Task Till Dawn is a free task scheduler which can execute your repetitive tasks (i.e. open files or applications) at specified times or intervals. For example, use Task Till Dawn to automatically let iTunes download the newest Podcasts at a specified time. Or let it backup your important files every day. Needless to say, tasks can also be executed manually
The application is written in Java and therefore basically platform independent. Currently, versions for Windows and Mac OS X (Intel) are available. A Linux version will probably also be available in the future.
The project is provided under the GPL, pre-compiled versions are available in the downloads section. The application is multilingual (English, German, Spanish and French).
