Observing the Illusion of Historical Time

There have been many calendar systems in the world. There are calendars that are no longer in use, and we can presume that calendars have been lost to us over time. Because of the influence of western civilization, the Gregorian calendar is in common use today. Much like a shared language, calendars orient people to large spans of time. The Gregorian calendar is used as a universal standard, and is important in discussing historical research and scholarship. Calendar dating helps students and scholars organize data and information. “The Guide to Historical Dating—Centuries” below is presented to assist in understanding the spans of time under discussion in reference to centuries (100 Year Increments).
