LB | Calendar for all Date input fields | Not showing correct month when clicked

Environment: LB
Company: UK Benefits for Hspl
Issue: calendar should display the month for which the date is present not the currebnt month

Steps:
Ex: Change Classes Page

Change Classes > Class Change Date input text field > 25/12/2016 > Save
Click on date field > Calendar shows current month instead of December month

Verified the same on Stage, for stage it is showing the month Dec. month.

This change is applicable to all date format and through the pages mentioned in NF-8 and NF-16 where date field is input field.
