Vikram Samvat (Bikram Sambat, Vikram Samvat Vikram Samwat or Vikram's Era, Devanagari:विक्रम संवत्, abbreviated "V.S." or "B.S") is the calendar established by Indian emperor Vikramaditya. It is a popularly used calendar in India and the official calendar of 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. In Nepal, it begins in mid-April and marks the start of the solar new year. It is official calendar of Nepal.

Brahmananad Swami (Devnagari: ब्रह्मान्द स्वामी) (1772-1832) was a saint of the Swaminarayan Sampraday and one of Swaminarayan's Paramahamsas.

Brahmanand Swami was born Ladudan to Gadhavi Shambhudanji Aashiya and Laluba Charan in Khan village, at the foot of Mount Abu, in sirohi district of Rajasthan in 1772.

At a young age In the royal court he sang poems in Gujarati. The Rana of sirohi, impressed with him, directed to be taught Pingal (science of constructing poetry) to the child at the cost of the state, hence Ladudan was well educated and later became a part of King of Udaipurs court. Ladudan learnt pingal and Sanskrit scriptures from Ladhaji Rajput of Dhamadka, becoming a scholar in Pingal, poetry and scriptures. Ladudan earned fame and wealth by visitng stately courts of Jaipur, Jodhpur among others, which were impressed by his poetry.

Ladudan was in Bhuj where he had heard about Swaminarayan and went to meet him. Swaminarayan was addressing a gathering in Bhuj. Ladunan was attracted to him. Swaminarayan returned to Gadhada with poet Ladudan. Ladudan lived a majestic and royal life befitting a courtier. He was always clad in most precious attires and was adorning jewellery befitting royalty. Swaminarayan did not like such luxurious life style but instead of preaching directly he changed Ladudan. He did so and became an ascetic. On the way from Gadhpur to Siddhapur, there is one small village named Gerita. Swaminarayan stopped at Gerita and administrated Bhagwati Deeksha (initiation as sadhu) to Ladudan by giving sainthood name 'Shrirangdasji.' After some time, he renamed him as Brahmanand Swami.
