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.
In Classical Antiquity, the Hellenic calendars inspired the Roman calendar, including the solar Julian calendar introduced in 45 BC. Many modern calendar proposals, including the Gregorian calendar introduced in 1582 AD, contains modifications from that of the Julian calendar.
List of calendars
[edit]In the list below, specific calendars are given, listed by calendar type (solar, lunisolar or lunar), time of introduction (if known), and the context of use and cultural or historical grouping (if applicable). Where appropriate, the regional or historical group (Jewish calendar, Hijri calendar, Sikh, Mayan, Aztecan, Egyptian, Mesopotamian, Iranian, Hindu, Buddhist, Pre-Columbian Mesoamerican, Hellenic, Julian or Gregorian-derived) is noted.
Calendars fall into four types: lunisolar, solar, lunar and seasonal. Most pre-modern calendars are lunisolar. The seasonal calendars rely on changes in the environment (e.g., "wet season", "dry season") 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.
Some calendars listed are identical to the Gregorian calendar except for substituting regional month names or using a different calendar epoch. For example, the Thai solar calendar (introduced 1888) is the Gregorian calendar using a different epoch (543 BC) and different names for the Gregorian months (Thai names based on the signs of the zodiac).

Kollam Era | sidereal solar | Hindu | 825 | Kerala | It is believed that the era was started by the Syrian Christian saints Mar Sabor and Mar Proth who arrived in Kollam in the 9th century CE. This event is recorded in the Kollam Tarisappalli copper plates issued to them.[9][10][11] The news of the physical disappearance of Sri Adi Shankaracharya in 820 CE at Kedarnath reached the Malabar coast only a few years later. It is believed that Kerala began the Malayalam era in 825 CE in his memory.[12][13][14] According to Hermann Gundert, Kollam era started as part of erecting a new Shiva Temple in Kollam and because of the strictly local and religious background, the other regions did not follow this system at first. Once Kollam port emerged as an important trade center, however, the other principalities also started following the new system of calendar. This theory backs the remarks of Ibn Battuta as well.[9][15] The Kollam era may also be attributed to the legend of Paraśurāma, an incarnation of Vishnu. It is sometimes divided into cycles of 1,000 years reckoned from 1176 BCE. Thus, 825 CE would have been the first year of the era's third millennium.[16] |
