browserLanguage. Here's a short script that displays the browser language. You can add it to any web page to see what language your browser is running under.
Here is what came up in my browsers:

toLocaleDateString(): Returns the date portion of a Date object as a string, using locale conventions
toLocaleTimeString(): Returns the time portion of a Date object as a string, using locale conventions
toLocaleString(): Returns both the date and time portions of a Date object as a string, using locale conventions
The following script shows the results of the three methods above when applied to today's date:

isNaN() method to test the validity of your date string against the browser's locale and react accordingly:
