By default, numbers and dates appear with USA regional formatting, and all content appears in English.
You can change the format of numbers and dates, and the language of app content.
Numbers
Change the format of numbers in the interface by changing your locale setting. Your settings do not affect other users; locale settings are unique for each user.
Dates
Change the format of dates in the interface by changing your locale setting and date field settings. If you set a date field to use locale settings to determine display format, it affects all users. The date format appears according to each user's locale setting.
Language
Change the language that appears in app content by changing your locale setting. Translated content affects all users in the same regional locale.
