calendaristice

Calendaristice is an interdisciplinary study concerned with calendar systems and timekeeping. It covers how calendars are constructed, their astronomical bases, mathematical schemes for intercalation and date arithmetic, and the social, religious, and political roles calendars play in societies. The term is a neologism used in some contemporary discussions and design literature to describe a structured approach to analyzing, comparing, and reimagining calendar frameworks.

Its methods include comparative analysis of solar, lunar, and lunisolar calendars; reconstruction of historical reform processes; computational modeling of date calculations; and ethnographic study of cultural practices surrounding time reckoning. Subfields examine the astronomical cycles that calendars track (the solar year, lunar month cycles, solstices and equinoxes), the rules that align cycles (intercalation, leap months), and the symbolic meanings attached to dates.

Historically, calendar studies have been conducted within astronomy, history, and anthropology; calendaristice as a standalone term has emerged only in recent scholarship or speculative literature. In practice, researchers may use related terms such as calendrics, calendrology, or calendar science. Applications include the design of new calendar proposals, analysis of historical reforms, and development of software libraries for date conversion, scheduling, and cultural localization.

Although not universally recognized as a distinct discipline, calendaristice provides a framework for comparing diverse timekeeping systems and for exploring how calendars structure daily life, governance, agriculture, and ritual calendars across cultures.
