A means to check if the date a user provided is invalid (like "April 31")
//Since JavaScripts counts months starting from 0 (January is 0),
//subtract 1 from the month integer submitted by the user

var testDate = new Date( userSubmittedYear,formattedMonth,userSubmittedDay,0,0,0,0) ;
if (
testDate.getFullYear() != userSubmittedYear
|| testDate.getMonth() != formattedMonth
|| testDate.getDate() != userSubmittedDay
