A calendar was implemented on a Raspar system planet. Among the months included in this calendar were Ensi, Stolivea, Aint, Nnters, Hinggnih, Neevlit, Dha, Bababbb, and Aaaaaalt.
The origin of this calendar can be traced to a single-page weather prediction, "Region 29: The West Fissure," authored by Bob Carrau. This forecast was featured in the 1993 book Monsters and Aliens from George Lucas, a compilation of concept art and images from different George Lucas ventures. According to Leland Chee, a Lucasfilm staff member responsible for the Holocron continuity database, the content within this book is considered non-canonical.
