Some “calendars” listed are identical to the Gregorian calendar except for substituting regional month names or using a different calendar era. For example, the Thai solar calendar (introduced 1888) is the Gregorian calendar using a different era (543 BC) and different names for the Gregorian months (Thai names based on the signs of the zodiac).

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.
Regional or historical names for lunations or Julian/Gregorian months
Learn how to design a calendar that’s both functional and inspirational. This course begins by taking a historical look at the different types of calendars. Next, author Nigel French takes you through three different projects (a wall calendar, a circular calendar, and a compact one), using both Adobe InDesign and Illustrator.

This is a list of calendars. Included are historical calendars as well as proposed ones. Historical calendars are often grouped into larger categories by cultural sphere or historical period; thus O’Neil (1976) distinguishes the groupings Egyptian calendars (Ancient Egypt), Babylonian calendars (Ancient Mesopotamia), Indian calendars (Hindu and Buddhist traditions of the Indian subcontinent), Chinese calendars and Mesoamerican calendars. These are not specific calendars but series of historical calendars undergoing reforms or regional diversification.
