Cyclocke is a Cycle Clock, using the Gregorian calendar method. The Gregorian Calendar started Thursday, Oct. 15, 1582. (But Cyclocke will go back or forward 5 million years). The Julian Calendar before that was just a feeble approximation of the Gregorian one. So longer cycles should be fairly represented for Julian dates as well
Our Review: Cyclocke shows the alignments of moon, stars etc and gives the user all the relative information in the Georgian clock layout as opposed to the more common Julian layout. There's an excellent tutorial included which helps make this an interesting tool for the reinterpretation of linear history.
