s-date
Same general purpose as moment.js, but in ~1kb minified.
This CommonJS module exports a single function that takes two parameters. The first is a format string, the second is an optional Date. If the date is omitted, it defaults to new Date();.
If you don't need full customizability for your date string, you probably don't need this library. Just use Date.toLocaleDateString() and related methods.
Usage
var date = require('s-date');
var myBirthday = new Date(1994, 10, 7);
date('{mm}/{dd}/{yyyy}', myBirthday); // '11/07/1994'Formatting options
Example: For January 2, 2053 4:30pm + 45 seconds
