Change the time through the Fitbit app on your phone

The fastest way to change your Fitbit's time is through the Fitbit app on your smartphone. Open the app, tap your profile icon in the top left corner, select your device, and scroll down to find "Time Zone" or "Clock Format." Tap it and choose your time zone from the list. The device syncs automatically once you save the change — you do not need to do anything else.

This method works for almost all Fitbit models, including Charge, Inspire, Sense, and Versa watches. The app handles the sync wirelessly, so your Fitbit updates within a few seconds of saving. If you do not see a time zone option in your device settings, your model may set time automatically based on your phone's location.

Key Takeaways

  • The Fitbit app on your phone is the main way to change time — open your profile, select your device, and tap "Time Zone."
  • Most Fitbit devices sync time automatically from your phone once you change the setting in the app.
  • If you travel across time zones, updating your time zone in the app will push the new time to your device within seconds.
  • Some older Fitbit models may require you to manually adjust the time through the device itself if the app does not show a time zone option.

What happens if your Fitbit time is wrong

An incorrect time on your Fitbit affects more than just telling time — it throws off your activity tracking and sleep records. Your Fitbit logs steps, heart rate, and sleep data tied to specific hours of the day. If the time is wrong, those records will be stamped with the wrong time, making your activity history confusing when you look back at it.

The device also uses time to calculate when you sleep and when you are active. A Fitbit that thinks it is 3 p.m. when it is actually 9 p.m. will not recognize your evening walk as evening activity, and your sleep data will be off by hours. Fixing the time corrects this going forward, though past records will keep their original timestamps.

Changing time on Fitbit watches with built-in screens

Fitbit Versa and Sense watches let you adjust time directly on the device if you prefer not to use the app. Swipe down from the top of the screen to open quick settings, tap the gear icon, scroll to "Time," and select your time zone. The watch updates when ready and syncs back to the app.

This method is useful if you are traveling and your phone is off or in airplane mode. The watch keeps its own time setting independent of the app, so you can change it on the device alone. However, the app method is still faster for most people because you only need to tap a few times on a larger phone screen.

Syncing after a time change

After you change the time zone in the Fitbit app, the device syncs automatically within a few seconds if Bluetooth is on and your phone is nearby. You do not need to manually sync or restart anything. Open the Fitbit app and look at your device name — if it shows a green checkmark or "synced" status, the change has gone through.

If your Fitbit does not update after a few minutes, try closing the Fitbit app completely and opening it again. Make sure Bluetooth is turned on in your phone's settings and that your phone and Fitbit are within 30 feet of each other. If the time still does not change, restart your Fitbit by holding the button on the side for 10 to 15 seconds until you see the Fitbit logo.

Changing time when you travel

When you travel to a new time zone, update your Fitbit's time zone in the app before you land or as soon as you turn your phone back on. This ensures your activity and sleep data for that day are logged in the correct time zone. If you forget and your Fitbit is still on the old time zone, change it as soon as you notice — your data from that point forward will be correct.

Some people keep their Fitbit on their home time zone even when traveling, which is fine if you prefer it that way. Just know that your activity log will show times that do not match the local time where you are. There is no right answer — it depends on whether you want your Fitbit to match your phone's time or stay consistent with home.

Fitbit models that set time automatically

Newer Fitbit models, including some Charge and Inspire versions, pull the time directly from your phone and update automatically whenever your phone's time changes. You do not need to do anything — the Fitbit stays in sync as long as Bluetooth is on. If you want to confirm your Fitbit is set to automatic time, open the app, go to your device settings, and look for an option that says "Automatic" or "Use phone time."

Older Fitbit models like the original Charge and some Flex versions may not have automatic time sync. For those devices, you have to change the time manually through the app each time you travel or when daylight saving time happens. Check your device manual or the Fitbit support website to see whether your specific model supports automatic time.

Frequently Asked Questions

Why does my Fitbit keep changing the time back?

If your Fitbit keeps reverting to the old time, your phone's Bluetooth may be disconnecting and reconnecting. Make sure Bluetooth stays on and your phone is near the device. If it keeps happening, try removing the device from your Bluetooth settings and re-pairing it through the Fitbit app. Restart both your phone and Fitbit if the problem continues.

Can I change the time on my Fitbit without the app?

On Fitbit Versa and Sense watches, yes — you can change the time zone directly on the device through the quick settings menu. On simpler models like Charge and Inspire, you need the app because the device itself does not have a settings menu. Check your device manual to see if your model has a built-in settings option.

What if the time zone I need is not in the list?

The Fitbit app shows all standard time zones recognized by your phone's operating system. If you cannot find your exact time zone, choose the closest one that matches your current local time. For example, if you are in a place that observes a half-hour offset, pick the time zone that is closest and adjust manually if needed.

Does changing the time affect my step count or heart rate data?

Changing the time zone does not erase or change your step count or heart rate numbers — it only changes the timestamp on those records. Your total steps for the day stay the same. However, if you look at your hourly breakdown, the hours will shift to match the new time zone.

How often do I need to update my Fitbit's time?

If your Fitbit syncs automatically from your phone, you never need to manually update it — it changes whenever your phone's time changes. If you have an older model, you need to update it when you travel across time zones or when daylight saving time happens in your area.
