Downloading WebEvent 4.0 for Mac from the developer's website was possible when we last checked. We cannot confirm if there is a free download of this app available. The program lies within System Tools, more precisely General.

From the developer:
WebEvent is an interactive World Wide Web calendar that allows you to view and modify calendar-type events from any computer that can run a Web browser. You can manage personal, departmental, and company-wide schedules from any computer (anywhere on the planet) that runs a Web browser. Maintaining and supporting WebEvent is a snap because no other software needs to be installed on individual computers.
You may want to check out more Mac applications, such as InsomniaT, Notifications Scripting or IBM Performance Analysis Suite, which might be related to WebEvent.
