You can’t set the time directly on a Fitbit tracker. The clock follows the time-zone and display settings in the Google Health app, and the tracker updates when it syncs with the app. To fix a wrong time after travel or a daylight-saving change, correct the time zone in the app and sync. To switch between 12-hour and 24-hour display, change the clock display setting in the same place and sync again.

Fix a wrong local time

A Fitbit usually shows the wrong time after you move to another time zone or when clocks change for daylight saving. Google’s Help Center for Google Health (checked October 2026) directs users to the app rather than the device, and the fix has two parts: confirm the time zone, then sync.

  1. Open the Google Health app.
  2. On the Today tab, tap your profile picture or initial, then tap Google Health settings.
  3. Under App Settings, tap Date, time & units, then tap Time Zone.
  4. If the automatically selected zone is wrong, turn off Set Automatically and choose the correct time zone from the list.
  5. Sync the Fitbit (see the sync section below).

If the time is still wrong after the sync, sign out of Google Health, sign back in, and sync again. This is the next official step in the Help Center’s instructions; if the time stays wrong after that, go to the troubleshooting section below.

Switch between 12-hour and 24-hour display

The clock format is a display preference, separate from the time zone. Changing it does not alter the time itself.

  3. Tap the arrows next to Clock Display Time and choose 12 hour or 24 hour.

Compare the two settings

Goal Where to change it What it affects Sync needed
Correct a wrong hour or date after travel or a clock change Date, time & units, then Time Zone The time the tracker displays Yes
Show 12-hour or 24-hour time Date, time & units, then Clock Display Time Only the clock format Yes

Sync the device

A sync pushes the app’s settings to the tracker and pulls your data back. Keep the Fitbit within range of your phone, then use either of these methods:

  • Open Google Health and pull down on the Today tab.
  • Open Connections and choose Sync.

Google Health states that devices also sync automatically when the app is opened while the device is nearby, so a time change often appears after you simply open the app.

If the time is still wrong

Google’s sync troubleshooting page lists an incorrect device time among the signs of a connection or sync problem. If the device is off by an hour or more, the Help Center points to its dedicated change-time article. Work through these checks in order:

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.
  • Confirm the Time Zone setting in the app matches your current location, with Set Automatically off if the automatic choice was wrong.
  • Make sure the Fitbit is near your phone and the app has permission to use Bluetooth on your phone.
  • Sign out of Google Health, sign back in, and sync again.
  • If none of these fixes the time, follow the current sync troubleshooting steps on Google’s Help Center rather than a device reset from older guides.

Device and menu variations

The official time-setting instructions do not separate the steps by Fitbit model. Google’s manuals index covers current and older families, including Charge, Sense, Versa, Inspire, and Luxe. Menu labels can still differ depending on app version, phone language, and whether you are signed in to a Google account, so if a label is missing, look for the closest match under Date, time & units or Google Health settings.
