standalone calendar application - sunbird dead and no replacement in sight

@wolfgangcr

it would be interesting to discuss this, but off-topic (sorry for raising the issue).

So nobody has any suggestion for getting a working calendar on my system, given the wish list stated above?

Ideally by revitalizing the sunbird project, or at least by fixing the single bug that seems to be prohibiting its use for me. Or else by fixing the widely recognized thunderbird/lightning problem.

Have you looked at Zimbra Desktop.
