2025 time change dates for Idaho
At 2:00 AM the clocks jump straight to 3:00 AM in Idaho. That hour never happens, and everyone loses an hour of sleep.
At 2:00 AM the clocks return to 1:00 AM, so that hour is lived through twice and the night is an hour longer.
Idaho keeps MST/PST in winter and shifts one hour forward for the summer.

Economic Impact of DST in Idaho
The economic effects of Daylight Saving Time in Idaho are real but modest, and studies disagree on their size. Retailers and hospitality businesses generally favour DST, arguing that lighter evenings encourage shopping, dining out and other after-work spending — the US retail lobby was one of the main forces behind the 2005 extension of the DST period.
The transitions themselves carry a cost. Research from Chmura Economics has put the one-off economic cost of the spring change in the United States at roughly $430 million a year, driven by lost productivity, workplace injuries and the health effects of a disrupted night's sleep.
Health Considerations for Idaho Residents
The spring transition is the one that hurts. A study in Open Heart found the risk of heart attack rose by about 24% on the Monday after clocks went forward, before falling back to normal within the week. Research published in Current Biology found a 6% rise in fatal traffic accidents in the week following the spring change, with the effect strongest in the morning and in the western parts of time zones.
The autumn change, when most people gain an hour, shows no comparable spike. Researchers attribute the difference to sleep loss rather than to the clock change itself.
Background
- The Energy Policy Act of 2005 extended US DST by four weeks starting in 2007, moving the start to the second Sunday in March and the end to the first Sunday in November.
- 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.
- Arizona and Hawaii are the only US states that skip DST statewide, along with the territories of Puerto Rico, Guam, American Samoa and the US Virgin Islands.
Tips for Idaho
Take advantage of the 'extra' hour in fall to catch up on sleep or tackle a project.
Use the phrase 'Spring forward, fall back' to remember which direction to change your clocks.
Update your car clock, microwave, and other manual clocks that don't auto-update.
Consider the time change when scheduling meetings with people in other time zones.
Frequently asked questions
When do the clocks change in Idaho in 2025?
Clocks go forward on Sunday, March 9, 2025 and back on Sunday, November 2, 2025.
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.
