Kdepim

Kontact is a personal information manager (PIM) and groupware software suite developed by KDE. It supports calendars, contacts, notes, to-do lists, news, and email. It offers a number of inter-changeable graphical UIs (KMail, KAddressBook, Akregator, etc.) all built on top of a common core.

KAlarm is a personal alarm message, command and email scheduler application integrated with the KDE desktop environment. When a scheduled alarm goes off, KAlarm can display a text message or image file, run a command, send an email or play a sound file, acting like an alarm clock. KAlarm supports the scheduling of multiple alarm times and alarm dates. Aside from control through the graphical interface KAlarm can also be operated using the command line.
