thank you

i've learn vagaries of js date(), put fiddle.

it uses standard js data manipulation through series of functions you'll able figure out easily.

what i'm not sure of mean "month" "two months" , "six months" - i've assumed month 4 week period, , not calendar month.

edit: re-read text , i'll work on definition of month.

here js functions:

function adddays(anydate1, daystoadd) {   var mydaystoadd = daystoadd;   var daysadded = anydate1.getdate() + mydaystoadd;   return new date( anydate1.setdate( daysadded ) ); }  function startofweek( anydate ) {   localdate = anydate;   daydifference = 0;   daydifference = localdate.getdate() - numericdayofweek( localdate );   return new date( localdate.setdate( daydifference ) );   }  function textdayofweek(mydate) {   var dayarray = ['sunday', 'monday', 'tuesday', 'wednesday', 'thursday', 'friday', 'saturday'];   return dayarray[ numericdayofweek(mydate) ]; }  function numericdayofweek( anydate7 ) {   var localdate = anydate7;   return localdate.getday(); }  function todayfull()  {   return new date(); }  function todayshort( mydate3 ) {  localdate = mydate3;  thedate =  (localdate.getmonth() + 1) + '/' +    localdate.getdate() + '/' +    localdate.getfullyear();   return thedate; }
