@shima96160,

In JavaScript month starts from 0(January) and ends at 11(December). So while displaying they are incremented by 1. However, you can use ISO format to pass month from 1 to 12 (Example: “2015-03-25” is considered as March 25, 2015). You can adopt the one of the format to fit your requirements.
