you can use onChange client script on both the date variable and determine the days and then show help text

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }

	// hide help text or field message

    var startDate = new Date(g_form.getValue('variable1'));
    var endDate = new Date(g_form.getValue('variable2'));

    // Calculate the difference in time (milliseconds)
    var timeDifference = endDate - startDate;

    // Convert the time difference to days
    var dayDifference = timeDifference / (1000 * 3600 * 24);

    if (dayDifference < 30) {
        // show help text or field message
    }
}

@abjaffrey 

seems issue because of date format

with which date format did you try?

I tried with YYYY-MM-DD and it gave me correct output as 9 days for 1st Jan and 10th Jan

try this updated script

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }

	// hide help text or field message

    var startDate = new Date(getDateFromFormat(g_form.getValue('variable1'), g_user_date_format));
    var endDate = new Date(getDateFromFormat(g_form.getValue('variable2'), g_user_date_format));

    // Calculate the difference in time (milliseconds)
    var timeDifference = endDate - startDate;

    // Convert the time difference to days
    var dayDifference = timeDifference / (1000 * 3600 * 24);

    if (dayDifference < 30) {
        // show help text or field message
    }
}
