Hey,
I have really enjoyed building this package for Meteor:
https://atmospherejs.com/lbee/moment-helpers
It is a helpers package for using Moment.js so you can closely follow the Moment.js api inside your templates like {{moFormat someDateOrMomentObj 'YY-MM-DD HH:mm'}} would produce the same as moment(someDateOrMomentObj).format('YY-MM-DD HH:mm').
It has been awesome seeing people use the package and I have just updated it to v 1.1 and have implemented; Format, Time from now, Time from X, Difference and Calendar Time.
Let me know if you would like to see some other feature/s and I will see what I can do, I have posted the question as an issue also: https://github.com/lb-/moment-helpers/issues/22
I am also thinking of re-writing it in ECMAScript 2015 as suggested in the latest Meteor Blog:
We think anyone writing an app in JavaScript should be using ES2015. So we are making ES2015 the official JavaScript of the Meteor platform.
