's time.
Is Boise on the same time as Denver?
Yes, every day of the year. Boise's and Denver's clocks go forward and back together, at the same instant. Utah, Colorado and Wyoming keep that clock too. Phoenix is on the same time as Boise in winter, then an hour behind it in summer.
Does all of Idaho keep Boise's time?
No. Boise's clock covers southern Idaho. Northern Idaho keeps Pacific Time and runs 1 hour behind Boise all year. Nine counties lie wholly on that side, including Kootenai, Latah, Nez Perce and Shoshone. Idaho County is split along the Salmon River. A call from Boise to Lewiston crosses a time zone without leaving the state.
