Can't import Calender in java.util.Calender

[Mrpeabody]

I recently tried to write a program trying import Calender so that I
could use it and I got the Error: Class java.util.Calender not found in
import.  I have my classpath set to include my classes.zip and my
swingall.jar and it has worked find on all the other programs I have
work on up to now?  I even upziped the classes.zip to make sure it
contained calender and it did.  Can anyone help me with this problem
please.
