Ancient Greek calendars

Various ancient Greek calendars began in most states of ancient Greece between Autumn and Winter except for the Attic calendar, which began in Summer.

The Greeks, as early as the time of Homer, appear to have been familiar with the division of the year into the twelve lunar months but no intercalary month Embolimos or day is then mentioned, with twelve months of 354 days.^[1] Independent of the division of a month into days, it was divided into periods according to the increase and decrease of the moon. Thus, the first day or new moon was called Noumenia. The month in which the year began, as well as the names of the months, differed among the states, and in some parts even no names existed for the months, as they were distinguished only numerically, as the first, second, third, fourth month, etc.

Of primary importance for the reconstruction of the regional Greek calendars is the calendar of Delphi, because of the numerous documents found there recording the manumission of slaves, many of which are dated both in the Delphian and in a regional calendar.

Calendars by region[edit]

Aetolian[edit]

The months of the Aetolian calendar have been presented by Daux (1932) based on arguments by Nititsky (1901) based on synchronisms in manumission documents found at Delphi (dated to the 2nd century BC).^[2] The intercalary month was Dios, attested as Dios embolimos in SEG SVI 344, equivalent to Delphian Poitropoios ho deuteros. The month Boukatios corresponds to Delphian Daidaphorios, while Delphian Boukatios is Aetolian Panamos. There has been no argument to dispute the order of months, so the months found by scholars are agreed upon to be the most likely for the time. Unfortunately, there is no convenient table that describes the synchronisms, as one inscription is given for all the months. The only month to have a singular document describing it is the eleventh month, in comparison to the other numerous documents for the rest of the calendar. The Aetolian calendar was used across the League, and additionally, one could find the Aetolian calendar in use across western central Greece until the league dissolved circa the second centur BCE. ^[3]

Boeotian[edit]

The history on the Boeotian calendar is very limited as not many detailed records were kept. All months months were named, numbered, and adjusted according to the seasons to fit the lunar year. A calendar was used as a reference in archaic times that bore resemblance to better known Greek city-states and their calendar systems. Any early evidence of the Boeotian calendar comes from Hesiod and is debated for interpretation. Hesiod’s recollection of the months includes only one (Ληναιων – Lynion) and this does not appear on any of the other calendars associated with Boeotia. This gap in information suggests to scholars a change in the organizing of months between the archaic and classic times in Boeotia. As most other regions in Greece, Boeotia divided their calendar months into thirds, but had differing ways to count the days. One system represented the days by ordinal numbers, another used common Greek terms to divide the months in half, and the third system indicated a division of the month into decads. With such a diversity in how the months themselves were categorized, it is hard for historians to give a definitive answer on the calendar. ^[3]

Elian[edit]

Information about the Elian calendar is scarce and very desolate. Most of the information found depends upon a scholar by the name of Pindar, and while he names some months and the organization of the calendar, much is still unknown. Pindar’s work is left to interpretation and such, causes dispute among scholars to which version is correct. The one conclusion that is well known depends upon the Elian calendar beginning at the time of the winter solstice. However, this is still contested as to why the calendar would have a relationship with the seasons, when it may not have revolved around them in the past. As most other calendars agree, there is much evidence to suggest that the Olympic Games were hosted in the summertime, which would be reasonable to suggest this as the beginning of the year. This is the case with Athens and many regions would model their calendar after it. It would be reasonable to conclude that Elis would follow this example also, which refutes the idea of beginning at the winter solstice. ^[3]

Epidaurian[edit]

The Epidaurian calendar was from the Epidauros region in ancient Greece and most extensively declared to be the formal calendar in circa fourth century BC. Construction of the calendar was put into effect by a German born mathematician named Abraham Fraenkel and appears to be the most widely accepted version of the order. ^[3]

Laconian[edit]

Laconian calendar has several months that are presumed to follow the Spartan calendar, and even include a few of the same months (Ἑκατομβεύς, Κάρνειος, Ἡράσιος). As so many months are attested to be Spartan or belong to the surrounding Spartan areas, it is presumed that Sparta and Laconia could have shared a calendar. There is very little epigraphical data for the names of days in the Laconian calendar. The calendar has a few numerals associated with the days but there is no way to specifically determine terminology for any of the days. ^[3]

• Karneios – Κάρνειος

Locris[edit]

Locris itself appears to be divided into Eastern Locris and Ozolian Locris. Eastern Locris has almost no remains for its calendars, but still enough to show that two neighboring towns would have different calendars, as far back as the first century BCE. Three months in the Eastern Locris calendar have comparable months with Skarpheia and two months have comparable months with Thronion. Neither Skarpheia nor Thronion can shed light on the order of the months though. Additionally, only one date is confirmed and it corresponds to the month found in the Thronion calendar. This date is known as τεσσαραχαιδεχάτα.^[3]

Skarpheia months

• Aphamius – Άφάμιος
• Ermyios – Έρμάυιος
• Pyllichos – Φύλλιχος

Thronion months

• Ituios – Ἱτώυιος
• Hippios – Ἱππείος

The Ozolian Locris calendar came into being after Locris broke free of Aetolia’s reign after the dissolvement of the Aetolian League. This is when an affirmed calendar has been located, reaching back as for as the second century BCE. All of the months found in the Ozolian Locris calendar have been attested except for the second, ninth, and eleventh month. In particular, the Ozolian Locris calendar aligns with the Delphian calendar to show that the first month corresponds to Boukatios at Delphi, and the rest follow sequentially. However, most of the information known about Locrian months comes from Delphi, and very little is indigenous to Locris. As for days, only the first twenty days are confirmed in the calendar. Earlier translations lean toward the dialect with alpha, while later ones use the koine form with eta. It is not until before the first century of the Christian era that numerical names begin.^[3]

Ozolian Locris months (in order)

• First – Πρώτος
• Second – Δεύτερος
• Third – Τρίτος
• Fourth – Τέταρτος

Rhodian[edit]

Evidence for the Rhodian calendar is plentiful and comes from a multitude of inscriptions. All of the months in the year are presented and attested for, as well the count of days. However, while the names are known, the order and organization of the months is not a definitive answer. For the amount of resources found on the actual calendar, very few ancient sources mention the calendar in their writings. With the plethora of information accessible, the Rhodian calendar is one studied almost extensively as the Athenian calendar.^[3]

Thessalian[edit]

The Thessalian calendar was quite similar to the calendars of Pelasgiotis and Hestiaiotis. In Thessaly, the months were divided into semesters known as πρώτη and δζυτέρα έξάμηνος. The order of the months was pieced together from different sequences in ancient inscriptions. Although Thessaly had different months then those of surrounding areas such as Perrhaebian and Magnesia, the methodology of counting days within the months were similar. In Magnesia, however, the months were named after gods, such as in other Greek regions. Three decades were used and a decade plus a number suggests that in the last decade, the Thessalian region counted backward.^[3] The Thessalian calendar was standardized only in the Roman era. Previously, all poleis had their own calendars based on their respective festivals.^[6]
