All in JS

The dateObject now contains the current date that can be used in various ways. 

Simply by using the predefined method like getDay(), getMonth()  and getFullYear(). For example, if you want to output the standard international date format YYYY-MM-DD (defined in ISO 8601 standard), just use something like:

var year = dateObject.getFullYear();

var month = dateObject.getMonth();

var day = dateObject.getDay();

var output =  year + '-' + month + '-' + day; 

Looks really to much code for a standard date format but you get the point. There is also a quicker way by just using a substring of the toISOString() method:

var output = dateObject.toISOString().substring(0,10);

I most cases you should display a date format that the user understands and not your preferred format. There is a cool method called toLocaleDateString().

var output = dateObject.toLocaleDateString();
