Mozilla Sunbird may be just what you need to help you manage your appointments and tasks on Linux.
The Firefox web browser and the Thunderbird email client are standard applications on Linux. Both programs are developed and maintained by the Mozilla Foundation. Mozilla also has the fairly young and virtually unknown calendar application called Sunbird [1]. The stable 0.5 version is suitable for production use, despite the low version number.
Sunbird is the Mozilla Foundation’s second calendar application, and you would be forgiven for mistaking it for its sibling Lightning. Lightning relies on the presence of Thunderbird, whereas Sunbird is a standalone application that will run on almost any Linux system.
