Perplex City
Calendar
Especially unusual about Perplex City is it's entirely unique calendar, which is important to establish. The year 1737 AD is marked being the start of a new calendar for Perplexian Society. The year 1736 AD is marked as year 0 BC. Everything after that time is referred to as AC, and everything before is referred to as BC. It is unclear what exactly prompted the shift, however it is quite important to take into consideration when dealing with the full scope of history involved in a lengthy study. By many appearances, the perplexian calendar is especially used in relious and historical contexts. The common belief is that it has something to do with The Cube. However, because to the Cube was discovered in the year 7 AC, this alone seems unlikely. Some have pointed out: in 1737 there was indeed a syzygy, wherein Mercury crossed Venus' path, as observed by John Bevis. It is the only such event in recorded history.
