Question

Need date Difference in terms of months.

If I give the FromDate as 1st Feb,2011 and ToDate as 2nd April 2011 then Its should give result as 2.2.

That means It should calculate the months first then the number of days in the decimal value.

See if date difference is 3 months and 22 days then It should give the difference as 3.22

Is it possible through the Javascript.

Answer 1

var date1 = new Date(2011, 1, 1);
var date2 = new Date(2011, 3, 2);
var diffYears = date2.getFullYear() - date1.getFullYear();
var diffMonths = date2.getMonth() - date1.getMonth();
var diffDays = date2.getDate() - date1.getDate();

var months = (diffYears * 12 + diffMonths);
if (diffDays > 0) {
  months += '.' + diffDays;
} else if (diffDays < 0) {
  months--;
  months += '.' + (new Date(date2.getFullYear(), date2.getMonth(), 0).getDate() + diffDays);
}
console.log(months)
