moment-countdown
moment-countdown is a tiny Moment.js plugin that integrates with Countdown.js. The file is here. The NPM is moment-countdown
.
It's worth noting that the actual source is literally three lines of code, so if including this as a dependency is somehow annoying, you should consider reading it and just implementing it yourself or copying and pasting it into your app (you'll still need Countdown and Moment, natch).
How it works
//from then until now
moment("1982-05-25").countdown().toString(); //=> '30 years, 10 months, 14 days, 1 hour, 8 minutes, and 14 seconds'
//accepts a moment, JS Date, ISO-8601 string, or any other single arg taken my Moment's constructor
moment("1955-08-21").countdown("1982-05-25").toString(); //=> '26 years, 9 months, and 4 days'
//also works with the args flipped, like diff()
moment("1982-05-25").countdown("1955-08-21").toString(); //=> '26 years, 9 months, and 4 days'
//accepts all of countdown's options
moment().countdown("1982-05-25", countdown.MONTHS|countdown.WEEKS, NaN, 2).toString(); //=> '370 months, and 2.01 weeks'
See Countdown's documentation for descriptions of those extra options.

And you're off to the races.
