Change the language or regional formats used on iCloud.com
You can change the language and regional format settings (dates, times, numbers and currencies) used on iCloud.com.
Note: Changing these settings only affects iCloud.com. It does not affect settings for other websites, your web browser or other apps on your computer.
Change the language
On iCloud.com, go to Account Settings, click the current language, then choose a new language.
Change the date and other regional formats
You can change the regional formatting used to display dates, times, numbers and currencies on iCloud.com so it is different from the language used throughout iCloud.com. For example, if the language for iCloud.com is set to English but the regional formatting is set to Spain, dates in certain iCloud features appear in the format for Spain.
On iCloud.com, go to Account Settings, then click the current region below Formats.
Click the Formats pop-up menu, then choose a geographic region to use its date, time, number and currency formats.
To change the language used to display the formats, deselect “Make formats match language”, click the pop-up menu that appears, then choose a language.
