Using countdown template without items & animations?

@... Here is a stripped version of the countdown script I modified a little that you can use:

// -----JS CODE-----

// @input Component.Text remainingDateText

// @ui {"widget":"group_start", "label":"Countdown"}
// @input int month = 1  {"widget":"combobox", "values":[{"label":"January", "value":1}, {"label":"February", "value":2}, {"label":"March", "value":3}, {"label":"April", "value":4}, {"label":"May", "value":5}, {"label":"June", "value":6}, {"label":"July", "value":7}, {"label":"August", "value":8}, {"label":"September", "value":9}, {"label":"October", "value":10}, {"label":"November", "value":11}, {"label":"December", "value":12}]}
// @input int day = 1 {"widget":"slider", "min":1, "max":31, "step":1}
// @ui {"widget":"group_start", "label":"Countdown Message"}
// @input string customMessage = "Until my birthday" { "label":"Text" }
//@input bool singleLine
//@input Component.Text messageText { "label":"Message Text", "showIf": "singleLine", "showIfValue": false}
// @ui {"widget":"group_end"}
// @ui {"widget":"group_start", "label":"Reveal Message"}
// @input string setDateMessage = "YAY!" { "label":"Text"}
// @ui {"widget":"group_end"}
// @ui {"widget":"group_end"}

setCustomDateAndMessage(); 

function setCustomDateAndMessage() {

    var remainingDays = calculateRemainingDays();

    if (remainingDays != 0) {
        if (script.messageText) {
            script.messageText.text = script.customMessage;
        }

        if (remainingDays == 1) {
            if (script.singleLine) {
                script.remainingDateText.text = remainingDays + " DAY " + script.customMessage;
            } else {
                script.remainingDateText.text = remainingDays + " DAY";
            }
        } else {
            if (script.singleLine) {
                script.remainingDateText.text = remainingDays + " DAYS " + script.customMessage;
            } else {
                script.remainingDateText.text = remainingDays + " DAYS";
            }
        }
    } else {
        script.remainingDateText.text = script.setDateMessage;
//            script.remainingDateText.size = onSetDateFontSize;
        if (script.messageText) {
            script.messageText.enabled = false;
        }
    }
}

function calculateRemainingDays() {

    var today = roundedDate(new Date());

    var month = script.month;

    var yearWithLeapDay = 4;

    var day = Math.min(script.day, daysInMonth(month, yearWithLeapDay));

    var customUserDate = roundedDate(new Date());

    customUserDate.setMonth(month - 1, day);

    // Leap day
    if (month == 2 && day == 29) {
        customUserDate = findNextLeapDay(today);
    }

    var daysRemaining = dateDiff(today, customUserDate);

    if (daysRemaining < 0) {
        customUserDate.setFullYear(today.getFullYear() + 1);
        daysRemaining = dateDiff(today, customUserDate);
    }
    return daysRemaining;
}

function dateDiff(current, inputDate) {
    return Math.round((inputDate - current) / (1000 * 60 * 60 * 24));
}

// 1-index based month
function daysInMonth(month, year) {
    return new Date(year, month, 0).getDate();
}

// Is it a leap year?
function isLeapYear(year) {
    return ((year % 4 == 0) && (year % 100 != 0)) || (year % 400 == 0);
}

function findNextLeapDay(startDate) {
    var date = roundedDate(startDate);
    var year = date.getFullYear();
    if (date.getMonth() > 1) {
        year += 1;
    }
    while (!isLeapYear(year)) {
        year += 1;
    }
    date.setFullYear(year);
    date.setMonth(1, 29);
    return date;
}

function roundedDate(date) {
    var roundedDay = new Date();
    roundedDay.setFullYear(date.getFullYear());
    roundedDay.setMonth(date.getMonth(), date.getDate());
    roundedDay.setHours(0);
    roundedDay.setMinutes(0);
    roundedDay.setSeconds(0);
    roundedDay.setMilliseconds(0);
    return roundedDay;
