Hi All,
I need to compare a date of Aug 31st, and a year against today's date
and the below does give me Aug 31st, it gives me Aug 1st,

   var dteLimit = new Date();
  alert('Initial Setting');

   dteLimit.setDate(30);  ----gives Aug 30
   dteLimit.setDate(14);  ----gives Aug 14
   dteLimit.setDate(31);  ----Does NOT give Aug 31

it tries to set 31 for nov which will be dec 1

after that you set month as aug so you see aug 1

set the month first and then the date

Good answer guys!  Just to add a little follow up the same principle is true if you are setting the year.  Make sure you do that first before any changes to month or day.  It won't always matter but can make a big difference at times, especially in February. :)
