Rainlendar is a customizable calendar that stays out of your way but keeps all your important events and tasks always visible on your desktop. Rainlendar uses the standard iCalendar format to store events and tasks so you can easily transfer them between applications.

The appearance can be customized with skins and you can even mix different skins. The program is very lightweight and uses almost no resources so it won’t slow down your computer. You can also run Rainlendar using the Lite version which has some limitations in the features compared to the Pro version (see the differences between the versions).

Rainlendar is platform-independent so you can run it on Windows, Linux, and Mac OS X. The application is really small in size (the distribution package is less than 2 MB) but despite its size, Rainlendar has lots of features and it supports customization. It also has multilanguage support so you can use the language you prefer.

The software also supports events and tasks which both are kept in separate lists. You can see either one or both of them at the same time. Rainlendar is highly customizable so you can modify its look and feel to suit your taste.
