How to Fix Date and Time on Mac

Why the date and time may be wrong on Mac?

A clock that drifts isn’t random—there’s usually a simple cause behind it. We’ve analyzed and compiled the most common reasons your Mac has the wrong date and time below—check it out.  

1. Automatic date and time sync is not working

Your Mac normally checks the time with an online time server and quietly corrects itself. When that handshake fails, the clock stops keeping pace and slowly falls behind. If you notice your Mac's date and time not updating on its own, the automatic date and time not updating sync is the first thing to check.

2. Wrong time zone is selected

Sometimes the clock works fine—it’s just set to the wrong place. If your Mac thinks it’s in another city, it’ll show that city’s time instead of yours. This often happens after travel or a fresh setup.

3. Location services are disabled

To set your time zone on its own, macOS needs to know roughly where you are. If Location Services are switched off, it can’t detect your region, and the automatic time zone option simply won’t work.

4. Wrong region is set

Your region settings shape how dates and times are displayed—the order of day and month, the 12- or 24-hour format, and more. If the region doesn’t match where you live, the display can look off even when the time itself is correct.

5. Network or time server issues

A shaky internet connection or a busy time server can stop your Mac from syncing. Since the clock relies on reaching that server, a dropped connection leaves it guessing. We recommend refreshing your connection or resetting network settings to clear this up.

Why accurate date and time matter on Mac?

An accurate clock is one of those quiet things you only notice when it breaks. It keeps your menu bar far more in order. Moreover, it guarantees the following:

• Secure connections. Websites use the date to check security certificates, so a wrong clock can block pages or trigger warnings.
• Accurate calendar reminders. Are you up for notifications that fire at the right moment, not an hour early or a day late?
• Messages, emails, and files saved appropriately. Get alll with the correct timestamp, which keeps everything in the right order.
• App logins and syncing. Since many services compare your time with theirs before letting you in, this is important.

In short, we’d say that a correct clock keeps your Mac talking smoothly with the rest of the internet.

How to fix wrong date and time on a Mac?

Below, we’ve listed a few practical ways to change the date and time on a MacBook and keep them correct. Start at the top and work down!

A quick overview of the key methods:

A note from our experts: 

 

The security of your daily operations on Mac is no less important than maintaining consistent date and time. For this reason, we suggest using MacKeeper’s Antivirus to easily detect and remove malware and other malicious threats from your computer quickly and safely.

 

Here are our guidelines on how to use MacKeeper's Antivirus:

1. Download MacKeeper, install the app, and open it.
2. Choose Antivirus from the list of features.
3. Click the Enable button and confirm to Start Scan.
4. Wait until MacKeeper finishes the job. If anything found, remove any detected threats with the Delete button.

1. Restart your Mac

A restart is the simplest first move, and it fixes more than people expect. It clears stuck processes that can quietly knock the clock out of step. Taking a moment to reboot a MacBook often puts the date and time right on its own, and here’s what to do:

1. Click the Apple menu in the top-left corner.
2. Select Restart.
3. Check the clock once your Mac wakes up.

2. Turn on automatic date and time

When this is on, macOS quietly keeps the clock right using an online source. It’s the easiest way to set date and time on MacBook and forget about it. Let’s make sure it’s switched on:

1. Open the Apple menu and choose System Settings.
2. Click General in the sidebar, then Date & Time.
3. Turn on Set time and date automatically.
4. If it’s already on, switch it off and back on to nudge a fresh sync.

3. Change the time server

Your Mac asks a time server for the exact time, with Apple’s set as the default. If that source is slow or unreachable, re-entering it gives the connection a clean restart. Do the following:

1. Go to System Settings > General > Date & Time.
2. Click Set next to Source.
3. Select Default, then click Done.

4. Check for macOS updates

Some clock glitches are simply software bugs that Apple has since ironed out. In this case, we suggest installing the latest macOS update to clear them while keeping your Mac on a secure version. Just follow our instructions:

1. Open System Settings > General > Software Update.
2. Wait a moment while your Mac checks for any available updates.
3. If an update is offered, click Update Now and follow the prompts.

5. Check time zone settings

If the clock is accurate but the hours are off, the time zone is the usual suspect. You can let macOS detect it or pick the closest city yourself. Here’s how:

1. Go to System Settings > General > Date & Time.
2. Turn on Set time zone automatically using your current location.
3. If the zone still looks wrong, switch it off, click Closest City, and choose the right one.

6. Enable Location Services for time zone detection

Automatic time zone detection only works when macOS can sense your location. A quick toggle in your privacy settings gets it talking again. Here’s what to do:

1. Open System Settings > Privacy & Security > Location Services.
2. Turn on Location Services.
3. Scroll to the bottom, click Details next to System Services.
4. Turn on Setting time zone, then click Done.

7. Check language and region settings

When the time is right but the format looks odd—the day and month swapped, let’s say—your region setting is doing it. Matching it to where you live tidies the display. Follow our hints below:

1. Open System Settings > General > Language & Region.
2. Set Region to your current country.
3. Check the Date and Time previews near the bottom to confirm they look right.

8. Sync the time using Terminal

When the usual settings won’t budge, a single Terminal command can force your Mac to refresh the time from a server. It sounds technical, but, believe us, it’s just a bit of copy and paste. The open Terminal shortcut makes it quick to get started, so do this:

1. Open Terminal from your Applications > Utilities folder.
2. Type sudo sntp -sS time.apple.com and press Return.
3. Enter your admin password when asked, then press Return to finish.

9. Set the date and time manually

If you’re offline or syncing simply won’t work, you can type the time in yourself. It’s a handy stopgap until automatic updates are back. Just do the following:

1. Go to System Settings > General > Date & Time.
2. Turn off Set time and date automatically.
3. Click Set, then type the correct date and time and confirm.

What to do if the problem with date and time on Mac keeps coming back?

If the clock drifts again after every fix, something deeper is nudging it. To settle it for good, our team leaves a few recommendations for you:

• Keep both Set time and date automatically and Set time zone automatically switched on.
• Install macOS updates as they arrive, since they often carry quiet fixes.
• If a Mac stays on for weeks, a clock that drifts can point to an aging internal battery worth checking with Apple.

Conclusion

A MacBook date and time wrong is usually a quick toggle away from being fixed. Once it’s right, keep things safe too—MacKeeper’s Antivirus scans for threats in real time. See how you can run your first scan in one click and remove anything suspicious if found.
