Within the depth-psychology corpus, 'calendar' functions as far more than a chronometric instrument: it emerges as the primary cultural technology through which a civilisation encodes its relationship to sacred time, cosmic order, and the mythic substrate of existence. Eliade furnishes the conceptual anchor, arguing that the sacred calendar is the structural mechanism of the 'eternal return' — the periodical reactualization of primordial divine events that collapses profane duration into mythic simultaneity. Von Franz extends this into comparative mythology, demonstrating how Chinese imperial and Mesoamerican (Mayan, Aztec) calendrical systems fused temporal reckoning with deity, each day carrying its own numinous identity and ritual obligation. Burkert grounds the discussion in historical particularity, showing that Greek religious life was organized almost entirely through festival calendars, with the order of festivals constituting the calendar's substance, and each city-state maintaining its own local variant. Kerényi discloses the astronomical archaeology beneath Greek cult, tracing the Sirius-based new-year calendar to Minoan antecedents. Harrison illuminates the calendar's function in marking the eniautos-daimon cycle — the yearly death and renewal of fertility powers. Hesiod's Works and Days reveals the calendar operating at the most intimate agricultural and domestic level, where each day bears specific auspicious or inauspicious qualities. A persistent tension runs through the corpus between the cyclical time of archaic ritual and the linear time of historical consciousness, with the calendar positioned at precisely that contested threshold.
The sacred calendar annually repeats the same festivals, that is, the commemoration of the same mythical events. Strictly speaking, the sacred calendar proves to be the 'eternal return' of a limited number of divine gesta.
Eliade defines the sacred calendar as the institutional form of the eternal return, a periodic mechanism for reactualizing mythical time and divine paradigmatic acts.

The greatest task of the Chinese emperor was to keep the numbers of the calendar in order. He was the maker of the calendar, and he had to see that the days coincided correctly with the will of heaven.
Von Franz presents the Chinese imperial calendar as the supreme instrument of cosmic governance, wherein each day is ritually differentiated and the emperor functions as the mediator between temporal and celestial order.

Not only did the Maya consider time as a deity (the sun god) but every year, month, day and even hour was identical with a number and was at the same time a god.
Von Franz demonstrates that in Mayan and Aztec systems the calendar was not merely a measurement device but a theophanic structure in which every temporal unit was simultaneously a divine being.

The living religious practice of the Greeks is concentrated on the festivals, heortai, which interrupt and articulate everyday life. The order of the calendar is largely identical with the sequence of festivals.
Burkert establishes that for the ancient Greeks the calendar was not an abstract grid but the ordered sequence of sacred festivals, with each city-state possessing its own particularist religious calendar.

Leading religious and political sites in Greece, such as Olympia, Delphi, Athens, and Epidauros, chose the month of the early rising of Sirius as the first month of the year. This calendar would be exceedingly strange if the Greeks had not inherited it from an earlier culture.
Kerényi traces the Greek new-year calendar to Minoan astronomical inheritance, arguing that the Sirius-based reckoning reveals a cultural continuum reaching back beyond historical Greece.

This periodic 'salvation' of man finds an immediate counterpart in the guarantee of food for the year to come (consecration of the new harvest).
Eliade links the calendrical ceremonial of periodic regeneration to both ontological renewal and agrarian subsistence, resisting a reduction of ritual time to mere agricultural utility.

The festival calendar adds the element of sacred time to the sacred space of the Daoist monastery or temple. It integrates religious activities into the annual curriculum of a predominantly agricultural society by merging economic interests with spiritual quests.
Kohn shows that the Daoist festival calendar functions as the temporal counterpart of sacred space, synchronizing agrarian cycles with ritual practice and constituting a 'ritualized form of time control.'

Only a calendary explanation, that is, a tradition based on a calendar older than that of Alkaios' time, can account for the inconsistency of Apollo's being sent by Zeus to Delphi but driving his swan chariot to the land of the Hyperboreans.
Kerényi uses the concept of a pre-existing, archaic calendar to resolve apparent mythological inconsistencies in Apollonian cult narratives, positioning calendar history as a tool of myth interpretation.

When the year is fixed by the solar period, we get festivals of the type of the Roman Saturnalia or the Greek Kronia, and the single combat appears as the driving out of winter or of the dying year by the vigorous young spirit of the New Year.
Harrison demonstrates how the solar calendar structures the eniautos-daimon mythology, with the year's turning providing the ritual occasion for the symbolic death and replacement of the fertility spirit.

The ninth, two days at least of the waxing month, are specially good for the works of man. Also the eleventh and twelfth are both excellent, alike for shearing sheep and for reaping the kindly fruits.
Hesiod's Works and Days presents the oldest extant Greek calendrical text in the depth-psychology corpus, showing each day as qualitatively differentiated and carrying specific auspicious or inauspicious properties for human activity.

In India our present world age, the Kali Yuga, is supposed to have commenced on February 17, 3102 B.C., which is but eleven years before the Mayan basal date.
Campbell proposes a trans-cultural correspondence between Indian and Mayan cosmological calendars, suggesting that shared astronomical principles may underlie independent civilizations' selection of world-age inception dates.

The Nawroz, the Persian New Year, is at once the festival of Ahuramazda (celebrated on the day 'Ormazd' of the first month) and the day on which the Creation of the world and of man took place.
Eliade identifies the New Year festival as the calendrical pivot at which cosmogony is periodically re-enacted, conflating the temporal origin of the year with the mythological origin of the world.

The purpose of the Demiurge is that mankind shall learn to count and develop mathematics by the exercise of reckoning periods of time, days, months, and years.
The Timaeus situates the calendar's origin in divine teleology: the heavenly revolutions are instituted precisely so that rational beings may develop number and temporal reckoning.

In the refrain, it will be remembered, the Kouros is bidden to come to Dikte 'for the Year' (eis eniauton), and, when the aetiological myth has been recounted, it is said 'the Horae began to be fruitful year by year.'
Harrison reads the Kouros hymn as evidence that the Greek eniautos cycle — the yearly return of the divine youth — was the mythic substratum structuring the sacred calendar's seasonal festivals.

A highly developed calendric system yielding a pattern of interlocking large and smaller cycles, an assignment of deities to the various heavenly spheres and a notion of the horoscope, the idea of cycles of creation and dissolution.
Campbell catalogues the Mesoamerican calendric system among a suite of civilizational parallels with the ancient world, treating it as evidence of a shared mythological substrate underlying independent cultural development.

The movements of the Sun and the Moon became the basis of the astrological system. But these movements are considered not principally as celestial phenomena in themselves, but as pointers to the dynamic changes of the solar and lunar life-force as expressed on Earth.
Rudhyar grounds the origins of the astrological calendar in the vitalistic reading of solar and lunar cycles, interpreting the calendar as a map of life-force dynamics rather than a neutral chronometric grid.
