Calcurse is a calendar and scheduling application for the command line.
It helps keep track of events, appointments and everyday tasks. A
configurable notification system reminds user of upcoming deadlines, the
curses based interface can be customized to suit user needs and a very
powerful set of command line options can be used to filter and format
appointments, making it suitable for use in scripts.

There is an optional dependency on python3-httplib2 if you want to use
the calcurse-caldav utility.
