Calender feature and start date end date settings

[Priyanka]

While creating a task we can set up start date and end date (this is currently locked in trail version) .

If i modify the start and end date in the ticket itself,  will it be reflected in calender as well ?

(if we set up dates in calender directly or from the calender option in the ticket or with simple drag drop , the calender will be modified, but this case is different; there is start date and end date feature is available in tasks itself, in that can we modify calender by changing the date? ).
