Hi all...


<SCRIPT LANGUAGE="JavaScript">
function y2k(number) { return (number < 1000) ? number + 1900 : number; }

var reason = '';

function isValidDate (myDate,sep) {
// checks if date passed is in valid dd/mm/yyyy format

if (myDate.length == 10) {
if (myDate.substring(2,3) == sep && myDate.substring(5,6) == sep) {
var date = myDate.substring(0,2);
var month = myDate.substring(3,5);
var year = myDate.substring(6,10);

var test = new Date(year,month-1,date);

if (year == y2k(test.getYear()) && (month-1 == test.getMonth()) && (date == test.getDate())) {
reason = '';
return true;
}
else {
reason = 'valid format but an invalid date';
return false;
}
}
else {
reason = 'invalid spearators';
return false;
}
}
else {
reason = 'invalid length';
return false;
}
}

function tellMeIfInvalid(myDate) {
if (isValidDate(myDate,'/'))
document.write(myDate + ' = valid date<BR>');
else
document.write(myDate + ' = ' + reason + '<BR>');
}

tellMeIfInvalid('21/02/1999');
tellMeIfInvalid('2190291999');
tellMeIfInvalid('2/02/1999');
tellMeIfInvalid('21/2/1999');
tellMeIfInvalid('21/02/199');
tellMeIfInvalid('32/02/1999');
tellMeIfInvalid('21/02/1999');
</SCRIPT>
