^{Indian Calendar}

^{The Hindu calendar system is based on the lunar months. The most commonly used dating systems in India are: विक्रम “Vikram” and शक Shaka eras. The विक्रम era was founded by the legendary King Vikramaditya in 57-58 BC. Since the year begins in the month of  चैत्र (March- April), the Vikram calendar does not match with the Christian calendar. Vikram dates are usually identified by the Sanskrit word  संवत्   ‘year/era.’}

^{There are six seasons and twelve months in the Hindu calendar as shown in the following chart.}

^{A Month: Each lunar month is divided into two phases, पक्ष m.. The BRIGHT phase, शुक्लपक्ष m., lasts from new moon to the full moon, whereas the DARK phase, कृष्ण पक्ष m., lasts from the full moon to the new moon. Each Phase is divided into fifteen days, consisting of either the day of the full or new moon. The fourteen days of both the phases are Sanskrit ordinal numbers but the fifteenth day of the bright phase is called अमावस्या f. “ the full moon” while the fifteenth day of the dark phase is called पूर्णिमा f. “the new moon.”}

^{A leap month called मलमास / अधिमास is added after every thirteen month in order to adjust for the discrepancy between the lunar calendar and solar calendars.}
