If you are running your app in the browser, the browser’s language setting controls how data values are displayed. This include prices, decimals, date, times, etc.
I am going to assume that you are running Chrome on Windows.
Change the language of your Chrome browser (Windows & Chromebook only) You can set Chrome to show all settings and menus in the language you want. This option is only available on Windows and Chromebook computers.
On Mac or Linux? Chrome will automatically display in the default system language for your computer.
On your computer, open Chrome. At the top right, click More More and then Settings. At the bottom, click Advanced. Under “Languages,” click Language. Next to the language you’d like to use, click More More. If the language isn’t listed, add it by clicking Add languages. Click Display Google Chrome in this language or Display Chrome OS in this language.
This option is only available on Windows and Chromebook computers. Restart Chrome to apply the changes.
