Change the date in the Fitbit app on your phone
The fastest way to fix your Fitbit's date is through the Fitbit mobile app. Open the app, tap your profile icon in the top left corner, then select your device from the list. Scroll down to find "Date & Time" and toggle it on if it is off. If the toggle is already on, the app is set to sync automatically with your phone's time — which means your Fitbit should show the correct date as long as your phone does.
If the date is still wrong after toggling the setting, try turning it off, waiting five seconds, then turning it back on. This forces the app to resync with your device. Close the Fitbit app completely and reopen it to confirm the change took effect. Most Fitbit models update within a few seconds of this step.
Key Takeaways
- The Fitbit app syncs your device's date automatically when "Date & Time" is toggled on in your device settings.
- If the date is wrong, toggle the setting off and back on to force a resync between your phone and Fitbit.
- Your Fitbit pulls the correct date from your phone, so check that your phone's date and time are set correctly first.
- Restarting the Fitbit app or restarting your phone can fix date sync problems that toggling does not resolve.
Check your phone's date and time first
Your Fitbit does not have its own internal calendar — it reads the date from your phone. If your Fitbit shows the wrong date, your phone's date is probably wrong too. Go to your phone's Settings app, find "Date & Time," and confirm the date is correct. Make sure "Automatic date & time" is toggled on so your phone updates itself when you move between time zones.
Once your phone's date is correct, open the Fitbit app and let it sync. This usually takes less than a minute. If your Fitbit still shows the old date, move to the next step.
Restart the Fitbit app or your phone
Sometimes the sync between your phone and Fitbit gets stuck. Close the Fitbit app completely — on iPhone, swipe up from the bottom of the screen and swipe the Fitbit app away; on Android, open Settings, go to Apps, find Fitbit, and tap "Force Stop." Wait 10 seconds, then reopen the app and let it sync again.
If that does not work, restart your phone entirely. Power it off, wait 30 seconds, and turn it back on. Once your phone is running again, open the Fitbit app and check whether the date has updated on your device. A full phone restart clears temporary glitches that can prevent syncing.
Unpair and repair your Fitbit if the date will not sync
If you have tried toggling the date setting, restarting the app, and restarting your phone and the date is still wrong, unpairing and repairing your device can reset the connection. In the Fitbit app, go to your profile, select your device, scroll to the bottom, and tap "Unpair This Device." Confirm the action.
After unpairing, restart your phone, then open the Fitbit app and pair your device again from scratch. The app will walk you through the pairing process. Once pairing is complete, your Fitbit should pull the correct date from your phone automatically. This step erases any stored data on your Fitbit, so make sure your data has synced to the app before you unpair.
Manually set the date on older Fitbit models
Some older Fitbit models — particularly the Fitbit Ionic and Fitbit Versa — allow manual date adjustment directly on the device. Swipe down from the top of your Fitbit's screen to open the quick settings menu. Look for "Settings," tap it, then find "Date & Time." You can adjust the date and time by hand using the device's buttons or touchscreen.
However, most newer Fitbit models do not have this option and rely entirely on syncing with your phone. If your device does not show a date setting in the quick menu, use the app method instead. Manual adjustment is useful only if your phone's date is correct but your Fitbit is not syncing properly.
Check your Fitbit's battery and connection
A Fitbit with a low battery may not sync properly, which can prevent date updates. Charge your device for at least 30 minutes using the charging cable that came with it. While it charges, keep your phone nearby so the app can maintain a Bluetooth connection.
After charging, open the Fitbit app and check the connection status. The app should show your device as "Connected" near the top of the screen. If it shows "Disconnected," your Fitbit may be out of Bluetooth range or the connection has dropped. Move your phone closer to your Fitbit and try syncing again. Once the connection is stable, the date should update.
Frequently Asked Questions
Why does my Fitbit show the wrong date even though my phone is correct?
Your Fitbit and phone may not be syncing properly. Toggle the "Date & Time" setting off and back on in the Fitbit app, then close and reopen the app. If that does not work, restart your phone or unpair and repair your device. A weak Bluetooth connection can also prevent syncing, so make sure your phone is within a few feet of your Fitbit.
Can I change the date directly on my Fitbit without using the app?
Most modern Fitbit models do not allow manual date changes on the device itself. Older models like the Ionic and Versa have a date setting in the device menu, but newer trackers rely entirely on syncing with your phone. Check your device's settings menu to see if the option is available, but the app method is the standard approach for all current models.
What happens if I unpair my Fitbit to fix the date?
Unpairing erases any data stored on your Fitbit device itself, but your historical data remains in the Fitbit app. Make sure your data has synced to the app before you unpair. After you repair your device, it will start fresh and pull the correct date from your phone automatically.
Does my Fitbit automatically update when I travel to a different time zone?
Yes, as long as your phone's "Automatic date & time" setting is on. When you travel and your phone updates to the new time zone, your Fitbit will sync and show the correct local time. If your phone is set to manual time adjustment, your Fitbit will not update until you change your phone's time.
