Rainlendar takes a different approach from the rest of the list: instead of opening a window when you need it, it keeps your calendar, events and tasks drawn on the desktop. You can show several windows at once, such as this month and next month or two separate task lists, and change the look with skins, categories and Lua scripts. Events support multiple alarms with snooze, a quick-add box accepts a single line of text with recurrence, and printing can produce lists, calendar layouts or PDFs. Data is kept in the standard iCalendar format and backed up every day. The same data, skins and scripts work on Windows, Mac and Linux, with .deb packages for Ubuntu-based systems. Rainlendar Lite is free, while Rainlendar Pro adds CSV import and export and sync with services such as Google Calendar for a one-time license fee, which the site listed in euros from our location, so the USD price is pending. It suits people who want a glanceable calendar more than a full scheduling suite.
