How to Change the Time on Your Fitbit
Getting the time wrong on your Fitbit is more than a minor annoyance — it throws off your sleep tracking, workout logs, and reminder schedules. The good news is that Fitbit devices are designed to sync time automatically, but there are several reasons that sync might not happen the way you expect. Understanding how time works on Fitbit — and what controls it — saves you from chasing the wrong fix.
How Fitbit Handles Time (It's Not Manual by Default)
Unlike a traditional watch, Fitbit devices don't have a built-in clock that you set independently. Instead, your Fitbit pulls its time from the Fitbit app on your paired smartphone. When your device syncs with the app, it updates the time automatically based on what your phone reports.
This means:
- Your Fitbit's time is only as accurate as your phone's time
- Time zone changes on your phone should flow through to your Fitbit after a sync
- If you haven't synced recently, your Fitbit might be showing stale time data
This design keeps things simple in most cases — but it also means the solution to a wrong time is usually found in the app or your phone's settings, not on the device itself.
Step 1: Force a Manual Sync
The fastest fix for an incorrect time display is triggering a sync between your Fitbit and the app.
To sync manually:
- Open the Fitbit app on your iOS or Android phone
- Tap the Today tab (the icon at the bottom left)
- Tap your profile picture or device image at the top
- Select your Fitbit device
- Pull down on the screen to initiate a sync, or tap Sync Now if that option appears
Once synced, check your Fitbit's time display. In most cases, this resolves the issue immediately.
Step 2: Check Your Phone's Time Settings
Since your Fitbit mirrors your smartphone's time, your phone needs to be showing the correct time first.
On iPhone:
- Go to Settings → General → Date & Time
- Enable Set Automatically — this pulls time from your carrier's network
On Android:
- Go to Settings → General Management → Date and Time (exact path varies by manufacturer)
- Enable Automatic date and time
If your phone was set to a manual time or the wrong time zone, correcting it there and then syncing your Fitbit should bring everything into alignment. 🕐
Step 3: Verify Your Time Zone in the Fitbit App
Your Fitbit app has its own time zone setting, and it doesn't always update automatically — especially after travel.
To check and update time zone:
- Open the Fitbit app
- Tap your profile picture → App Settings
- Scroll to find Time Zone
- Make sure it's set to your current location, or toggle Set Automatically if that option is available
This is a commonly missed step. Even if your phone shows the right time, a mismatched time zone in the Fitbit app can cause your device to display the wrong hour.
Clock Face and 12-Hour vs. 24-Hour Format
Separate from the actual time, you might also want to change how time is displayed on your Fitbit — switching between a 12-hour and 24-hour (military time) format.
To change the clock format:
- Open the Fitbit app
- Go to your device settings (via your profile)
- Select Clock Display Time or Clock Face settings, depending on your model
- Choose between 12-hour or 24-hour format
Not every Fitbit model surfaces this setting in the same place, and some clock faces override the format setting entirely — a clock face designed for 24-hour display will show 24-hour time regardless of your preference.
Variables That Affect Time Accuracy on Fitbit
Not every Fitbit user experiences this the same way. Several factors determine how reliably your device keeps accurate time:
| Variable | How It Affects Time Accuracy |
|---|---|
| Sync frequency | Less frequent syncing means more potential drift |
| Fitbit model | Newer models with GPS may have more reliable time updates |
| Phone OS version | Older OS versions may have Bluetooth sync inconsistencies |
| App version | Outdated Fitbit app versions can introduce sync bugs |
| Travel/time zones | Crossing zones requires manual sync or auto-detection |
| Clock face selected | Some third-party clock faces display time differently |
Fitbit models also vary in how they handle GPS and connectivity. Devices with built-in GPS (like the Fitbit Charge 6, Sense 2, or Versa 4) can acquire time signals more directly during outdoor workouts, while earlier models depend entirely on phone sync.
When a Sync Doesn't Fix It 🔧
If you've forced a sync and checked both your phone's time settings and the Fitbit app's time zone, but the time is still wrong, a few additional steps are worth trying:
- Restart your Fitbit: Hold the button(s) on your device until it restarts. The method varies by model — check Fitbit's support documentation for your specific device.
- Log out and back into the Fitbit app: This forces the app to re-establish its connection and settings.
- Reinstall the Fitbit app: A fresh install can resolve persistent sync issues caused by corrupted app data.
- Check for firmware updates: An outdated firmware version on the device itself can occasionally cause time-related bugs. The Fitbit app will prompt you if an update is available.
The Part That Depends on Your Situation
Most Fitbit time issues resolve with a sync or a quick time zone correction. But the exact steps that matter most depend on which Fitbit model you have, which phone OS you're running, how often your device syncs, and whether you've recently traveled or changed your phone.
A Fitbit Inspire 2 paired to an older Android phone behaves differently than a Sense 2 connected to a current iPhone — and what fixes it for one user may not be the right starting point for another. Your device generation, app version, and daily sync habits are the variables that determine which of these steps actually applies to your setup.
