Regional or historical groups:
Hijri calendar,Mayan,Aztecan,Egyptian,Mesopotamian,Iranian,Hindu,Buddhist,Pre-Columbian Mesoamerican,Hellenic
Julian or Gregorian-derived.
Calendars fall into four types
lunisolar,solar,lunar,seasonal
besides calendars with "years" of fixed length, with no intercalation. Most pre-modern calendars are lunisolar. The seasonal calendars rely on changes in the environment rather than lunar or solar observations. The Islamic and some Buddhist calendars are lunar, while most modern calendars are solar, based on either the Julian or the Gregorian calendars.
