There is a jewish calendar plugin for korganizer, which could probably
provide a guide to creating a similar one; however, I believe this
plugin may simply change the display information. Since the expressions
in the date format can be C expressions, according to
you should be able to put the conversion needed for the calculation as
part of the expression.
