//Well, though this is a repeated question, 
//just to quench yo thirst, you can use javascript s RegExp for regular expressions.
//you can create one like:
var RegularExpression  =  new RegExp("pattern");
//or
var RegularExpression2  =  /pattern/;

//check for valid date format as:
var datePattern = /^w{3}[-]d{4}$/
//for numerical month value, u could use
//var datePattern = /^d{1,2}[-]d{4}$/
if(datePattern.test( my_date_string ))
   alert( correct )
else
   alert( false )

//or in a jquery way, if your date-holding element is an input with id as dateId
//then you can do:

if(datePattern.test($( #dateId ).val()))
   alert( correct )
else
   alert( false )
