How to Change Time on Fitbit: Complete Step-by-Step Guide

Your Fitbit showing the wrong time usually comes down to one of two things: a missed sync or a mismatched time zone on your phone. I get this question more than almost any other, and my own watch has thrown the same tantrum after a long flight.

It sounds like a small glitch, but it throws off sleep tracking, alarms, and reminders that depend on an accurate clock.

Fitbit doesn’t run its own internal clock; every time zone setting and time change on Fitbit traces back to whichever app is paired with your device, whether that’s the Fitbit app or the newer Google Health app.

Below is the exact sync process, what changes after switching phones or traveling, how to flip between 12-hour and 24-hour display, and which deeper fixes are worth trying once the basic steps stop working.

How to Change the Time on Fitbit

Fitbit trackers and smartwatches don’t include an on-device clock menu. The time you see comes from whichever phone app is paired with your device, then syncs over. Correcting the display almost always starts with your phone, not the watch.

1. Check your phone’s own date, time, and time zone; this is the source everything else pulls from.
2. Turn on Bluetooth and keep your phone within a few feet of your Fitbit, since constant Bluetooth pairing can quietly drain your phone’s battery life.
3. Open the Fitbit app, or the Google Health app if your account has migrated over, and sign in.
4. From the Today tab, tap your profile picture or the settings icon in the top corner.
5. Select your Fitbit device from the connected devices list.
6. Touch and hold the screen, then pull down to force a sync, or use Sync Now under your device settings.
7. Give it a few seconds, then check the display on your Fitbit.

This clears up the majority of wrong-time complaints within a minute. If the clock still doesn’t match after a successful sync, the cause is almost always a time zone mismatch, not a syncing failure.

Quick Reference: Match Your Symptom to the Fix

Structural change: the original had two overlapping tables covering the same causes (missed sync, time zone, Bluetooth). Merged into one comprehensive table so nothing is explained twice.

Change Your Fitbit Time Zone Settings

If a manual sync didn’t fix the problem, your time zone settings are the next place to check. This matters most if you travel often or if your phone’s automatic time zone detection isn’t working as expected.

1. Let Your Phone Handle Time Zone Changes Automatically

If you cross time zones often, automatic detection saves you from resetting this manually every trip, a convenience worth having whether you’re using fitness band comparison gear or a full smartwatch. Your phone updates its own time zone by location, and your Fitbit picks up the change on the next sync.

• Android: Settings > Date & Time > enable automatic time zone.
• iPhone: Settings > General > Date & Time > enable Set Automatically.
• In the Fitbit or Google Health app, confirm Set Automatically is on under Time Zone, then sync.

2. Set the Time Zone Manually When Auto-Detection Misses

Automatic detection isn’t perfect; weak location signals, airplane mode, or restrictive phone permissions can all stop it from catching a new zone. Turn off Set Automatically, choose the correct city or region, then sync.

This manual override has fixed my own clock within a single sync attempt almost every time, even on an older fitness tracker; it’s the more reliable of the two methods, just less convenient day-to-day.

3. Catch Up After Traveling

Crossing time zones, or moving through a federally mandated clock change, can leave your Fitbit stuck on your old local time until it hears otherwise from your phone. After landing, check your phone’s time zone first, then run a sync.

If the clock hasn’t moved, toggle Bluetooth off and back on, then sync again. A stalled Bluetooth handshake, not the time zone setting itself, is the most common reason a Fitbit fails to catch up after a flight.

Switch Between 12-Hour and 24-Hour Display

If the time itself is already correct, synced ultimately from the same official U.S. time reference used across the country, but the format isn’t what you’re used to, this is a one-toggle fix, not a syncing issue.

Fitbit doesn’t tie the display format to your phone’s regional settings, so switching to 24-hour time, or back to 12-hour, has to be done manually inside the app rather than inheriting whatever your phone already shows.

The path is short: open App Settings, tap Date, time & units, select Clock Display Time, choose either 12-hour or 24-hour, then sync your Fitbit to push the change through.

I keep mine on 24-hour mostly out of habit from tracking workout splits, but either format behaves identically once it syncs; it’s purely cosmetic and won’t affect your recorded activity, sleep, or heart-rate data.

Why Fitbit Doesn’t Keep Its Own Clock

Most current Fitbit devices, including the Charge 6, Inspire 3, Sense 2, and Versa 4, don’t have a standalone real-time clock chip the way a traditional watch does.

