Answer 1

...or someone needs it in ColdFusion:

    
    

        var currentYear = arguments["year"];

        var a = floor(currentYear % 19);
        var b = floor(currentYear / 100);
        var c = floor(currentYear % 100);
        var d = floor(b / 4);
        var e = floor(b % 4);
        var f = floor((b + 8) / 25);
        var g = floor((b - f + 1) / 3);
        var h = floor((19 * a + b - d - g + 15) % 30);
        var i = floor(c / 4);
        var k = floor(c % 4);
        var l = floor((32 + 2 * e + 2 * i - h - k) % 7);
        var m = floor((a + 11 * h + 22 * l) / 451);
        var n = floor((h + l - 7 * m + 114) / 31);
        var p = floor(((h + l - 7 * m + 114) % 31) + 1);

        var month = n;
        if (len(month) lt 2) {
            month = "0" & month;
        } 

        var day = p;
        if (len(day) lt 2) {
            day = "0" & day;
        }

        var dateString = day & '.' & month & '.' & currentYear;

        return dateString;
