Regular expression (REGEX) for date validation
Dear friends,
here is a small but very usefull javascript based regex code to validate date in various formats Code:
<script type="text/javascript" language="javascript">
function isValidDate(prmDate) {
var re=/^(((0[1-9]|[12]\d|3[01])(\-|\/|\.)(0[13578]|1[02])(\-|\/|\.)((19|[2-9]\d)\d{2}))|((0[1-9]|[12]\d|30)(\-|\/|\.)(0[13456789]|1[012])(\-|\/|\.)((19|[2-9]\d)\d{2}))|((0[1-9]|1\d|2[0-8])(\-|\/|\.)02(\-|\/|\.)((19|[2-9]\d)\d{2}))|(29(\-|\/|\.)02(\-|\/|\.)((1[6-9]|[2-9]\d)(0[48]|[2468][048]|[13579][26])|((16|[2468][048]|[3579][26])00))))$/;
if (!re.test(prmDate)) {
return false;
} else {
return true;
}
}
</script>
Similarly for the date format MM/DD/YYYY and MM.DD.YYYY and MM-DD-YYYY, regex will be Code:
/^(((0[13578]|1[02])(\-|\/|\.)(0[1-9]|[12]\d|3[01])(\-|\/|\.)((19|[2-9]\d)\d{2}))|((0[13456789]|1[012])(\-|\/|\.)(0[1-9]|[12]\d|30)(\-|\/|\.)((19|[2-9]\d)\d{2}))|(02(\-|\/|\.)(0[1-9]|1\d|2[0-8])(\-|\/|\.)((19|[2-9]\d)\d{2}))|(02(\-|\/|\.)29(\-|\/|\.)((1[6-9]|[2-9]\d)(0[48]|[2468][048]|[13579][26])|((16|[2468][048]|[3579][26])00))))$/
Code:
/^((((19|[2-9]\d)\d{2}))(\-|\/|\.)(0[13578]|1[02])(\-|\/|\.)(0[1-9]|[12]\d|3[01])|(((19|[2-9]\d)\d{2}))(\-|\/|\.)(0[13456789]|1[012])(\-|\/|\.)(0[1-9]|[12]\d|30)|(((19|[2-9]\d)\d{2}))(\-|\/|\.)02(\-|\/|\.)(0[1-9]|1\d|2[0-8])|(((1[6-9]|[2-9]\d)(0[48]|[2468][048]|[13579][26])|((16|[2468][048]|[3579][26])00))(\-|\/|\.)02(\-|\/|\.)29))$/
