Calendar
Lettistan uses a strange version of Solar Hijri calendar, the Juche calendar (Chinese:主体历) which begins with the "birth" of Letty Whiterock, actually not the founder of Lettistan. Her "birth year", 1382 (Only includes the part on and after Gregorian August 17 2003) in the Solar Hijri calendar, is "Juche 1" (Chinese:主体元年) in the Juche calendar. Most part of Gregorian 2023, or Solar Hijri 1402, is Juche 21 (主体21年).
Besides the Juche calendar, Gregorian calendar, Lunar Hijri calendar and "traditional" Solar Hijri calendar are also still being used in Lettistan.
Media
The state news agency of Lettistan is the Lettistani Central News Agency (LCNA)(Chinese:蕾蒂斯坦中央新闻社, 蕾中社).
