Change how dates, times, and more appear on Mac
You can change the format used by your Mac and apps to display dates, times, numbers, currencies, and more.
On your Mac, choose Apple menu > System Settings, click General in the sidebar, then click Language & Region on the right. (You may need to scroll down.)
Click the pop-up menu next to Region, then choose a geographic region to use the region’s date, time, number, and other formats.
The formats that appear depend on the selected region and current language. See Change the language your Mac uses.
To customize formats, do any of the following:
Calendar: Choose the type of calendar used to display dates and times.
Temperature: Select the preferred temperature format, such as Celsius.
Measurement system: Select the preferred measurement system, such as Metric.
First day of week: Choose the first day of the week.
Date format: Choose the date format, such as day, then month, then year.
Number format: Choose the format for numbers, such as when a comma appears.
List sort order: Choose the sort order for names. This option is available only for some primary languages.
Term of address: Choose your preferred term of address (feminine, masculine, or neuter) to make your device feel more personal. Turn on “Share with all applications” so that all apps personalize how they address you. These options are available for these supported languages.
Tip: If you want to show the date in the menu bar or change how the time is shown, open Control Center settings, go to Menu Bar Only on the right (you may need to scroll down), then click Clock Options.
