mozilla-calendar 2:1.7.12-1.1ubuntu2 (amd64 binary) in ubuntu dapper

 Mozilla calendar is user-friendly todo organizer, calendar and reminder.
 It's integrated with Mozilla Mail - you can email alarms to any email
 address! Keep all your appointments or memos in one handy electronic
 format, accessible from anywhere in the world. Receive reminders
 automatically - know your dentist appointment is near without having to
 tack a note onto the fridge. Repeating events and multiple views are
 also supported.
 The calendar uses the iCal standard for storing its calendar data.
 You can publish events from the calendar to an FTP server or a webDAV
 enabled webserver. You can also use the calendar to subscribe to these
 events (share your calendars) as well.
