Natural Time-Series Analysis and Vedic Hindu Calendar System

Abstract: Worldwide, calendars are classified into three categories, solar, lunar, and lunisolar, based on motions of Sun, Moon, and both, respectively. Being lunisolar, the Vedic Hindu calendars are capable of considering both solar and lunar activities. Therefore, these calendars can have potentially an upper hand over solar and lunar calendars. Several natural activities on the earth are due to the influences of the Sun and Moon, and the Hindu calendars are able to observe these patterns. Time series analysis plays a very crucial role in day-to-day applications and is one of the major components in the field of data science. The modern computations (including time series analysis) are performed with the Gregorian (solar) calendars. In this paper, the potential of the Hindu calendar is discussed from the time series analysis point of view. Some logical and experimental comments are discussed in this paper to motivate to dig further possibilities in the domain.
