Hi,
There is no official plugin for this and there is none yet in the marketplace. I have checked the Wordpress official plugin repository and found one
http://wordpress.org/extend/plugins/events-made-easy/ that could be what you are looking for.
Please be aware that this plugin is not yet officially tested by AppThemes and so install with caution. Backup your database first, just to be on the safe side.
Anyway, I am moving this thread to the Plugins Exchange section.
Cheers.
