How to Change Date and Time on Mac Using Terminal
The date and time on your Mac play a crucial role in various aspects, from organizing your files to syncing with online services. While the system automatically sets the date and time, there may be instances where you need to manually adjust them. The Terminal app on your Mac provides a convenient way to modify the date and time settings. In this article, we will guide you through the process of changing the date and time using Terminal, along with a FAQs section to address common queries.
Changing the Date and Time Using Terminal:
Step 1: Launch Terminal
To open Terminal, go to Applications > Utilities > Terminal. Alternatively, you can use the Spotlight search by pressing Command + Space and typing “Terminal.”
Step 2: Accessing the “date” Command
In Terminal, type “date” without the quotes and hit Enter. This will display the current date and time on your Mac.
Step 3: Changing the Date
To modify the date, use the following command format: “sudo date MMDDHHMMYYYY” without the quotes. Replace MM with the month, DD with the day, HH with the hour, MM with the minute, and YYYY with the year you wish to set. For example, if you want to change the date to January 1, 2022, at 12:30 PM, the command would be “sudo date 010112302022.”
Step 4: Changing the Time
To adjust the time, use the following command format: “sudo date HHMM” without the quotes. Replace HH with the hour and MM with the minute you want to set. For instance, if you wish to change the time to 3:45 PM, the command would be “sudo date 1545.”
Step 5: Providing Administrator Password
After entering the date or time command, Terminal will prompt you to enter your administrator password. Type your password and press Enter. Note that your password will not be visible as you type.
Step 6: Verifying the Changes
To confirm that the date and time have been successfully changed, repeat Step 2 by typing “date” and pressing Enter. Terminal will display the new date and time you have set.
