//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')
