Question

In my web-site I am getting a date from user which in format like “dd-mm-yyyy”,now I want to get the date which is 7-day before of that user’s date.
I am able to get the current date in format “dd-mm-yyyy” but how would I know the date which is one week before user’s date in javascript?

Answer 1

Try this–

 var MyDate = new Date('11/30/2012');  //date format in mm/dd/yyyy
 MyDate.setDate(MyDate.getDate() -7)
 var newDate = MyDate.getMonth()+1 + '/' + MyDate.getDate() + '/' +    MyDate.getFullYear()
 alert(newDate);

Note- subtracting seven days to a date shifts the month or year and the changes are handled automatically by the Date object.
