I would like to extend calendar to handle more styles of date
# MONTHNAME DAY
# MONTHNAME DAY, YEAR
# Any of DAY, MONTH, or MONTHNAME, YEAR can be `*' which matches any
# day, month, or year, respectively.
# Names can be capitalized or not, written in full, or abbreviated to
# three characters with or without a period.
And of course it should also ignore lines starting with '# ' (comments! :-)
(which with the whitespace can be fairly easily used in conjunction with
CPP-like constructs such as the '#include')

I think this would be much better written as:
1962/07/01 +15 message to display %y years ago
I.e. specify the starting date of the anniversary and then allow
something like '%y' to expand to the delta in years (and maybe also have
other '%' expansions that make sense for anniversaries too).

I think the '+N' trigger should always/only be at the beginning --
i.e. the first thing after the date.
With the changes I propose I could make calendar and my emacs diary file
compatible, which would help me a lot too.
On the other hand there's always pkgsrc/time/cal (and 'remind').... :-)
