High Quality Content by WIKIPEDIA articles! Vikram Samwat is the calendar established by Indian emperor Vikramaditya. It is a popularly used calendar in India and the official calendar of Bangladesh and Nepal. The Vikrama Samvat was founded by the emperor Vikramaditya of Ujjain following his victory over the Sakas in 56 BCE, although it is popularly (and incorrectly) associated with the subsequent king Chandragupta Vikramaditya. It is a lunar calendar based on ancient Hindu tradition (see Hindu calendar and Vedic time keeping). The Vikram Samvat calendar is 56.7 years ahead (in count) of the solar Gregorian calendar. For example, the year 2056 BS began in CE 1999 and ended in CE 2000. In Northern India the calendar starts with the first day after the new moon in the month Chaitra, which usually falls in March/April in the Gregorian calendar. Again in Western India the same era begins with the first day after the new moon in the month of Kartika which usually falls in October and November in the Gregorian calendar.
