AllDay is an application to produce all kinds of calendrical information in the context of a year overview. It is meant as a complement to scheduling and planning software. It is to cope with the basics of calendar computing rather than scheduling or planning tasks.
AllDay has been developed originally for the Apple Macintosh back in 1991, later it was ported to Windows and finally this Java version was built. The Mac and Windows versions reached a broad public and especially the Windows version already had a lot of different features.
This Java version of AllDay is hoped to increase distribution to the Mac, Unix and Linux worlds.
