The fastest way to fix your Fitbit's date

The date on your Fitbit updates automatically when your device syncs with your phone — you do not need to change it manually in most cases. If your Fitbit is showing the wrong date after syncing, the problem is usually that your phone's date and time are incorrect, not the Fitbit itself. Check your phone's settings first, sync your Fitbit again, and the date should correct itself.

If you have an older Fitbit model or your device still shows the wrong date after syncing, you can adjust it through the Fitbit app on your phone. The steps differ slightly depending on whether you use an iPhone or Android phone, and whether your Fitbit is a tracker, watch, or smartwatch.

Key Takeaways

  • Your Fitbit's date syncs automatically from your phone, so check your phone's date and time settings first before assuming the Fitbit is wrong.
  • Most Fitbits cannot be adjusted directly on the device itself — you must use the Fitbit app on your phone to change the date.
  • The Fitbit app pulls the date from your phone's system settings, so correcting your phone's date will usually fix the Fitbit without any additional steps.
  • Some older Fitbit models have limited date-change options and may require unpairing and repairing the device to reset the date.

Check your phone's date and time first

Before you open the Fitbit app, verify that your phone is showing the correct date and time. Your Fitbit reads the date from your phone during sync, so if your phone's date is wrong, your Fitbit will be wrong too.

On iPhone: Open Settings, tap General, then tap Date & Time. Make sure "Set Automatically" is turned on. If it is already on, toggle it off and back on to force an update.

On Android: Open Settings, tap System or About Phone (depending on your phone model), then tap Date & Time. Turn on "Automatic Date & Time" if it is off. If it is already on, toggle it off and back on.

After you correct your phone's date, open the Fitbit app and sync your device. Press and hold the button on your Fitbit (or swipe down on a smartwatch) until you see the sync icon, then wait for the sync to complete. Your Fitbit's date should now match your phone.

Change the date through the Fitbit app on iPhone

If your phone's date is correct but your Fitbit still shows the wrong date, open the Fitbit app and navigate to your device settings. Tap the profile icon in the bottom right corner, then tap your device name.

Scroll down and look for "Date & Time" or "Time Zone" (the exact wording depends on your Fitbit model). Tap it, and you will see options to adjust the date manually. Some models let you change the date directly; others only let you set your time zone, which the device uses to calculate the correct date during the next sync.

After you make any changes, return to the main Fitbit app screen and sync your device again by pressing and holding the button on your Fitbit until the sync icon appears.

Change the date through the Fitbit app on Android

Open the Fitbit app and tap the profile icon in the bottom right. Select your device from the list of connected devices.

Scroll down to find "Date & Time" or "Time Zone" settings. Tap the option and adjust the date or time zone as needed. The exact menu structure varies by Fitbit model — some older trackers have very limited date options and may only let you change the time zone.

Once you have made your changes, go back to the main app screen and sync your device. On most Android phones, you can also swipe down from the top of the Fitbit app to trigger a manual sync.

What to do if the date keeps resetting

If you change the date but it reverts to the wrong date after syncing, your phone's date and time settings are overriding your manual change. This is normal behavior — your Fitbit is designed to trust your phone's system clock. Go back to your phone's Settings and make sure the automatic date and time setting is turned on and set to the correct time zone.

If your phone's date is correct and your Fitbit still will not hold the right date, try unpairing and repairing your device. In the Fitbit app, go to your device settings, scroll to the bottom, and tap "Forget This Device." Then open the Fitbit app fresh, tap the plus icon to add a device, and follow the pairing steps. This resets the device's connection to your phone and often fixes persistent date problems.

Fitbit models with limited date controls

Older Fitbit models like the Fitbit One, Fitbit Zip, and some Fitbit Flex versions have very basic date controls. These devices may not have a dedicated date-change option in the app — instead, they rely entirely on syncing with your phone to get the correct date.

If you own one of these older models and the date is wrong, the only reliable fix is to make sure your phone's date and time are correct, then sync your device. If that does not work, unpair and repair the device as described above. If the problem persists after that, the device's internal clock may be failing, and you may need to contact Fitbit support or consider replacing the device.

Frequently Asked Questions

Why does my Fitbit show the wrong date even though my phone is correct?

Your Fitbit may not have synced since you corrected your phone's date. Open the Fitbit app and manually sync by pressing and holding the button on your device until the sync icon appears. If the date still does not update after syncing, try toggling your phone's automatic date and time setting off and back on, then sync again.

Can I change the date directly on my Fitbit without using the app?

No. Fitbits do not have built-in menus to change the date on the device itself. You must use the Fitbit app on your phone. The device is designed to pull the date from your phone during sync, so the app is the only way to override that.

What if I change my time zone — will that change my Fitbit's date?

Changing your time zone will not change the date itself, only the time of day. Your Fitbit uses your phone's time zone to calculate what time it is, but the date comes from your phone's system date. If you travel and change your phone's time zone, your Fitbit will automatically adjust to show the correct local time during the next sync.

My Fitbit is paired to multiple phones — which phone's date does it use?

Your Fitbit uses the date from whichever phone it synced with most recently. If you sync with your iPhone in the morning and your Android phone in the evening, the Android phone's date will be what your Fitbit shows. To avoid confusion, keep the date and time the same on all phones you pair with your Fitbit.
