problem with /usr/bin/calendar

Hi:

 I am having a minor problem with the calendar utility (man 1
calendar). I have created a ~/.calendar/calendar file but when I type:
$ calendar

 I get the entries for all the calendars stored in
/usr/share/calendar. I moved /usr/share/calendar/calendar.all to a
different file name and then ran $ calendar. Nothing appeared so it
seems that calendar is trying to use that file. However I can only get
it to use the user created calendar file by doing

$ calendar -f ~/.calendar/calendar

Is there some setting I have to make elsewhere? According to the man
page it should search my home directory for a calendar file.
