[Typo3] e-mail reminder for calendar?

[Namuk Tscholak]

Hi,

I browsed through all available calendar extensions but it seems to me, 
that there is actual no ext which is able to send an e-mail reminder.

It should be possible to define the e-mail address/es for each event 
separate and also to define the date/time for sending the reminder 
independent of the date of the event itself.

Is there an extension which is able to do that or has that kind of 
mechanism?

best regards
