It’s happened to all of us. You glance at your wrist after a long flight or a weekend where your battery hit zero, and suddenly you’re living in the wrong dimension. Or at least, the wrong time zone. Your Fitbit says it’s 2:00 PM when your phone clearly shows 5:00 PM. It’s annoying. Actually, it’s more than annoying because it messes up your sleep tracking, your step hourly goals, and those reminders to move that you probably ignore anyway.
Learning how to set time and date on Fitbit isn't actually about digging through a "clock" menu on the watch itself. That’s the big secret. Most people spend twenty minutes tapping their screen, getting increasingly frustrated because there is no "Set Time" button on a Charge 6, a Sense 2, or an Inspire.
The truth? Your Fitbit is a mirror. It doesn't have its own independent brain for timekeeping. It just reflects what your smartphone tells it. If the mirror is broken, you don't fix the glass; you fix the thing standing in front of it.
The Sync Is Your Best Friend
Ninety percent of the time, your Fitbit is wrong because it hasn't talked to your phone in a while. Bluetooth is finicky. We know this. If your app hasn't synced in twenty-four hours, the internal clock on the wearable can drift, or it might fail to recognize a Daylight Savings Change.
Open the Fitbit app on your iPhone or Android. Give that home screen a firm tug downward. You’ll see the little spinning icon at the top. This is the manual sync. If the sync finishes and the time jumps to the correct hour, you’re done. Easy. But honestly, it’s rarely that simple when things are actually broken. Sometimes the app says "Sync Complete" and the watch still insists it’s three hours behind. That is when you have to dive into the settings.
Changing Time Zones Manually
Maybe you’re traveling. Or maybe you’re a digital nomad jumping between Lisbon and New York. Your Fitbit should update automatically, but if it doesn't, you need to force its hand.
Inside the Fitbit app, tap your profile icon or the "device" icon in the top left corner. You’re looking for App Settings. Don’t go to the device settings yet; go to the app-wide settings. There’s a toggle there usually labeled "Set Automatically."
Turn it off.
It feels counterintuitive, I know. But by turning it off, you can manually select your time zone. Pick a random one—say, London—and then sync the watch. Then, switch it back to your actual time zone and sync again. This "handshake" often clears whatever cache error was holding the old time captive. It’s the classic "unplug it and plug it back in" move, just for software.
The Problem With 12-Hour vs 24-Hour Time
Some people hate military time. Others can't live without it. If you want to change how the clock looks, you can't do that in the app. You have to go to the Fitbit.com dashboard on a web browser. This is a weird quirk of the Google-owned ecosystem. Log in, go to the gear icon, click Settings, and find "Clock Display Time." Change it from 12-hour to 24-hour, hit submit, and then—you guessed it—sync your watch via the phone app.
When the Battery Dies and Stays Dead
If your Fitbit stays dead for a few days, the internal oscillator loses its place. Even after you charge it to 100%, it might show the exact moment it "died" three days ago.

This happens a lot with older models like the Versa 2 or the original Luxe. The hardware basically pauses. To fix this, a simple sync usually works, but occasionally you need to perform a "long restart." For most modern Fitbits, this involves plugging it into the charger and holding the side button for about 10 seconds until you see the logo. This doesn't wipe your data. It just forces the OS to reload and fetch a fresh timestamp from the Bluetooth bridge.
Android vs. iOS: The Background Data Battle
Android users often have a harder time keeping the correct time. Why? Because Android is aggressive about killing background apps to save battery. If your phone kills the Fitbit app process, the watch can't sync.
To prevent this, you have to go into your phone's battery settings and set the Fitbit app to "Unrestricted." If you don't, you'll be searching for how to set time and date on Fitbit every single morning because the app went to sleep while you were. iPhone users have it a bit easier with "Background App Refresh," but even then, if you "swipe up" and force-close the Fitbit app, the time-syncing connection dies instantly. Keep the app open in the background. It won't hurt your battery as much as you think.
Why Won’t My Fitbit Sync at All?
If you’ve tried the manual time zone change and the tug-to-sync, and nothing is happening, you might have a Bluetooth bond problem.
- Go to your phone’s Bluetooth settings.
- Find your Fitbit and "Forget This Device."
- Turn Bluetooth off and back on.
- Go back to the Fitbit app and "Set Up a Device."
It’ll recognize your watch is already there and re-establish the bond. This is usually the nuclear option for fixing time errors, but it works when the software gets stuck in a loop.
A Note on Daylight Savings
Every March and November, the Fitbit forums explode. "Why is my watch an hour off?" If your phone updated but your watch didn't, it's almost always a sync lag. Fitbit’s servers are handling millions of requests at once during these windows. Give it an hour. If it’s still wrong, the "Turn off Set Automatically" trick mentioned above is your fastest ticket back to reality.
Real-World Nuance: The "Clock Face" Variable
Believe it or not, sometimes it’s not the system time; it’s the clock face. Some third-party developers build clock faces that have bugs. They might hard-code a specific time zone or fail to update when the system time changes.
If you’re seeing the wrong time, try switching to a "Made by Fitbit" official clock face. If the time fixes itself, you know the fancy designer face you downloaded was the culprit. It's a small detail, but it saves a lot of troubleshooting time.
Actionable Steps for a Perfect Clock
To ensure your Fitbit stays accurate and you never have to worry about the date or time drifting again, follow this specific maintenance rhythm.
- Check the App Version: Ensure you are running the latest version of the Fitbit app from the Google Play Store or Apple App Store. Older app versions often struggle with time zone handshakes on newer OS versions.
- Force a Morning Sync: Make it a habit to open the app once a day. This ensures the watch’s internal clock stays calibrated with the atomic time on your phone.
- Toggle Bluetooth: If the time is wrong and a sync fails, toggle your phone’s Bluetooth off for 30 seconds. It clears the communication cache better than a restart sometimes.
- Verify Location Services: Fitbit needs your location (GPS) to be set to "Always" or "While Using" to correctly identify your local time zone. If you’ve denied location permissions, the app might default to UTC or your "home" time zone regardless of where you actually are.
- Restart the Tracker: If the screen shows a nonsensical date like January 1st, 1970 (the Unix epoch), your tracker's firmware has crashed. Connect it to power and hold the button until the logo appears to reset the hardware clock.
Staying on top of these small sync issues keeps your data clean. If the time is wrong, your calorie burn graphs and sleep stages will be shifted, making your health data essentially useless for that day. A quick thirty-second fix ensures your hard-earned steps actually count toward the right day.
