Your Fitbit is showing the wrong time. Maybe you traveled, just switched to daylight saving, or set up a new device and the clock never synced correctly. Whatever happened, it's a quick fix.

There are two ways to change the time on a Fitbit: let the app sync it automatically (which handles 99% of cases), or adjust it manually if you're running into a persistent issue. This guide covers both, along with how to switch time formats and troubleshoot common sync failures.

Key Takeaways

• Most Fitbit devices sync the time automatically from your phone when connected via Bluetooth

• You can't set the time directly on the Fitbit device itself. It pulls from your phone's clock

• If the time won't update, the fix is almost always a fresh Bluetooth sync or checking your phone's time zone settings

Method 1: Sync via the Fitbit App (The Standard Way)

Fitbit devices don't have a built-in clock you can set manually. They pull the time from your smartphone via Bluetooth. So the first thing to check is whether your phone and Fitbit are connected and synced.

Here's how to trigger a sync:

• Open the Fitbit app on your iPhone or Android phone

• Make sure Bluetooth is enabled on your phone

• Tap the Today tab at the bottom of the screen

• Pull down on the screen to trigger a manual sync

• Wait for the sync to complete (usually 10-30 seconds)

Once synced, your Fitbit pulls the time directly from your phone's clock. If your phone has the correct time, your Fitbit will too. That's all most people need to do.

Method 2: Fix Your Phone's Time Zone Settings

If the time is consistently wrong after syncing, the problem is usually your phone's time zone, not the Fitbit itself.

On iPhone:

• Go to Settings > General > Date & Time

• Turn on Set Automatically

• If it's already on, toggle it off, wait a few seconds, and toggle it back on

• Open the Fitbit app and sync again

On Android:

• Go to Settings > General Management > Date and Time (exact path varies by manufacturer)

• Enable Automatic date and time

• Enable Automatic time zone

• Open the Fitbit app and sync

After your phone's time is correct, a fresh sync in the Fitbit app will update your tracker within seconds.

How to Switch Between 12-Hour and 24-Hour Time Format

By default, most Fitbit devices display time in 12-hour format (AM/PM). If you prefer 24-hour format, you can change it in the Fitbit app:

• Open the Fitbit app

• Tap your profile picture in the top left

• Tap your device name

• Scroll down to Clock Face settings (or look for Advanced Settings on some models)

• Select your preferred time format (12-hour or 24-hour)

• Sync your device

Not all Fitbit models let you set this from the advanced settings screen. On some, the time format is determined by your phone's regional settings. If you don't see the option in the app, go to your phone's language and region settings and change the time format there.

Why Your Fitbit Shows the Wrong Time (and How to Fix It)

If your Fitbit is showing the right time zone but the wrong hour, or if it reverts to the wrong time after syncing, here are the most common causes:

• Bluetooth not connected: Your Fitbit can only sync when it's in Bluetooth range of your phone. Check that Bluetooth is on and the devices are paired in the Fitbit app.

• Outdated Fitbit app: An older version of the app can cause sync failures. Update the Fitbit app through your phone's app store, then sync again.

• Phone time zone set manually: If you've manually overridden your phone's time zone (not using automatic), Fitbit might be reading a stale value. Switch to automatic and re-sync.

• Device needs a restart: Restart your Fitbit by holding the button(s) for 10 seconds (exact method varies by model; check Fitbit's support page for your device), then sync again.

• Firmware out of date: An outdated firmware version occasionally causes sync issues. Allow any pending firmware updates in the Fitbit app to complete.

For most people, forcing a Bluetooth disconnect and reconnect, then triggering a fresh sync, resolves the issue. If your Fitbit consistently loses the correct time, it's worth checking whether the battery level is low. Some devices don't retain settings reliably when the battery drops below 20%.

Getting More from Your Fitbit Data

Fitbit does a solid job of tracking your daily activity, sleep, and heart rate. The limitation is that most people never connect that data to how they structure their day. You know you slept poorly, but your calendar still has three back-to-back meetings and a 2pm deadline.

Lifestack is an AI-powered daily planner built around wearable data. It reads your health metrics and helps you schedule tasks at times that match your actual energy levels, so your most demanding work lands in your best hours. For people who use fitness trackers like Fitbit to stay accountable, pairing it with a planner that understands recovery and energy is a natural next step.

Frequently Asked Questions

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

No. Fitbit devices do not have a standalone time-setting interface. The time is always synced from the connected smartphone via Bluetooth. You need the Fitbit app and an active Bluetooth connection to update the time.

Why does my Fitbit keep showing the wrong time after syncing?

The most common cause is your phone's time zone being set manually rather than automatically. Switch your phone to automatic date and time, then trigger a fresh sync. If the problem continues, try restarting your Fitbit device and re-pairing it with the app.

Does Fitbit update automatically for daylight saving time?

Yes, as long as your phone is set to update the time zone automatically. When daylight saving time changes, your phone's clock adjusts, and the next Fitbit sync will reflect that change. If your Fitbit doesn't update, check your phone's date and time settings and sync manually.

How do I change the time on a Fitbit Charge 6 or Sense 2?

The process is the same across all current Fitbit models: open the Fitbit app on your phone, ensure Bluetooth is connected, and sync. The Charge 6 and Sense 2 both pull time from the connected phone, so as long as your phone has the correct time and time zone, a sync will fix it.

What if my Fitbit shows a different time than my phone?

This means the last sync didn't complete successfully. Make sure Bluetooth is enabled on your phone, open the Fitbit app, and pull down to force a sync. If the time still doesn't match after syncing, restart both your phone and your Fitbit, then try again.

How do I set my Fitbit clock to show the date as well?

Most Fitbit models display date information through the clock face. Open the Fitbit app, tap your device, and select Clock Face. Choose a clock face that includes date display. The face you choose will appear on your device after the next sync. Some clock faces show only time, so look specifically for ones labeled with date or stats.
