I am not able to view the calendar

Hi,

I am not able to view the calendar even after enabling necessary modules. I tried to create one content page using datetime_field. But even then I am not able to view calendar in my site. I checked it in block and I assigned "Calendar Legend" to the left block. But it is not appearing anywhere.

I am also not getting calendar setting in administrator page.

Please do help me to solve this problem.

Thanks in Advance.