Instead, they rely on Bluetooth Low Energy syncing with a paired phone to receive the current time, which is why a wrong clock is almost always a phone-and-sync issue rather than a hardware fault.

A small number of GPS-equipped models can pick up satellite time during an outdoor GPS workout, since each orbiting satellite carries onboard atomic clocks that broadcast precise time data, but that’s a byproduct of exercise tracking, not something you can rely on for everyday timekeeping.

Google has also been migrating Fitbit accounts over to the Google Health app, which runs the same underlying sync process but uses slightly different menu labels. If the steps above don’t quite match what’s on your screen, you’re likely already on the newer app.

Troubleshooting Deeper Sync and Connection Problems

Structural change: consolidated the old second table, the standalone firmware section, and scattered reset mentions into one flowing section instead of repeating the same causes in a second table.

Every fix above still comes back to the same principle: changing the time on Fitbit always routes through the paired app, never the device itself. When the basics don’t hold, work through these in order.

• Bluetooth keeps dropping: turn Bluetooth off and on, close and reopen the app, then sync again.
• App and account aren’t communicating: sign out, sign back in, and reconnect your device.
• Sync completes, but nothing changes: restart the Fitbit, then sync again.
• Outdated firmware: open your device settings in the app, check for an available update, install it, then sync.

Firmware updates quietly fix more time-related bugs than you’d expect. My own Fitbit ran fine for months, then started drifting a few minutes a day for no obvious reason; it turned out an update had been sitting there unapplied the whole time. Worth ruling out before you assume anything’s actually broken.

Does This Work the Same on Every Fitbit Model?

The phone-dependent clock applies across the current lineup: Charge 6, Inspire 3, Sense 2, Versa 4, and the newer Fitbit Air all pull time the same way.

If you’re still using an older Luxe, Google has scheduled that model’s software support to end in mid-2026, which can make syncing, and, by extension, the clock, less reliable going forward.

My own Charge 6 catches a sync almost instantly, but an older Versa I still keep around for testing takes a beat or two longer to grab a signal worth knowing before you assume something’s broken on an older device.

When to Try a Factory Reset

A factory reset can fix a stubborn clock, but it should always come last. Try these checks first, and treat the reset itself as a final, deliberate step.

• Confirm you’ve already tried a fresh manual sync and it still hasn’t fixed the time.
• Restart Bluetooth on your phone, then reconnect it to your Fitbit.
• Sign out of the Fitbit or Google Health app, then sign back in.
• Check for a pending firmware update and install it if one’s available.
• Sync one last time before resetting, so your latest activity data is saved.
• Reset the device, then re-pair it with the app and sync again.

Once you’ve re-paired and synced, the clock should hold going forward. If it doesn’t, the issue likely runs deeper than software and is worth flagging to Fitbit support.

Final Verdict

Correcting the time on a Fitbit almost never means something is broken; it’s the paired phone, the time zone setting, or a sync that never finished.

Following the steps here in sequence, starting with a basic sync and ending with a firmware check, clears out nearly every case without ever needing a factory reset.

Because the clock rides entirely on your phone’s connection rather than an onboard timer, the same logic holds whether you’re on a Charge 6, a Sense 2, a Versa 4, or an Inspire 3.

Frequently Asked Questions

Can a Fitbit Display Seconds?

Most Fitbit clock faces show hours and minutes only, though a few clock face options include a seconds display. Availability depends on which clock face you’ve selected on your device.

Can Fitbit Show Two Time Zones?

No, Fitbit devices display a single time zone based on your phone’s current location or manually selected setting. There’s no built-in way to view a second time zone alongside your local one.

Does Correcting Time Change Existing Activity Data?

No. Fixing the time on your Fitbit only affects how the current time is displayed going forward. It doesn’t alter or reorganize any activity, sleep, or step data already recorded.

Does Fitbit Adjust Automatically for Daylight Saving Time?

Yes, as long as your phone’s own time zone updates automatically for daylight saving, Fitbit picks up the change on its next sync. If your phone is set to a fixed time zone rather than automatic, you’ll need to manually trigger a sync once the clocks change.

Why Did My Fitbit’s Time Change Without Me Doing Anything?

This is normal, not a glitch. It usually means your phone’s automatic time zone detection kicked in during a routine sync, often after travel or a phone software update. If it landed on the wrong zone, turn off Set Automatically and pick the correct region yourself.
