my ipad calender is hang not any movement on the screen pl help me

Reboot your iPad if you cannot get off of the calendar screen and see if you are able to navigate the iPad properly after the iPad restarts.

Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.
