You’re driving north on Highway 95, watching the pine trees blur and feeling the air get just a little bit crisper. You cross the Salmon River, wind through the canyons, and suddenly, your phone screen flickers. The clock jumps back an hour. You’ve just hit the "Time Curtain." If you’re heading to Coeur d'Alene, you aren’t just entering a world of alpine lakes and world-class golf; you’re entering a different time zone than the rest of the state.
It’s confusing. Honestly, it trips up locals too.
Most people think Idaho is a Mountain Time state. They aren't entirely wrong, but they aren't right either. When you talk about Coeur d'Alene time, you are talking about Pacific Standard Time (PST). While Boise and the southern jagged bits of the state are waking up and drinking coffee, folks in Coeur d'Alene are still tucked in for another hour. It’s a geographical quirk that defines the culture, the economy, and the very rhythm of North Idaho.
The invisible line: Where Coeur d'Alene time actually begins
The split isn't random. It’s dictated by the landscape. The official boundary between the Mountain and Pacific time zones in Idaho follows the Salmon River. Everything north of that river—the Panhandle—is on Pacific Time. This includes Coeur d’Alene, Sandpoint, Moscow, and Bonners Ferry.
Why?
Geography. Back when the railroads were the lifeblood of the West, the Panhandle was economically tethered to Spokane, Washington. It made zero sense for a businessman in Coeur d'Alene to be an hour ahead of his partners thirty minutes away in Spokane. The mountains created a natural barrier between the north and south of the state, making the trek to Boise a multi-day ordeal before modern highways. Basically, North Idaho looked west for its news, its supplies, and its clock.

Even today, if you live in Coeur d'Alene, you’re essentially part of the "Inland Northwest" hub centered around Spokane. You shop there. You fly out of their airport (GEG). You live on their time.
The daylight saving struggle
It gets weirder. Idaho observes Daylight Saving Time, so when the clocks "spring forward" or "fall back," the entire state moves together, but that one-hour gap remains. In the height of summer, the sun stays up late. I mean really late. Because Coeur d'Alene is so far north and sits on the eastern edge of the Pacific Time Zone, you’ll see twilight lingering past 9:30 PM in June. It’s glorious for a late-night boat session on the lake, but it can wreak havoc on your internal clock if you’re trying to get kids to sleep.
Planning your trip around the clock
If you’re coming from the south, don't trust your car's GPS clock immediately. It can lag. I’ve seen people show up an hour early for dinner reservations at Beverly’s because they didn’t realize their phone hadn't updated yet.
If you are booking a flight, remember that the Spokane International Airport is on Pacific Time—the exact same as Coeur d'Alene time. You don't need to do any mental math when crossing the Washington-Idaho border. Just stay on Pacific Time. However, if you are driving up from Boise or Salt Lake City, you "gain" an hour. It’s the closest thing to time travel you’ll get without a DeLorean.
Why the "Time Curtain" matters for business
For professionals working remotely or businesses with offices across the state, the time difference is a constant logistical hurdle.

Imagine a 9:00 AM meeting in Boise. For a consultant in Coeur d'Alene, that’s an 8:00 AM start. It sounds simple until you’re juggling calendar invites that don't always auto-detect the zone correctly. The University of Idaho has it toughest; their main campus is in Moscow (Pacific Time), but they have a massive presence and legal school in Boise (Mountain Time). They basically run a dual-clock existence.
The Lake Coeur d'Alene lifestyle: Does anyone actually care what time it is?
There is a saying up here: "Lake Time."
It’s a real thing. When the weather hits that perfect 80-degree sweet spot in July, the strict adherence to the clock tends to melt away. The city revolves around the water. Whether you’re docking at the Boardwalk Marina or hiking Tubbs Hill, the "Pacific" influence isn't just about the clock; it’s about the attitude. It’s slower. Less frantic than the tech-heavy buzz of Southern Idaho.
People move to Coeur d'Alene specifically for this shift. They want the extra hour of evening light. They want the connection to the Pacific Northwest vibe.
Common misconceptions about the North Idaho clock
- "The whole state is Mountain Time." Nope. Only about 75% of it.
- "The time change happens at the border." No, you can be deep inside Idaho and still be on Pacific Time. The change happens at the Salmon River bridge near Riggins.
- "It doesn't affect the weather." While the clock doesn't change the temperature, the latitude does. Being on Pacific Time means the sun rises later in the winter. In December, you might not see "real" daylight until nearly 8:00 AM.
Practical steps for navigating Coeur d'Alene time
Managing the transition doesn't have to be a headache if you follow a few basic rules of thumb.

First, hard-set your digital calendars. If you’re traveling between Boise and Coeur d'Alene, don't rely on "Automatic Time Zone" settings on your laptop for important meetings. Manually set the event to the location’s time zone to avoid the dreaded "hidden hour" mistake.
Second, check your flight connections. If you are flying from a Mountain Time hub (like Denver or Salt Lake) into Spokane, double-check your arrival time. You’ll arrive "earlier" than you think, which is great for catching a rental car but bad if you've told your ride to pick you up based on your departure time zone.
Third, embrace the evening. Since Coeur d'Alene is on the eastern edge of its zone, the late sunsets are a gift. Plan your outdoor activities for the "golden hour," which lasts significantly longer here than in many other parts of the country.
Finally, confirm appointments twice. If you are dealing with service providers, doctors, or tours that operate near the time zone boundary (like those near the Salmon River), always ask: "Is that Pacific or Mountain time?" It sounds redundant until you're the guy standing outside a locked door for sixty minutes.
The "Time Curtain" is a quirk that makes North Idaho unique. It’s a physical reminder that the Panhandle is its own world, disconnected from the desert south and tethered to the rugged, evergreen Pacific Northwest. Respect the river, watch your watch, and enjoy that extra hour.
