previous months are not showing

[zaibazhar]

I found this very useful for me, in your example there are only one calendar, so what i did I'm showing 12 months which looks good. issue is if I select the range from 29 march to 2 aprl it will select the dates.which is fine.
what if,i m trying to edit my dates I cant not see month of march, calendar will start from april.
is there any way whatever my dates are calendar should remain same from jan to dec.
(I'm using 12 months calendar, specially for mobile, in mobile view calendars are in shape of stack)

thank you.
