  The Vikram Samvat has been used by Hindus, Sikhs, and Pashtuns. One of several regional Hindu calendars in use on the Indian subcontinent, it is based on twelve synodic lunar months and 365 solar days. The lunar year begins with the new moon of the month of Chaitra.
  
  The calendar remains in use by people in Nepal serving as its national calendar where the first month is Baisakh and the last month is Chaitra. It is also symbolically used by Hindus of north, west and central India. Alongside Nepal Sambat, Bikram Sambat is one of two official calendars used in Nepal. In south India and portions of east and west India (such as Assam, West Bengal and Gujarat), the Indian national calendar is widely used.
  
  With the arrival of Islamic rule, the Hijri calendar became the official calendar of sultanates and the Mughal Empire. During British colonial rule of the Indian subcontinent, the Gregorian calendar was adopted and is commonly used in urban areas of India. The predominantly-Muslim countries of Pakistan and Bangladesh have used the Islamic calendar since 1947, but older texts included the Vikram Samvat and Gregorian calendars. In 2003, the India-based Sikh Shiromani Gurdwara Parbandhak Committee controversially adopted the Nanakshahi calendar.
