Mozilla Calendar Project

It was developed to be part of the Mozilla Application Suite project.

It worked with Microsoft Windows, Linux, Mac OS X, and FreeBSD.

The project was initially led by OEone employee Mike Potter.

Shortly after Mike Potter and his team had to pull out of development due to other projects taking precedence,[3] Mostafa Hosseini was announced as the new project lead.

However, this plan was dropped when Mozilla decided to focus on its nascent standalone applications rather than the integrated suite.
