I have just released an alpha demo version of a new application I have been working on. Multi Event Filter is a utility designed for quick and easy transfer of multiple events from text into the OSX Calendar application.
Download Multi Event Filter on the Mac App Store
Multi Event Filter utilizes and extends Apple's Data Detectors, giving access to event information from applications which do not support them directly.

Here you'll find my software for OSX like Dates to iCal, iCal Dupe Deleter and iCal Reply Checker plus some applescripts amongst other things.
