I really can't see how this can happen, nor why `i d' should
apparently behave differently for you to how it does for me.

Please post the value of the following variables:

calendar-day-name-array
calendar-day-abbrev-array
calendar-month-name-array
calendar-month-abbrev-array
diary-date-forms

Lots of emacs-w3m stuff, but no obvious problems.

Please try moving all files and directories in your site-lisp
directory somewhere out of the way, restarting Emacs with the -Q
option, and repeating the experiment.

Please also post the exact minimum diary file that causes the error.

Thanks.
