Question

Hereby i am the following inputs:

Months to be separated by : 4 months

Will have the date with month and year: 07-05-2011.

Now i need to add months by 4 using JavaScript or jquery. How can this be done?

For example:

I am having the date as : 01-01-2011 and the duration is 4

My output should be:

01-12-2010

01-04-2011

01-08-2011

01-12-2011

For example if it is:

I am having the date as : 01-06-2011 and the duration is 4

My output should be:

01-06-2011

01-10-2011

01-02-2012

01-06-2012

Thanks in advance

Answer 1

Here you have:

var initialDate = new Date(2011, 5, 1); //Your example number two. January is 0
for(var i=0; i<4; i++){
  var newMonth = initialDate.getMonth() + i;
  var newYear = initialDate.getYear();
  if(newMonth >= 12){
     newMonth = newMonth % 12;
     newYear ++;
  }
  var newDate = new Date(newYear, newMonth, 1);
  alert(newDate);
}

Hope this helps. Cheers
