A calendar is a system for naming periods of time, typically days. These names are known as calendar dates. The dates may be based on the perceived motion of astronomical objects. A calendar is also a physical device (often paper) that illustrates the system (for example, a desktop calendar) — this is the most common usage of the word. As a subset, 'calendar' is also used to denote a list of particular set of planned events (for example, court calendar). Calendar - Calendar systems. Including:

Today there seems to be two different calendar systems that are presenting themselves as Mayan alternatives to the Gregorian calendar. One of them is the so-called Dreamspell/Thirteen Moon calendar and the other is the traditional Mayan calendar system, which revolves around the Sacred Calendar that is still in use in certain parts of Guatemala. As we are approaching the Oneness Celebration and the ensuing Return of the Calendar of Quetzalcoatl it is becoming all the more important to discuss the differences between these two calendars.
