It’s incredibly annoying. You glance down at your wrist, expecting to see exactly how much time you have left before your next meeting, only to realize your tracker thinks it's three hours ago. Or worse, yesterday.
If you're wondering how to adjust time on a Fitbit, you aren't alone. Honestly, it’s one of the most common complaints in the Fitbit community forums, right up there with "why won't my sleep stages show up?" and "my screen just went black." You’d think a device designed to track milliseconds of heart rate data would be able to tell the time correctly, but because these wearables rely so heavily on your phone’s GPS and internal clock, things get messy. Usually, it's a sync issue. Sometimes it's a time zone glitch. Occasionally, it's just the app being stubborn.
The Quickest Way to Adjust Time on a Fitbit
Most people think there’s a "Set Time" button buried in the settings on the watch itself. There isn't.
Fitbit devices—whether you're rocking a Charge 6, an Inspire 3, or the high-end Sense 2—don't actually have an internal manual clock you can toggle. They are basically "dumb" clocks that inherit their intelligence from your smartphone. If the time is wrong, your first move should always be a forced sync. Open the Fitbit app on your iPhone or Android. Pull down on the main dashboard screen. You’ll see that little rotating circle at the top. Once it finishes, the time usually snaps back to reality.
But what if it doesn't? That’s when you have to dive into the "Automatic Time Zone" settings within the app.
Navigate to your profile icon (or the device icon in the top left), go to App Settings, and look for Time Zone. If "Set Automatically" is turned on and the time is still wrong, toggle it off. Manually select your time zone. Sync again. It feels counterintuitive to turn off an automatic feature to make things work, but in the world of wearable tech, manual overrides are often the only way to clear a data bottleneck.
When Daylight Saving Time Ruins Everything
Every March and November, Fitbit users across the globe wake up to a tracker that is exactly one hour off. It’s a classic.

The device doesn't just "know" the sun stayed up longer. It has to receive that specific packet of data from your phone. If you slept with your phone in Airplane Mode or if your Bluetooth decided to take a nap, your Fitbit will be stuck in the past. To fix this, you have to ensure your phone’s system time is correct first. If your phone says 8:00 AM but your Fitbit says 7:00 AM, the handshake between the two has failed.
Restarting your phone is the "have you tried turning it off and on again" cliché that actually works here. Once the phone has the right time from the cellular tower, the Fitbit app can push that update to your wrist.
Traveling Across Borders
Crossing time zones is the ultimate test for a fitness tracker.
Let's say you fly from New York to Los Angeles. You land, take your phone out of Airplane Mode, and it updates to Pacific Time. Your Fitbit might still be clinging to Eastern Time like a stubborn tourist. This usually happens because the app isn't running in the background. Fitbit’s background sync can be aggressive about saving battery, so it might not realize you've moved 3,000 miles.
You’ve got to open the app.
If you find that your Fitbit constantly fails to update while traveling, check your location permissions. If the Fitbit app doesn't have "Always Allow" access to your location, it might struggle to trigger the automatic time zone switch. It’s a privacy trade-off, sure, but it’s the price of an accurate clock.
The Troubleshooting Rabbit Hole: What If Nothing Works?
Sometimes, a simple sync won't cut it. You’ve toggled the settings, you’ve restarted your phone, and the time is still hallucinating.
The Restart Trick
Every Fitbit has a specific restart sequence. For the Charge series, it usually involves plugging it into the charger and holding the button for 8-10 seconds until the Fitbit logo pops up. For the Versa or Sense, you hold the side button for about 10 seconds. This doesn't delete your data—it just reboots the OS. Think of it like splashing cold water on the tracker's face.
Logging Out
Actually log out of the Fitbit app. I know, it’s a pain to remember your password, but logging out and logging back in forces the app to re-establish its connection with Fitbit’s servers. This can clear out cached time data that might be "sticking."
Check Your "Set Automatically" Phone Settings
Believe it or not, the culprit is often the phone, not the watch. Go into your iPhone or Android system settings.
- iOS: Settings > General > Date & Time.
- Android: Settings > System > Date & Time.
Make sure your phone is set to pull time from the network. If your phone is off by even thirty seconds, the Fitbit sync might fail or produce errors.
Why Your Fitbit Refuses to Sync
You can't adjust the time if the device won't talk to the app.
Bluetooth interference is real. If you’re surrounded by other Bluetooth devices—tablets, speakers, your partner's tracker—the signal can get crowded. Try moving to another room. Also, check if your Fitbit is connected to multiple devices. If you have the app installed on an iPad and an iPhone, they might be fighting over who gets to talk to the watch. Turn off Bluetooth on the device you aren't using.
Another weird fix? Check your battery. If your Fitbit is below 10%, it might stop syncing to preserve enough power just to keep the sensors running. Give it a quick charge and try the time adjustment again.
Real-World Nuance: The "All-Day Sync" Factor
In the app settings, there used to be a toggle called "All-Day Sync." In newer versions of the app, this has been integrated differently, but the principle remains. For the time to stay perfectly accurate, your tracker needs frequent "check-ins" with the app. If you’re seeing the time drift by a few minutes over a week, it means your device isn't syncing often enough.
Keep the app open in the background. Don't "swipe up" to kill the app on your phone. If you kill the app, you kill the link.
Actionable Steps for a Permanent Fix
If you are staring at the wrong time right now, follow this exact sequence to get back on track:

- Force a Sync: Open the app and pull down on the home screen.
- Toggle Time Zones: In the app, go to Settings > App Settings > Time Zone. Turn off "Set Automatically," pick a random time zone, sync, then turn "Set Automatically" back on and sync again. This "shrubbing" of the setting usually forces a refresh.
- Check Bluetooth: Turn your phone's Bluetooth off for 10 seconds, then back on.
- Restart the Tracker: Use the specific button combo for your model (usually a 10-second hold).
- Verify Phone Time: Ensure your smartphone is set to "Provided by Network."
Once these steps are completed, the time on your wrist should match the time on your phone perfectly. If it still doesn't, your last resort is "Unpair and Repair." Remove the Fitbit from your Bluetooth settings and the app, then set it up as if it were a brand-new device. It takes five minutes but fixes 99% of persistent software bugs.
