Elapsed Time AngularJS Filter

elapsed.filter.js

// {{ dateString | elapsed }}

angular.module('elapsedFilter', [])
.filter('elapsed', function(){
    return function(date){
        if (!date) return;
        var time = Date.parse(date),
            timeNow = new Date().getTime(),
            difference = timeNow - time,
            seconds = Math.floor(difference / 1000),
            minutes = Math.floor(seconds / 60),
            hours = Math.floor(minutes / 60),
            days = Math.floor(hours / 24);
        if (days > 1) {
            return days + " days ago";
        } else if (days == 1) {
            return "1 day ago"
        } else if (hours > 1) {
            return hours + " hours ago";
        } else if (hours == 1) {
            return "an hour ago";
        } else if (minutes > 1) {
            return minutes + " minutes ago";
        } else if (minutes == 1){
            return "a minute ago";
        } else {
            return "a few seconds ago";
        }
    }
})

Awesome. Thank you!

Here is my variation of your code:

angular.module('app', []).filter('elapsed', function($filter){
    return function(date){
        if (!date) return;
        var time = Date.parse(date),
            difference = (new Date()) - time;

        // Seconds (e.g. 32s)
        difference /= 1000;
        if (difference < 60) return Math.floor(difference)+'s';

        // Minutes (e.g. 12m)
        difference /= 60;
        if (difference < 60) return Math.floor(difference)+'m';

        // Hours (e.g. 5h)
        difference /= 60;
        if (difference < 24) return Math.floor(difference)+'h';

        // Date (e.g. Dec 2)
        return $filter('date')(time, 'MMM d');
    };
});

Thanks dear
