        function app_ste_36098913_countdown_seconds_to_hr(seconds) {
            seconds = seconds || 0;
            seconds = Number(seconds);
            seconds = Math.abs(seconds);

            var d = Math.floor(seconds / (3600*24));
            var h = Math.floor(seconds % (3600*24) / 3600);
            var m = Math.floor(seconds % 3600 / 60);
            var s = Math.floor(seconds % 60);
            var parts = new Array();

            if (d > 0) {
                var dDisplay = d > 0 ? d + ' ' + (d == 1 ? "day" : "days") : "";
                parts.push(dDisplay);
            }

            if (h > 0) {
                var hDisplay = h > 0 ? h + ' ' + (h == 1 ? "hour" : "hours") : "";
                parts.push(hDisplay)
            }

            if (m > 0) {
                var mDisplay = m > 0 ? m + ' ' + (m == 1 ? "minute" : "minutes") : "";
                parts.push(mDisplay)
            }

            if (s > 0) {
                var sDisplay = s > 0 ? s + ' ' + (s == 1 ? "second" : "seconds") : "";
                parts.push(sDisplay)
            }

            return parts.join(', ', parts);
        }
